check Valve

 

· 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 reveral.
· 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.
