pilot valve for 300 psi?

Unread postAuthor: GustavssonB » Sun Oct 21, 2012 1:08 pm

Were can I find a small pilot valve that I can use to trigger my QEV.
I want it to be able to work at 300 psi (20bars) pressure.


The current valve I´m using is a simple ball valve, witch I think is to big and it doesnt feel as a trigger.

check ebay or mcmasters



personally id say go with a pneumatic relief valve, they are aluminum and will launch golf balls out of sight in seconds!and with these valves its already piloted!


these valves im talking about are inch and half

Is this gun connected to a constant air source? If so, the MJVO-3 has been proven at those pressures. A slide valve is always good too.

If you have a "fill here and shoot over there" setup then you can use a pistol-grip blowgun for that trigger feel. What size QEV is this? A good modded blowgun can handle a 3/4" QEV with no trouble.
