    Drop impulse shock wave

    Hi, I wasn't sure where to post this but since there are shock waves involved I thought i would start here although it may be more of a physics question. I am doing some trigger design on a paintball gun and want to try and do some rough drop scenario calculations. The main component a am...

    Fast acting Valve to deliver charge of air

    Thanks Compositepro but i haven't been able the thread you are talking about. I have found high speed valve threads to recreate water hammer but i think my application is quite different. Also i have talking about steel punch design but using conventional hydrolic presses. Compositepro could you...

    Fast acting Valve to deliver charge of air

    Hi guys I am designing a punch device the can impact and punch through steel. I need a very high speed, high power actuator of some sort. I am thinking of using high pressure air with some sort of high speed actuating, high flow impulse valve. Not wanting to reinvent the wheel I am looking...

    Pneumatic slide valve

    Thanks Again for the input Hydtools. I got hold of some viton 85A Orings. This has stopped the Oring popping off but I am still seeing some damage to the Oring. Cutting and then eventually breaking after around four cycles of the valve. I have asked around here locally for some advice on the...

    Pneumatic slide valve

    Hi Ted, Thanks for the reply. Making at least the front seal static i think would be the way to go but i also think it would also make the oring hard to install. I could try a sleeved bore where oring could be pre-installed but i have very little wall thickness to play with and i think it would...

    Pneumatic slide valve

    Hi guys, I am having trouble with a pneumatic valve i have designed. The operating pressure is 500psi and running dry air. Please see attached for the valve CAD snapshots. The scale is rather small, the smallest Oring is ID-4mm CS-1mm. The first iteration of the design i had the o-rings running...
