Valve body of Pneumatic triple eccentric butterfly valve adopts triple eccentric structure with excellent cut-off performance and durability.
Features
1. Small size, light weight and excellent cutting performance.
2. The disc sealing surface is designed to be an oblique truncated conical surface relative to the disc axis, so that the disc sealing surface and the valve seat sealing surface have a certain contact angle. Wedge-shaped, and the sealing line at the longitudinal direction of the disc circumference is a quasi-elliptical curve, both of which play a compensating role for sealing.
3. When the disc sealing surface is closed, the force is uniform and the pressure bearing capacity is high; during the opening process of the disc, all points of the sealing surface are simultaneously separated from the sealing surface of the valve seat, and there is no jamming phenomenon and basically no friction. The opening torque is very small. Therefore, the cost is low, the sealing performance is good, and the service life is long.
4. Various sealing structures are available to ensure service life and reliability. Butterfly valve sealing ring has integral soft seal (PTFE, C-TFE, G-TFE), hardened metal sheet, integral + hard alloy, suitable for various working conditions.
5. It can realize two-way sealing function, which can be adjusted and cut off.
6. The actuator has low friction, high work efficiency, large thrust and good safety.
7. The design of the dexterous and combined type (manual mechanism) of the actuator can ensure random installation and flexible control in all directions.
8. Simple, eye-catching, reliable and integrated travel indication and combined installation of limit switches and solenoid valves, no external pipelines, and reduced leakage points.
9. A variety of actuator forms are available to meet different user requirements.
10. It is easy to assemble and maintain, and has a superior cost performance.
