Remote air blow off for air diaphram pumps , safety and for stalling issue .

I may have a possible solution for the stalling issue on air diaphram pumps , and It would also be an added safety measure to turn off the pump from the roof . My background is in irrigation , a large part of my fall business is blowing out sprinklers , I use a 125 cfm tow behind compressor , pushing 100 psi constant pressure. Now irrigation valves are a normally closed valve , they are rated for 125 psi . My Idea right now is theory . I have seen remotes , like the keyless remotes for cars , an irrigation valve ( old style toro 3/4 in would be best its bullet proof) and a 9 volt battery . Just prior to the air supply to the pump plumb in a tee ,it could be all on quick connects, the irrigation valve would be off that tee . Wire up the remote and battery, when the pump stalls simply push the remote , it would blow off your air pressure , reset the remote and you have pressure again. Drop the hose , push the button on the remote and you have no air pressure , the pump shuts off . I just havent had the time to find the remote stuff . The 9 volt battery will work even though the valves call for more , we do this too test them in the yard. I havent had a chance to make one as of yet , I dont have heat in my shop . This may be able to save a couple of trips back to the truck or to shut off the pump quickly. A remote could probably be wired in to the electric pumps to turn them off in an emergency. Irrigation valves are about 20 bucks retail , the remotes cant be that expensive I would think . Matt
 
There are a couple older threads where Tony s. from Sonitx bought a remote for the pressure washer for $79 and rigged it up so that it would activate the choke, turn the machine on/off and switch the burner on and off. He even has a couple youtube videos, one is showing the remote working from 405' away from the machine and the other is installing the remote onto the pressure washer. You just have to do some searching for the threads, they are here.
 
I read some of those before I posted , what I am trying is basically a remote pressure releaf for the supply air on dual diaphram pumps , 1 so that if the pump stalls you can unstall it from a distance , second if you have a problem , you can reduce the air pressure to the pump to the point it wont operate . Stopping the flow of material . I am gong to play with the idea some more this week .
 
Sounds like a great idea. What you are looking for is a remote that will connect to an air solenoid. The solenoid will act like a light switch and should be normally closed except when you send a voltage to energize it. 12 volt would be easiest.

I use a remote (not cheap $1500 - and I do not know if they are still in business) to control the injection of chemicals to my pressure washer injectors & for starting my pressure washers from up to 300' away.
 
The valve is easy , I have cases od irrigation valves , they hold up well and the pressure is no problem and they are normally closed. I just need to find a cheap remote .
 
Great , thats the ticket . Yes the compressor wit run at full speed , but thats no more speed than it runs when you start it , top speed is governed , and or set by your throttle . It can run like that all day , that isnt a problem .
all I want to be able to do is dump the air for a short period of time if the pump stalls , or to dump the air if there is a problem like dropping the wand while its open , or a hose breaking . It will reduce the pressure fast and stop the pump till I get to the trailer to shut it down .
