Rubber Seal Pneumatic Flanged Soft Seated Butterfly Valve

The disc of thepneumatic soft seated butterfly valveis mounted in the diameter direction of the pipe. The disc-shaped disc rotates around the axis, and the rotation angle ofpneumatic soft seal butterfly valve在0°、90°之间。当rotation is 90°, the valve is fully open.Pneumatic flanged soft seated butterfly valveis suitable for the industries of temperature ≤120°C or ≤180°C and nominal pressure ≤1.6MPa,such as water supply and drainage,sewage,food,heating,gas,marine,hydropower,metallurgy,energy systems and textiles and other industries.

The Characteristics of Pneumatic Soft Seated Butterfly Valve:

1. Compact and lightweight, easy to disassemble and repair, and can be installed at any position.
2. The structure is simple and compact, the operating torque is small, and the 90 degree rotation is quick to open.
3. The flow characteristics tend to be straight and the adjustment performance is good.
4. The diversity of sealing materials can be selected by users.
5.The seal can be replaced, and the seal is reliable to achieve two-way sealing.
