Duplomatic MRQA-5/1 accumulator charging valve, NG6 (CETOP 3), with 50 to 210 bar setting range.
The MRQA-5/1 is a pressure relief valve with automatic unloading, for circuits with an accumulator. On reaching the set value it lets the pump unload freely to tank, and puts it back under pressure when the circuit drops to 78% of that value. Meanwhile the accumulator holds the pressure.
Without a check valve, the accumulator would discharge through the open valve. Make sure the circuit already has a check valve between the MRQA and the accumulator; if not, choose the MRQA-5/1/C.
