NRV12-16S,NRV22-28-35S,020-1021 Danfoss Check valves

NRV12-16S,NRV22-28-35S,020-1021 Danfoss Check valves 

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.

 Ensure correct flow direction
y Available in both straightway and angleway
versions
y Prevents back-condensation from warm to
cold system part
y Hermetic tight design for solder versions
y 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
y 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
y Oversize connections provide flexibility in use
