WCB Body Wafer Type Butterfly Valve

Wafer Butterfly Valve -LWBV-9, is a normal type of butterfly valve - Handle Type WCB Valve Body PTFE. LWBV-9 F4 Wafer Type Butterfly Valve with WCB Valve Body

Fluorine-lined butterfly valve, rubber-lined butterfly valve, as a component used to realize the on-off and flow control of the pipeline system, has been extremely widely used in many fields such as petroleum, chemical industry, metallurgy, water and electricity. In the well-known butterfly valve technology, its sealing form mostly adopts a sealing structure, and the sealing material is rubber, polytetrafluoroethylene, etc. Due to the limitation of structural characteristics, it is not suitable for industries such as high temperature resistance, high pressure resistance, corrosion resistance, and wear resistance. An existing relatively advanced butterfly valve is a triple eccentric metal hard-sealed butterfly valve. The valve body and the valve seat are connected components, and the sealing surface layer of the valve seat is welded with temperature-resistant and corrosion-resistant alloy materials.

Tianjin LIWEI provide the wafer butterfly valve with the body made of wcb. WCB cast steel valve can be divided into cast carbon steel, cast low alloy steel and other special steel, so we can provide the valve with complex shape, difficult to forge or machine, and high requirements for strength and plasticity.

Disc & Seal WCB Body Wafer Type Butterfly Valve

1. WCB valve body and seat are adopted with split design for easy maintenance and replacement.

2. After maching of valve body, because of without lining rubber, to avoid the pressure deformation of the lining rubber. Which ensure the accuracy of body symmetry and reduce the torque of butterfly valve.

3. Valve stem and valve body are equipped with 4 oil proof bearing, which is benefical to stem support. The upper shaft hole is equipped with 2 o-ring and 1 special rectangular screw ring water seal, which make the axial seal more reliable.

4. The 2 ends of the valve plate shaft hole are designed with grooves,which can effectively prevent damage of valve seat caused by the excessive extrusion when valve shaft is loaded into valve to ensure the sealing of valve seat end face and the valve plate.

5. 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.
