Something about the valve bonnet might be 'off'

It may be a fluke..... someday.... for now it works and has worked perfectly, daily for 4 days... and counting... I bet there was a clog that cleared up on it's own or some other coincidence I am not aware of. Nevertheless I tried raising the pressure and it just stops working every time. I agree there may be some reason that the pressure is affecting the operation of the valve. It only happens on one of the 6 valves. By the way Superior recommends 40 - 60 psi on their troubleshooting literature....

Solenoid operation is pressure dependent - increase the supply pressure, and the solenoid requires more oomph to operate the valve. Poor solenoid operation with multiple solenoids would suggest an electrical problem, since a working solenoid on a working valve will have no problem opening the valve, as long as everything else is up to spec.

A superior brass inline valve is rated up to 200 lbs of pressure... I'm predicting your fix is a fluke and temporary...

Guys. Thank you for your suggestions. None of them worked although it helped me get to the answer. When I adjusted the pressure regulating valve I have on the line, the valve began to work. There was too much pressure on the line. I reduced it to about 40 psi and it started to work just fine. Something that might help others to know. I just happen to have too much pressure and I put in a regulator some time ago. Maybe there was some dirt in the line or some valve hole that unplugged and changed the pressure or volume of water. Anyway that is the solution to keep in mind. Any questions anyone has they can email me at eddielopez2114@yahoo.com

A simple experiment - remove the plunger from the solenoid assembly

Change the bottom half of the valve as well. Problem solved.

The body has a small hole that the solenoid sits over. It is clear. No obstructions there. Is there something that could be preventing the solenoid from lifting while the system is under pressure. When testing it I can see it will pull the spring loaded plug into the stem. Yet I think it may not be doing so when the water pressure is added to the equation....

Probe the water passages in the body of the valve, and you may find a blockage.
