1/4" NPT Green Momentary Push Button 3 Way 2 Position Pneumatic Control Mechanical Valve,13mm Thread 2 Position 3 Way Manual Control Mushroom Push Button Air Pneumatic Mechanical Valve

Purchased this valve in the hope of using it in back pressure more ... ie reversing the cyl and pressure connections. This did not work ... as it is a $10 valve. However it did work nicely when employed as designed, ie pressure on pressure, cyl on cyl, etc. Low loss and seemingly good flow. Would purchase again -- in fact I did.
