Model CV one-way valve is used on the piping of liquid, suction gas or hot air on the freezing, cold storage and air conditioner units.
The valve seat and seals of Model CV one-way valve have excellent sealing performance.
For Model CV one-way valve. Both threaded and welded connections are available
 
 Features
Ensure one flow direction and avoid reversal
With the built-in damper and could be mounted on the piping with pressure pulsation.
Prevent refrigerant back flow from high temperature evaporator to low temperature evaporator.
Applicable to the refrigeration unit in parallel with compressor.
Both direct flow type and right-angle type are available.
