Feature:
1. Apply to horizontal installation
2.Simple structure design,and easy destuffing before welding
3.Built-in spring damping mechanism,to make the piston check valve can be installed in a pressure buffer, such as the exhaust pipe of compressor
4. The piston adopts the principle of pressure drop braking to realize one-way flow,can prevent the refrigerant condensate from the high temperature evaporator to the low temperature evaporator
5.Provide a variety of diameter size connections
1.Compatible with all CFC, HCFC and HFC refrigerants
2.Environment temperature range: -50℃~+80℃
3.Working temperature range: -50℃~+120℃
4.Max. working pressure: 42 bar
5.Max. proof pressure:63 bar
