Danfoss Check Valve - NRV12S 1/2" Solder - NRV12S

NRV / NRVH, Check valves

NRV and NRVH check valves can be used in liquid, suction and hot gas lines in refrigeration and air conditioning plants with HCFC, HFC and HC flammable refrigerants. Special versions, with a max. working pressure of 90 bar / 1305 psig are available for CO2 applications.

The valves ensure the correct flow direction and prevent backcondensation from a warm part of the system to the cold evaporator. A built-in damping piston makes the valves suitable for installation in lines where pulsation can occur, e. g. in the discharge line from the compressor.

Benefits:

• Hermetic tight design for solder versions
• Built-in damping piston that makes the valves suitable for installation in lines where pulsation can occur, e.g. in the discharge line from the compressor
• Available in both straightway and angleway versions
• Solder versions are compliant with ATEX hazard zone 2
• NRVH type check valve is with stronger spring and it’s recommended to use for compressors in parallel (i.e. power packs) where higher level of pulsation and vibration are expected
