Solenoid Valves are the most commonly used valves in process automation. From basic water shutoff valves to severe service petrochemical refining applications. Unfortunately, they are too often misapplied and cause process inefficiencies, upsets, and shutdowns. This program is intended to provide a comprehensive overview of the criteria used to properly size & select solenoid valves for both new and seasoned practitioners.

Instructor Ray Herrera is President of The Valve Shop, Applied Valves & Controls, Inc. He has extensive experience with sizing & selecting valves for process control and automation. Prior to founding The Valve Shop, Ray worked as an Inside Sales Engineer and Field Sales Engineer for major Manufacture Rep Companies of Control Valves, Instrumentation, and Process Control products.

Next gun will be 1000psi using a disposable welding bottle as gas source.

Here is a bb gun that i made from scratch, its composed of a homemade Solenoid Valve that is released by a capacitor bank discharging through the coil. I run it at 250psi but it can go over 300psi. This is just a prototype and is not yet portable but is extremely powerful for an airsoft gun as it can put dents in dumbells with only 0.12g bb’s. The solenoid is only small and requires a lot of capacitors to power it, the next one has a larger coil (over 5 times bigger coil) and is designed to use less power to trigger and therefore less capacitors.

This is only part one, in part 2 i will show the bare workings of my next bb gun, along with some speed tests and in part three i will show the gun fully completed, speed tests and accuracy. The gun in this video does not have any body and is breach loaded, the final gun will automatically reload, have interchangeable barrels and will also be durable.

Note: Most of the really powerful bb guns are not portable because they usually run off a compressor, this will totally be portable in the final product and nothing will be taken from another gun, its all going to be homemade.

Vinyl Siding doesn’t require high pressure to clean. Down-streaming the right detergents and low pressure is all that is needed. This example uses a ball-valve to apply detergent and to rinse.
