All About Valves

I need to turn off the supply of water to my shower. I found the back access panel, opened it up and am looking at the Valves to turn off the supply of water. They are very hard to turn either way, but I dont know which way to turn them, to turn off the supply of water.

Just remember: Righty tighty, lefty loosey (except for explosive gas). To the right is tight — off.

How do the numbers of cylinders, valves, and cam shafts affect an engine? Also, what effect does the volume have?

The more cylinders, the better the smoothness, torque, less vibration, but worse mpg and cost.
More Valves add more high-rev power to an engine due to the more efficient mixture filling.
No. of camshafts depends on engine layout (in-line, V, flat) and on no. of valves. More camshafts doesn’t necessarily mean better valve control, but it makes the engine more expensive.
The volume (ie, engine displacement) is more important than sheer power. The greater the displacement, the better the power progression, the torque and worse mpg. Current trend is to squeeze ever more power from the low-displacement engines.

ideally one on each faucet and one on the main main one on the toilet

In the heart, do the semilunar Valves have cords or muscular support?

Do you not know how to use search engines to search for info?

I offered Pur water filters my Patent Pending Idea to update their old water filters to use Auto Flush Technology, However, A.G. Lafley and his staff saw no value in Auto Flushing the kitchen Tap water filters as they see no value in help protecting their customers health. It is fine to let people forget to manually flush their systems as the black particulates that carry impurities and bacteria and other contaminates as well as chlorine and such is obviously just fine if their customers drink it, well then if it is safe to drink it, then why do we need the water filter in the first place?

When people use kitchen tap water filters they must activate the filters for 10 to fifteen seconds on first use….Must Manually flush prior to every use, For nearly thirty years they have not updated this horrible pain in the Ass! If I forget to Manually Flush then I get black particulates into my drinking water glass, which they claim is harmless and that is a Lie!

Proctor and Gamble and Mr.AG.Lafely hate Auto Flush Technology but Proctor and Gamble obviously do not care enough about their customers Health and Well being to add Auto Flushing to your water filters!

Shame on you Mr. Lafley!!! lafley.ag@pg.com

A simple process to make our lives easier and safer and they won’t do it! You think it is o.k to drink Black Particulates and bacteria and residue from a used and or dirty filter. When all you have to do is ensure that a control board can be programmed to control Valves and the water flow.

Rest assured the process of Auto Flushing is going to be circulating on forums and news sites until some water filter company cares enough about our welfare to start adding Auto Flushing to their systems. Hell isn’t it time! faucets are automated, doors and even soap dispensers and paper towel dispensers!

Shame, Shame, Shame on you and Proctor and Gamble!
This posting is starting to show up on forums already…

Kitchens and bathrooms have become the sole largest selling point in houses today. It is not uncommon for the simplest tract home to have a $60,000 kitchen remodel and the surprising thing for us old timers is that this investment returns dollar for dollar(if not multiples above) in appraised value of the home as well as esthetic influence to the new buyer. In this remodel the current trend is to stainless steel appliances, granite or at least solid surface counter tops and the ultimate in style, design and finish in fixtures.

There a literally hundreds of choices when it comes to bathroom and kitchen faucets . These choices can range in cost from below $100 to into the $1000’s with the emphasis invariably being on style or design as opposed to function. In past days if you turned the faucet and you got water then you considered it was better than going out to the well and pumping. If the water got hot it was a miracle. Yes folks I’m just about old enough to remember those days.Today is it the latest style? Polished nickle, stainless steel or oil rubbed bronze? Does the soap dispenser match? Soap dispenser? How does a faucet match the bar of Ivory soap laying on the drainer?

Then there was the leaking. If you had enough strength to turn the knobs hard enough then you got no leaks. Good news, today, is that all, except the cheapest faucets, can last a lifetime and rarely leak and many come with lifetime replacement guarantees either for parts or sometime even for full replacement of the faucet. I read in a discussion forum, 2 weeks ago, that a customer had called Moen to hopefully get some replacement parts for a faucet that was 17 years old. The customer service person regretted to inform him that the parts for that faucet had long since become unavailable so they were just going to send him a brand new faucet. Take a little time and find a faucet that you like since it’s going to be with you for a long time. So we CAN take less time worrying about leaks and more about quality finish, style etc.

Even with this newly found carefree attitude you still need to understand what to look for to get the best product and to understand the function of a faucet so that if and when something does go wrong you can understand and not panic and head for the closest big orange box. A faucet consists of three parts, a valve that controls and directs the flow of water, a handle(s) or knob(s) and a spout. You can choose a faucet that gives you hot and cold water separately or in the single faucet models easily mix the two to give you the optimum temperature.  These faucets contain a mixing valve that blends the hot and cold water before it ever reaches your hands.
There are four kinds of valves: compression, cartridge, ball, and ceramic disc. The last three are referred to as “washerless” valves. If you are buying a modern bathroom or kitchen fixtures , you’ll be buying a faucet with one of these three valves. How come? Because most manufacturers are building washer less valves that are reliable and don’t drip. If you are into the look or feel that you need older style/designed kitchen and bathroom faucets, you will find it more difficult because they use compression valves that latter leak over time and have to be replaced. Thes e valves are the oldest technology and the least expensive. Turning the handle raises and lowers a stem. At the base of the stem is a rubber or plastic washer. It usually wears out over time and the faucet will leak. Special tools are needed to effect repairs on these types of faucets an along with the other inherent problems are more the reason to shop for better quality.
Cartridge valves, invented by Moen Faucets, enabled the invention of that single lever faucet I mentioned earlier.The cartridge controls the mixing of water temperatures. Cartridge valves last a long time, but will have to be replaced. How long they last depends on what kinds of materials are used in the cartridge. They may be plastic, metal. plaster , or ceramic which will last a long time.
The ball valve is an innovation of Delta Faucet. It is also used in Peerless and Brizo faucets and works like a cartridge. Current Ball Valves are stainless steel and nearly indestructible.
Ceramic valves are a European innovation. It’s actually two slotted ceramic disks that rest against each other. One rotates to control temperature and raises and lowers to control volume of water. This valve eliminates the rubber entirely. The water-tight seal is provided by the disks that are polished to near perfect flatness. Look for these on Price Pfister faucets as well as most European brands such as Grohe. Faucets with ceramic discs are reliable and easy to use. Faucets that use ceramic disc Valves are used in mid-range and high-end styles-faucets. If repair is ever needed, the entire ceramic-disc cartridge is replaced. A faucet with a washer less ceramic disk valve cartridge will be drip free. In fact, look for the words ‘washer less” on the  faucet packaging. How do I decide which to buy? Here are the things to consider in making your choice

.Choose your budget. Remember there are wide variables to consider when it comes to cost.  Even if you go for a more expensive European faucet, such as Grohe, my personal favorite (I drive a Mercedes why wouldn’t I want the equivolent in my kitchen?) you’ll find many deeply discounted on the  internet websites. No matter how much you decide to spend, look for the following things in a faucet

A). Ceramic or Metal Cartridge
Look for a ceramic cartridge, ball or disk valve faucet if it is in your budget. If not, look for stainless steel and brass since they also last a long time.
If in doubt about a faucet, go to the manufacturer’s web site and find the replacement parts list for your faucet. It will usually tell you the actual materials used in the valve. If not, use the toll-free number and call the manufacturer’s customer service department. If you do buy a faucet with a plastic cartridge, go ahead and get the replacement cartridge now — you’ll need it eventually.

B). How easily does the faucet operate?
I have found that in my older age some faucets just arent as easy for me to push or pull. The same can apply if you have small children at home.

C).Ease of cleaning

Nooks and crannies are great on English muffins but can make them difficult to clean

D). Say no to Plastic

 Look for brass or some metal construction and avoid a plastic on handle. Good faucets feel heavy and very solid. A Grohe sprayer, as an example feels heavy enough to be used as a weapon…LOL

E). Pay careful attention to the finish

Better quality faucets will have a more even finish and in many cases more layers of plating which adds years to the look of your kitchen or bathroom.

D). Guarantee?

What type of promises of warranty or guarantee comes with the fixture, many today do offer some form of “lifetime” guarantee at least for replacement parts.

A  Boost controller helps in regulating the amount of air pressure applied to the intake manifold of an engine.

The mechanism of boost controlling is made to best of use by modern turbo-charged engines. In these turbocharged vehicles (equipped with digital displays and modern engine management systems), the boost control mechanism employs electronic control to help in easy alteration of the boost pressure.

Manual boost controllers are, however, widely popular across the vehicle owners and come as a superior cost-effective option.

Boost control mechanism

It all starts from waste gate actuator. Attached with a boost control solenoid, waste gate actuator is the point where the boost pressure is sensed first. Evidently, if you alter the pressure on the waste gate actuator, you can effectively control the turbocharger’s boost pressure over a range of values; and program the exact boost profile required by the engine. The idea leads to a boost control solenoid valve, placed in line along with the boost sensing hose to the waste gate actuator. The boost control Solenoid Valve pulses at a controlled frequency, and thereby effectively controlling the bleeding of boost pressure from the actuator.

The higher is the pulsing frequency, the greater is the amount of boost pressure that is bled. The waste gate actuator senses a boost pressure that is lower than the actual boost pressure. And in doing so, it allows for greater boost pressure before the waste gate opens the swing valve.

What to choose – manual or electronic

In the presence of both manual as well as electronic boost controllers, it is up to you to decide which one to go for. You should get the one that fits to your budget and requires an easy installation process.

Now, be it a manual boost controller or one electronically operative; to let your vehicle thrust ahead, all you need is to get is fitted with a boost controller. And if you’re a little confused about what to go about, try surfing internet.

Your little concern towards the boost controller of your car can let you benefit from its enhanced performance.

A leaky engine is one of the most common and most irritating issues that tend to pop up for drivers. An oil leak can happen at any time regardless of things like weather or the age of the vehicle. Checking for oil leaks is something that you should do regularly, even if you have no reason to believe there may be one. Even a small leak can go unnoticed for a long time until it grows into something much more serious. It’s simply best to be safe and eliminate that possibility.

An oil leak is usually found under the front half of the car, where the engine sits. A bad leak will be noticeable just by getting down on the ground and looking under. For something smaller, you may need to get up close. Oil is pretty easy to identify. It is very thick and either brown or black. It has a certain smell that is not quite like other vehicle fluids. You will have a good idea if it’s an oil leak based on sight and smell.

An oil leak usually comes from the Valves or the oil pan. Any number of things can be the cause of an oil leak. It can happen even on newer cars without warning. Oil is essential to your engine’s ability to run smoothly and it can become an expensive problem if not dealt with right away. New cars should be covered by warranty for a random oil leak.

Once you are certain that you have an oil leak, check the dipstick. Check it like you would any other time and take note of how empty it is. This will give you an indication of how fast the oil is leaking and how bad your problem really is. A very slow leak still needs to be dealt with but it gives you more time to call your mechanic without severe worry. If you have a massive leak, call them and tell them. It may have to be towed in the worst case scenario.

If you can’t see where the leak is coming from you may have to take some further measures to pinpoint it. Never just assume that you know the exact spot and start trying to fix it. You can waste time and money this way. You need to know where the leak really is. This means getting a little down and dirty but it will be worth it when you can get to the root of the problem.

Try cleaning the engine with a good, safe engine cleaner. Washing away other dirt and grime might make it easier to see where the oil is coming out. If you still can’t find the leak, drive the car up on to safe lifts, like the ones used by mechanics or for at home oil changes. A jack is ok for lifting but you should never get under a car only secured by a jack. Safety should always come first. If you can’t get the car safely lifted, have a mechanic do it. Check for oil leaks as soon as you suspect them to avoid potential vehicle failure.

Northern Industrial Co. has developed many types of Industrial Make Up Air Units for larger industrial plants ventilation needs. An improvement in the at industrial facilities environment can produce substantial benefits in terms of increased production, reduced errors, and a decline in complaints and absenteeism among employees.

Air-Handling Units for Make-Up Air and Space Pressurization Applications have the following features:

- Outlet Temperature is usually monitored with a probe mounted near the outlet of the unit.

- Discharge Air Temperature is set at the control panel or using a remote control station.

- Gas input is “modulated” using a butterfly valve, actuator, and controller.

For Space Heating Applications, a room thermostat is used to control outlet temperature. On a call for heat, the unit will provide air heated to the maximum allowed temperature until the room thermostat is satisfied. Once satisfied, the unit will either turn off or will continue to operate at a reduced outlet temperature.

An override option may also be supplied. In this case a room thermostat is supplied in addition to the basic system. The unit is set to full-fire when room temperature falls too low.

Direct Spark units are supplied with an ignition transformer for the igniter.

Piloted Units are supplied with a solenoid-operated Automatic Pilot Valve and a small pressure regulator – around 20,000 BTU – as well as an ignition transformer for the pilot spark igniter.

Pre-purge of the system (by starting the blower for a specified time to provide a minimum air volume change) before ignition of main burner is not required by ANSI code, but is frequently specified by the user. This should be provided whenever a building contains flammable dusts or vapors that could potentially reach and collect within a direct gas-fired unit while it is idle.

To assure safe operation of a direct gas-fired heating system, a number of Safety Interlocks are commonly provided:

A. Damper Limit Switch – Dampers must be fully open before unit will operate.

B. Air Proving Switch – Located near outlet of unit to prove air flow before igniting burner.

C. Flame Supervision – Discussed above. Shuts down unit on flame failure.

D. High Temperature Limit – Signals unit to reduce gas supply when maximum allowable temperature is reached. If air temperature exceeds limit, the unit is shut down.

E. High Gas Pressure Switch – Shuts down unit to protect regulator against spikes in inlet gas pressure.

F. Low Gas Pressure Switch – Shuts down unit when low inlet pressure detected. Redundant safety device, since low flame would also shut down unit.

G. Safety Shut-off Valve – Responds to various inputs listed above – closes off gas supply.

Direct Gas-Fired Air Heating Systems are a class of equipment utilized primarily in industrial and commercial environments to provide for worker comfort. To a lesser extent, these systems are used to condition air for process and finishing applications such as material drying and paint curing.

Direct-fired pressurization units are approximately 93% efficient, with much of the available energy in the burned natural gas being delivered to the space in the form of heat. The supply airstream absorbs the heat that would be normally lost through a flue or vent pipe as in the indirect-fired configuration.
