sprinkler valve question

Unread postAuthor: )DEMON( » Thu Apr 27, 2006 3:44 pm

when you trigger a modded sprinkler valve dose it only close after it has let out all the air out of the chamber(if you had a pneumatic)or dose it let a bit a of air out then close ? i want to know if you could make it a semi automatic valve?

(sorry if it sounds like i dont know what i am talking about because i really dont know allot about this)

The sprinkler valve will stay open as long as the blowgun trigger is held down(and air is flowing to the valve, otherwise it doesn't matter), once the trigger is realeased, then the valve closses. If your semi-auto plan involes simply a quick disconnect on the chamber then shooting by pulling the trigger for everyshot, it should work.

Some air will be left, but not enough to get a second shot off.

because when the blowgun is on the diaphram cant reseal , but if the blowgun is off, the other side of the sprinkler valve (pilot) can build up pressure pushing the diaphram back down onto the sealing surface and closing the valve. :D

this will make an exellent paintball gun but where i live sprinkler valves cost R154 (Rand) ,small fire extinguishers cost R160 ,Im not sure about the blowgun and all the other bits and peices could cost about R50 so that all adds up to be R364 + . it is about R6 to $1 (USA) so R364 =$60,66,my allowence is R100 a month but my birthday is in June(lots more money)
Final conclusion; CRAP I wont be able to do this as quickly as i wanted. :(
