Small relief valve vendors?
Small relief valve vendors?
(OP)
I'm trying to find a relief valve around the .187 diameter sizing. I currently use a Lee Co. valve, but it doesn't function very well at the moment. I'm looking for at least 200 psi cracking pressure.
Thanks,
Thomas

I had the chance to develop a gas pressure relief valve for 1100 psi with less than 5% gap between the cracking and re-sealing pressures but it had larger diameter.

Can you provide more information on the circuit arrangement it was not clear form your previous post. Especially the following statement: "We pull a vacuum against the seal in the oil filling process and the valve leaks in this situation"
What kind of oil?

I'll try to clear up how its used in this application. We have a volume that has only one input to be filled and a fairly complex shape and this Lee Co. valve inserted to allow the volume to vent if the pressure exceeds XXXpsi once the system is filled and closed. But since there is only one input, you can't just pour in the oil, you have to pull a vacuum on the volume with a container of oil inline and let the oil backfill into the void. It works very well until this valve doesn't seal after it has vented once.

All fitting manufactures have this type relief valve or some even have vent valves that have high cracking pressures.
