CV and CVRH type check valves are used in liquid, suction, and hot gas lines of refrigeration, freezing, and air conditioning systems.

CV and CVRH type check valves can provide oversized connections to increase the flexibility of check valve applications.

Application scenarios:

• Cold storage rooms

• Coolers

• Heat pumps

• Refrigerated transport (cold chain)

• Suitable for fluorine systems, fluid temperature range from -50 to 140°C

Product advantages:

• This valve ensures a unique correct flow direction.

• Available in straight-through and angle valve forms, with good sealing at the valve seat and seal.

• Prevents refrigerant from flowing back from the high-temperature evaporator to the low-temperature evaporator.

• Built-in shock-absorbing piston, can be installed in places with pressure pulses, such as the discharge pipe of compressors.

• CV check valves are available with threaded and welded interfaces.

• CVRH features a reinforced spring with △P=0.3bar, suitable for refrigeration systems with parallel compressors.
