Butterfly Valve
J-VALVES
150LB Cast Steel WCB Metal to Metal Wafer Type Lug Butterfly Valve Handle
Structural Features
Cast Steel Material: The valve body is made of ASTM A216 WCB cast steel, with high strength and good corrosion resistance.
Metal Sealing: Adopts a metal-to-metal sealing design to ensure zero leakage under high-temperature and high-pressure conditions.
Lug-Type Connection: Uses a Lug-type connection method, conforming to ASME B16.5 standards, ensuring reliable installation and sealing performance.
Double Eccentric Design: The unique double eccentric design (radial eccentricity, axial eccentricity) ensures no friction on the sealing surface during opening and closing processes, extending the valve's service life.
Fire Safety Design: Complies with API 607 standards, ensuring the butterfly valve maintains sealing performance even in case of fire to prevent medium leakage.
Anti-Static Device: Built-in anti-static device effectively prevents static accumulation, reducing the risk of fire and explosion.
Stem Blowout Prevention Design: The stem is designed with blowout prevention to ensure operational safety.
Compact Design: Small in size and light in weight, facilitating installation and integration into existing systems.
