All About Valves

Archive for August, 2009

I am building a private unmanned aerial vehicle and I need to figure out what i need to operate an on/off Solenoid Valve from a far distance. As of right now, testing will begin around a 1 mile range. I am a mechanical engineer and my electronic knowledge is not extensive. thanks for any help in advance.

I don’t know what your budget is. You could use a RC radio control and the switching circuits, perhaps.

Otherwise, a small low powered transmitter and receiver with a DTMF encoder / decoder (to avoid spurious triggering).

A Honda dealer did a diagnosis today and found it stuck in the open position, resulting in a fast idle in slow- speed driving. It’s not noticable on the highway. Could this be a safety problem on the highway, or in the city? She wants to start an 850 mile trip home tomorrow (Sunday). A replacement valve was not available today. I told her to wait till Monday,and have a repair shop look at it. What should she do?

It should be replaced. They don’t cost that much. It only causes high idle and won’t affect anything else. A shot of carb cleaner might solve the problem if it’s just dirty. Stay away from dealers unless you are sure of their work. The dealer should have cleaned it for you.

Hi,

the trim of some ball valve is specified as "CS ENP".
what does ENP stand for?

thanks heaps!

99.9% sure about this.

CS- Carbon Steel
ENP- Electroless Nickel Plated

We washed it out with gas and it seems clean, but once the engine is under preasure the oil leaks out.

I never heard of a small engine with a PVC valve, what kind of engine is it? Are you sure it’s not blowing oil out of the oil breather hose? If it is, either it is overfilled with oil or the piston rings are worn out or cracked.

I have a washing machine problem. When it starts letting cold water in, it comes back out the hot water valve and out the hose, leaking out. Is this just because the hot valve is broken and stuck open? Should there normally be backflow of cold back up the hot channel? Or is the likely some other problem like a blockage or something..?

Thanks!
There is a hose on the hot water, but maybe it has deteriorated, as water leaks out the end. Should the inlet valve let water out like that, or should it normally be closed?
How can I turn the valve on or off? The valve is electrically controlled by the machine. Does the hot inlet valve require pressure from the water tap being on to stop back flow out the valve?

This is a common situation. Nothing is broken. You should put a hose on the hot side unless you have no hot water to tap from. Then put a cap so that the water will not flow through.

Then wash away!

If your faucet continues to drip and waste water when turned off then you have a problem that is all too typical. In today’s article we will give you the information that you need to know in order to fix this common household problem.

There are several types of faucets found in homes today, including the washer type, the washer-less type, the spring-and-valve type, and the disk type. The repair procedure differs for each type. Because replacement parts vary so much, it is best to find a hardware in your area that has replacement part reference books and to work with them to find the parts you need. When possible, try to determine the manufacturer of the unit before you go to the hardware store, and take the old parts along with you for reference.

What to do: If a faucet begins to leak, never use excessive force to try to close it because that will only cause damage. Nearly all faucets can be taken apart to replace defective parts. Before beginning to work on a faucet, turn off the stop valves on the hot and cold lines. If you don’t have stop Valves, you will have to turn off the main water supply valve and work on the faucet when the rest of the home can get by without water (or have a plumber do the work).

With washer-type faucets, dripping water is often caused by worn out washers. Replacement involves taking out the screw in the handle (which may be covered by a decorative cap), taking off the handle, loosening the packing nut, and removing the spindle and washer assembly. A screw holds the washer in place. Replace it with the correct-size washer and reassemble.

Note: If washers must be replaced often, it may be a sign that the faucet seat is worn. If the seat is replaceable, install a new faucet seat insert, or reseat (smooth the seat with a seat dressing tool). If a worn faucet seat is not removable, the only option is to use this tool. For other types of faucets, consult product sheets, detailed how-to books, or your local parts supplier.

If the faucet that drips is more than 5 years old, you may want to consider replacement rather than repair – unless the original is a high-quality faucet. More expensive, quality replacement faucets are generally worth the money; they can last up to three times as long as inexpensive faucets, saving both replacement and labor costs.

Tip: If there are no stop valves near the fixture where a faucet must be replaced, consider installing new stop valves at the time of the replacement. They will allow you to isolate the fixture and still have water throughout the rest of the house the next time the faucet needs attention.

Faucet Handle Leaks

When water comes out along the handle of the faucet when it is turned on, you have yourself a faucet handle leak. Some faucets, usually old-style units, use either a washer or packing (which looks somewhat like greased yarn) to keep water from escaping along the spindle. In this case, the problem will most likely be with the washer or packing material under the packing nut, not the faucet’s washer .

What to do: If water is leaking around the handle area, remove the handle and try to tighten the packing nut. If this doesn’t correct the problem, remove the packing nut. If there is a washer under it, replace it. If there is no washer, you will need to unwind the old packing and replace it. After wrapping the spindle with new packing material, replace the packing nut. The packing nut will compress the packing material in place. Replace the handle and turn the water back on at the shutoff valve.

Mixing faucets, which are used on sinks, laundry tubs, and bathtubs, consist of 2 separate units, with the same spout, that need to be repaired separately. Most packing nuts may be loosened with an adjustable wrench, and most will loosen by turning counterclockwise. (Caution: Avoid using excess pressure with wrenches because it can cause damage and create the need for new parts.)

Tip: When buying packing material, ask your supplier to see any improved versions in stock. Some newer, nylon-coated materials help faucet handles turn easier and last longer than the older packing materials do.

Roush has recently introduced the first dedicated propane-powered F-150 pickup truck which is equipped with an advanced liquid propane injection (LPI™) system. The Roush F-150 LPI™ is designed and manufactured to operate solely on propane while providing the same horsepower, torque, and drivability similar to an F-150 equipped with a gasoline powered 5.4 liter, 3 valve Triton™ V8 engine.

Roush has already started taking orders for the propane-powered F-150. And not only that, the 2007 model year truck may now be ordered, delivered, and serviced through a nationwide network of selected Ford dealers.

The Roush F-150 is available in Regular Cab, SuperCab, and SuperCrew cab styles with XL or XLT trim and the full range of bed lengths. The LPI™ option also includes dedicated propane fuel lines, fuel tank, and fuel rail assembly. The vehicle’s computer has been fine-tuned to provide optimum performance and fuel economy.

The base LPI™ option is priced at $6,500 and includes a one-of-a-kind toroidal fuel tank, mounted in place of the underbody spare tire. For customers who want to increase range, a 50 gallon, in-bed fuel tank is being offered as an option.

The Roush F-150 LPI™ has made its debut at the recent NPGA Southeastern Convention and International Expo in Atlanta, Georgia. The conference was held last April 14 to 17 and was considered as one of the largest propane industry conferences in the United States. According to Tom Arnold, Director, Alternative Fuel Products for Roush: “Aside from its superb engineering, this vehicle is right here, right now! It is an alternative fuel vehicle that has an established refueling infrastructure to support it. This vehicle will have a positive impact on reducing emissions and our dependency on foreign oil.”

The LPI™ fuel rail assembly is made up of two billet aluminum propane injection fuel rails, an insulated cross-over, a combined pressure/temperature sensor, and a service port that provides data to the engines’ computer resulting to a more precise fuel control at the intake port. Roush also make use of the fuel injection and fuel storage systems supplied by CleanFUEL USA and ICOM, Italy. By the way, LPI™ is a registered trademark of CleanFUEL USA.

The standard toroidal fuel tank and optional in-bed fuel tank include a special high flow fuel pump, dual filters, and the required control Valves needed to run the engine. The tank also contains the fuel sender and electronic auto stop fill system. The fueling is done through the fuel filler door, and an automatic stop fill device that prevents overfilling. This process enables the vehicle to be filled without using the bleeder system that vents propane vapors during filling. Fuel is also filtered before it is made to enter the tank.

Vehicle start is controlled by a one-touch system to provide the driver with the fastest possible start and the least possible emissions. The OEM engine control is used with unique calibration values to suit the changes in properties from gasoline to propane. The maintenance schedule for the Roush F-150 LPI™ is similar to that of a regular gasoline engine schedule only without the special oils or change intervals required. The Roush F-150 LPI™ just like any type of truck may have its looks further enhanced with the addition of hood shield. Hood shields are the latest in add-on trucking accessories. A hood shield truck is perfect for any type of truck since it doesn’t bend, flex, or flutter even when traveling at high speeds.

The PERC short for Propane Education and Research Council awarded the contract to Roush in February 2006, and Roush designed, manufactured and brought the truck to market in only 14 months. Brian Feehan, managing director of engine fuel programs for PERC, “Roush has an unparalleled reputation for technical expertise, quality and value. It is because of this expertise and experience that we chose Roush to develop this vehicle.”

The all-new 2008 Subaru Tribeca stirred the North American crowd at the recent 2007 New York International Auto Show that took place at the Jacob Javits Convention Center in Manhattan. The 2008 Subaru Tribeca “features more style, more power and improved efficiency”, according to the Japanese automaker.

For the 2008 model year, Subaru gave the Tribeca a new bold exterior styling with a larger and taller front grille that is now integrated into the vehicle’s front bumper. The grille features a chrome spread-wing design and Subaru star cluster badge. The 2008 Subaru Tribeca also comes with a new hood design with raised line, deeper front valance, new headlamps, functional rear three-quarter windows, new larger side-view mirrors, powerful fender flares and wheel form, new rear valance below the tailgate, and a new wider tail lamps.

Inside the 2008 Subaru Tribeca, comes a sophisticated twin cockpit design featuring sculpted dashboard with aluminum-look trim. Interior lighting provides a sophisticated touch and elegant feel including electroluminescent dials illuminating the front and rear footwells, center console, and cup-holders. The vehicle’s center console consists of driver controls and information like audio system, clock, fuel economy, outside temperature, and navigation system with a seven-inch touch screen. Moreover, a rear-seat DVD entertainment system is also available as an optional component. As a sport utility vehicle (SUV) model, the 2008 Subaru Tribeca features a comfortable passenger space as well as luggage room. The 2008 Tribeca features a 7-passenger configuration with a standard 50/50 split fold-down third-row seat and auxiliary rear cabin air conditioner to enhance the interior comfort for its occupants.

A host of active and passive safety systems for the 2008 Subaru Tribeca are available as standard equipments. These include a Ring-Shaped Reinforcement Frame Structure, occupant-sensing, dual-stage driver and passenger airbags, seat-mounted side impact air bags, and standard side curtain air bags for the front and second row seats.
