Introduction:
8031 series piston check valve can be used in commercial refrigeration system, civil and industrial air conditioning equipment, with the piston guide autistic seal structure.Body made by forging process, and the main body is designed with maximum flow and minimum pressure drop.
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
