Looking for a Normally Open Solenoid valve that is compatible with water 2

Hello. I am looking for a Normally Open Solenoid Valve that is compatible with water, and its operating pressure is at least 1500psi. I am using this for an automated pump system project. The pumps maximum pressure it can output is around 1500psi so I will need a solenoid valve that can withstand that pressure and also be compatible with water. It needs to be normally open because this valve will be used as a safety pressure relief valve.

I was using a directional control hydraulic valve before, but I guess it was not compatible with water because after a couple of days the valve got stuck shut. The only valves I could find online were normally closed, all the normally open ones I found were either not compatible with water or have a low operating pressure.

@IRstuff I have been looking for weeks on google and no luck. All the normally open ones are under 1000psi. Calling every person and company I can, there are normally closed versions that work at those psi's but I could not find any that are normally open above 1000psi. Thanks for the kind words you are so helpful
 
I have serious reservations concerning the wisdom of using an electric valve "as a safety pressure relief valve".
Yes, it looks fail safe on paper, but after a lifetime spent trouble shooting systems, I have seen too many times when a component failure led to a component NOT being de-energized when it was expected to.
Specifically, I have seen more than one pressure switch fail closed due to wear and mechanical failure of internal parts.
If your relief pressure must be adjusted for different test, I hope that you have a back up, mechanical PSV.
You have already discovered one failure mode.
"because after a couple of days the valve got stuck shut."
There may be other failure modes of an electrically controlled PSV system, as yet undiscovered.

Not just a good idea;
It's the LAW!
 
Yes, there is an adjustable mechanical relief valve in the system that can be adjusted from 0 to 2000psi. So if any overpressure does happen, this valve will open directing flowing to the tank.

I found out that it was my fault, the valve was not rated to take water because it was not corrosive/rust resistant so the water made it stuck shut. Thankfully I am in the testing phase and will be for a while.
