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.
Features and Benifits
Ensure correct flow direction
Available in both straightway and angleway versions
Prevents back-condensation from warm to cold system part
Solder versions are compliant with ATEX hazard zone 2
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
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
Oversize connections provide flexibility in use
