Oil Pressure Valve

Oil pressure valve is used in a Low Pressure Oil Manage- ment System. The function of a Pressure Vent Valve is to maintain a positive pressure in the Oil Reservoir above the compressor crankcase pressure It is used to vent pressure in the oil reservoir while still maintaining a posi- tive pressure differential between the reservoir and the compressor crankcase. This positive pressure ensures an adequate oil supply to the oil level regulators. The reservoir pressure valve is piped to suction pressure. 

APPLICATION

Protection against possible overpressures compared to the design parameters set for commercial and indus- triel refrigeration systems, heat pumps, air condationers (condenser, compressor, oil reservoirs, collectors, liquid receivers) and similar pressure vessels. 

Suitable refrigerants:

•  HCFC (R22)

•  HFC (R134a, R404A, R407C, R410A, R507)

•  HFO and HFO/HFC mixtures (R1234ze, R448A, R449A, R450A and R452A)

For specific applications with refrigerant fluids not listed above, please contact GVN Technical department.

ADVANTAGES

* RELIABLE: the PTFE gasket does not stick to its seat and maintains the calibration of the device over time.

* SAFE: they are 100% tested on a dedicated helium system.
