Product Details
Danfoss Type NRV Refrigeration Check Valve Straight-way Flare
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.
