can a sprinkler valve release on it`s own ?

Unread postAuthor: rgormley » Mon Oct 09, 2006 6:17 am

just wondering if the 24vac sprinkler valves could release by themselves

ie: due to some sort of internal air leak, mechanical failure?
Or pressures getting to close to the working pressures of the sprink

When we load, then pump up the chamber and then point and shoot.

I would hate for the valve to let go before i had it pointed away at my targets

Any idea how reliable they are? Has anybody had one go of unexpectedly

of course theres always the chance of a freak accident, but I've never had it go off without touching it. However i have accidentally bumped the trigger when pumping before.

Here's a tip. Dont pump the chamber up after you've loaded the breech. If I'd have done that , Id be dead right now. :D

hhhmmm so your saying it`s safer to pump them load projectile?

I would have felt safer not sticking a projectile down thebarrel with a chamber fully of air?


thats the "nasty" end and i would not fancy placing the spud or whatever in barrel if there is a chance if could go off.

prefer to load and have the thing pointed away from me THEN pump it up,

at least if it does go off without my controll the nasty end will be away from me and hopefully pointing down the backyard/garden somewhere

Dunno what do you think......

Sprinkler valves are very reliable, I've never heard of one failing prematurely. As for loading, I always load after I pump, but I do have a breech loader that shoots marbles. If you are shooting spuds and loading from the muzzle I would probably load first and make sure that the cannon isn't pointing anywhere you don't want to be damaged/destroyed or at anyone.

The only non-destructive way I can think of a sprinkler valve failing and firing on its own (more or less) is if a modded valve using a hose connection to a blow gun managed to have the hose come loose from its fittings, releasing the air inside it and triggering the valve.

As others have noted sprinkler valves have held there reputation of being very reliable, and safe. Sometimes if the projectile is loaded prior to loading, when the chamber is filled the valve will honk. I once had a valve I tested that honked only once it had reached 60 PSI. That can be dangerous. Besides that, the only other possible scenarios I can think of is the diaphram rupturing, or springing a leak of >1/16" diameter hole.

If you're all that worried about it, put a 2" ball valve behind the sprinkler for a safety. Open it before firing...

Peace,
