CV One Way 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.
