I think this is where an electric valve and a controller would be beneficial rather than a manual valve or pressure switch.
The electric valves are only closed in one direction when off enabling it to fill and hold until switched on by the user or a pressure switch, unlike the the manual valve which must be opened to fill and/or empty.
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.
