  • product introduction:RVR Constant Pressure Valves Constant pressure valves with check valve function. The constant pressure valve with check valve function (RVR) is the successor of the constant pressure valve (RVD). It increases the pressure on the discharge side of the compressor during the start-up phase and open only after the oil circulation is completely secured. This prevents the refrigerant from condensing in case the compressor shuts down. The integration of the check valve function is a new feature compared to the previous constant pressure valve. The RVR is available in diameters of DN40 to DN150, and with optional customer-specific inlet and outlet connections.
