Danfoss Type NRV Check Valve 1/4'' to 7/8'' Straight-way Solder ODF
NRV and NRVH refrigeration check valves can be used in liquid, suction and hot gas lines in refrigeration and air conditioning plant with HCFC. HFC and HC flammable refrigerants. The valves ensure the correct flow direction and prevent back-condensation 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.
