Danfoss Check Valve
NRV and NRVH can be used in liquid suction and hot gas lines in refrigeration and air conditioning plants. The valves ensure the correct flow direction and prevent back-condensation from a warm part of the system to the cold evaporator. The hermetic tight design of solder versions meet the environmental demands for today and future. 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.
