AWP Constant pressure valves RVR

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 high compressor units during the starting phase and does not open before the complete oil circulation has been 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, as well as with customer-specific inlet and outlet connections.

Technical features:

• Available in steel or stainless steel
• Selection of body material as per German DIN EN12284, AD2000 Series W
• Working media: Refrigerant according to fluid group 1+2 of pressure equipment directive(PED) 97/23/EG.
• Mounting position: horizontal and vertical with upward flow direction
