Parameter

Wafer Butterfly Valve -LWBV-11 ,is a normal type of butterfly valve - Handle Type Cast Iron Valve Body

CF8 Disc Wafer Butterfly Valve.

Cast iron Valve body and soft rubber seat are adopted with split design for easy maintenance and replacement.
After maching of valve body, because of without lining rubber, to avoid the pressure deformation of the lining

rubber.Small torque of butterfly valve. Easy to open and close.

3.Valve stem and valve body are equipped with 4 oil proof bearing,which is benefical to stem support.the

the shaft from handle to the bottom of valve .let the valve can bear big pressure.

4.After quenching and tempring process ,the pin material of butterfly valve has high strength and high corrosion

resiatance ,and the connection is more safe and stable.

5.A Non-Pin stem adopts an anti-exit structure ,spring+U type card structure are used in the upper part of the

stem,which can not only compensate for installation errors,but also prevent the stem from loosening.

Advantage

1. Small and light, easy to disassemble and repair, and can be installed in any position.

2. The structure is simple and compact, the operating torque is small, and the 90-degree rotation opens quickly.

3. The flow characteristics tend to be straight, and the regulation performance is good.

4. The connection between the butterfly plate and the valve stem adopts a pinless structure, which overcomes possible internal leakage points.

5. The seal can be replaced, and the seal is reliable to achieve two-way sealing.

6. The butterfly plate can be sprayed with a coating layer, such as nylon or PTFE, according to user requirements.

7. The valve can be designed as flange connection and wafer connection.

8. The driving mode can be manual, electric or pneumatic.
