Parker 900409P Regulator Els PW 17895 while the check valve preventsThe Parker 900409P Regulator, specifically the Sporlan CRO 6 0 60, is a high performance crankcase pressure regulating valve designed to protect compressor motors from the excessive torque caused by high suction pressures. As a direct acting, adjustable suction line regulator, it effectively throttles vapor flow from the evaporator when pressure exceeds the setpoint, which typically occurs after a hot gas defrost cycle or prolonged shutdown.
