I need a fast acting electric ball valve. Faster the better. Would need to be able to withstand about 130 to 150 psi, higher would be better. Probably 1.5 to 2 inch diameter.

I'd be open to different kinds of valves. Speed of opening is key. Dont need adjustability. 100% closed and 100% open is all thats needed.

Whacha got?

Would prefer dc.

Yeah, I don't think you want a ball valve but a solenoid valve.

Ball valve is going to take time to rotate open to close. Solenoid will be be normally closed or open, depending on what you buy, and go the opposite almost instantly in the ones I have seen anyways.

I have electric ball valves on my van for fresh and gray tank dump and also to open and close the propane bottle. Takes about 15 seconds to completely cycle open to closed and vice versa. Doesn't sound like that is what you want. US Solid was the brand name and they make solenoid valves as well.

The one I linked takes .7 of second to fully open and fully close.

When water is running it has a force, when that water is suddenly stopped all of that force has to go somewhere and if the plumbing can't handle it, the plumbing will be damaged or even explode.

Water hammer thing depends on whether you're looking to release pressure or suddenly build it.

If you've got 150 psi behind a tennis ball, yes you can vent that shit instantly and have a good time. If you have free flowing water that will have 150 psi behind it when you close the valve, yes that one you need to worry about.

ahhh, yeah.

This will be up to 175 psi air pressure pushing heavy things out of a steel tube.
Marbles, ball bearings, roller bearings, the pivots out of semi brake shoes opposite of the s-cam (whatever those are called), taters, tomatoes, corn cobs....might even try out a pinion gear. Probably make some sabots out of expanding foam.

You will need a very good release Agent on that foam. It likes to stick to itself after you’ve already sprayed it.

I might have air valves leftover from the tire plant
 
What you need is a quick dump valve. Has a small pilot and a big bore valve. When the pilot is vented / pressurized (depending on the type of valve), the big valve quickly opens. A good source would be from a tire mounting machine. They have a volume tank on them with a quick dump valve to blast air into a tire to pop the beads on stubborn tires. They often are controlled by a foot pedal pnumatically whereas the hand held portable units use a 1/4 turn manual ball valve. I have one sitting on the floor in my shop.

If you are being serious then go to the golf ball launcher thread, you need a tire cheetah from Amazon with a diaphragm valve
