Butterfly Valve
J-VALVES
Structural Features
Cast Steel Material: The valve body is made of high-quality cast steel, which has high strength and good corrosion resistance, suitable for various media and working conditions.
Triple Eccentric Design: The unique triple eccentric structure ensures that the butterfly disc has almost no friction with the sealing surface of the valve seat during the opening and closing process, reducing operating torque while improving sealing performance and service life.
Turbine-Operated Mechanism: Equipped with a turbine-operated mechanism, it enables labor-saving and stable operation, suitable for manual operation. Meanwhile, pneumatic or electric actuators can be optionally equipped to achieve automated control.
Replaceable Seal: The sealing material is replaceable, with reliable sealing performance to achieve zero leakage, ensuring the long-term effective operation of the valve.
Automatic Centering Function: The butterfly disc is equipped with an automatic centering function, realizing a slight interference fit between the butterfly disc and the valve seat to further improve sealing performance.
Valve Stem Sealing: The valve stem adopts a multi-layer sealing design, which is not easy to deform, avoiding the common problem of valve stem leakage and ensuring operational safety.
Flanged Connection: Complies with ASME B16.5 and ASME B16.47 standards, ensuring convenient installation and reliable sealing.
