Check Valve
Check valve effects seal between valve core and body by fluid pressure. It is designed and manufactured in accordance with API spec 6A. it can be used interchangeably with the domestic and overseas equipments complied with the specification of API spec 6A.
Check Valves
- Working Pressure: 2000psi ~ 20000psi
- Nominal Bore Diameter: 1 13/16″ ~ 7 1/16″
- Temperature Class: L ~ U
- Material Class: AA ~ HH
- Product Specification Level: PSL1 ~ PSL4
- Performance Requirement: PR1 ~ PR2
- Working Medium: petroleum, natural gas, water, mud, gas containing H2S or CO2
The metal-to-metal seal is between valve body and valve plug. It is attained by the pressure of medium. The higher pressure of the medium is, the better sealing property is. Valve chest can bear the pressure of pipeline at any time.
The valve body is made of the forging alloy steel. It has the strong mechanical performance and can bear high pressure. Security and reliability is guaranteed.
Instructions
According to the valve’s flow direction, install the valve body on the pipeline valve trim by the pressure upstream and downstream of the pressure to achieve movement and seal, thus the valve trim can’t be stuck.
