API Standard Bronze C95800 150LB Wafer Type Double Disc Check Valve
Design Features
Material:
Valve Body: ASTM B148 C95800 bronze, which is suitable for medium and high-pressure environments.
Valve Disc: ASTM B148 C95800 bronze, with good corrosion resistance and mechanical properties.
Connection Method: Butterfly connection, which complies with the ASME B16.47B standard, ensuring a reliable connection between the valve and the piping system.
Operation Mode: Automatic operation, without the need for external power. It automatically opens and closes relying on fluid pressure.
Double Disc Design: The valve discs automatically open under the action of fluid pressure and automatically close after the fluid passes through to prevent the backflow of media.
Spring-assisted Closing: Equipped with a spring-assisted closing mechanism to ensure quick and reliable sealing and reduce the water hammer phenomenon.
Fireproof Design: It complies with the API 607 fire safety standard, ensuring the sealing performance of the valve under fire conditions.
Sealing Materials: The valve seat uses PTFE or other high-performance sealing materials, which are suitable for a variety of media and temperature ranges.
