Product information
NRV and NRVH check valves can be used in liquid, suction and hot gas lines in refrigeration and air conditioning plants. 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 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.
