摘要
Systems, devices and methods for regulating pressure in a blowout preventer (BOP) of a subsea well assembly. A closed loop regulator (CLR) that combines the functions of a pressure relieving valve and a pressure reducing valve into one body to control the pressure of a hydraulic circuit or a BOP mux control pod. A closed loop servo valve controlled proportional electrohydraulic reducing valve is used to allow continual variation of the pressure set point for the downstream circuit. If the downstream pressure exceeds the set point by a predetermined amount, the pressure relieving valve vents the pressure to the reservoir or atmosphere.
