Tying an electric valve into either a standalone or arduino (etc) and say comparing oil pressure vs rpm vs accumulator charge pressure to determine when to open the valve would give the benefit of fast reaction like a simple pressure switch, but without dumping oil every time pressure drops because rpm did.

Link?
All the solenoid valves I was looking at were either NO or NC so they won't fill unless triggered or would need a one way bypass to refill the accumulator. Most also had buna orings and seals so not good for high enough temperature. Need either viton or epdm.
