Wafer Butterfly Valve -LWBV-12 ,is KITZ Aluminum Alloy Handle Aluminum Alloy Body Stainless Steel 

CF8 Wafer Butterfly Valve.


1. *Light aluminum alloy valve body, small torque, easy to use and install;

2. Aluminum die-cast valve body to prevent corrosion;

3. *Some multi-level progressive contact valve seat design allows the valve plate 

to gradually contact the valve seat during the closing process, which reduces 

unnecessary torque while ensuring good sealing performance, thereby prolonging 

the service life of the valve seat.

4. Some valve stem sealing rings prevent fluid leakage;

5. Valve seats of different materials adapt to different working conditions and have

 good anti-corrosion and sealing performance

6. The trajectory of the spherical valve plate makes the valve rotate flexibly and 

freely. The valve plate is processed as a complete spherical shape. Each part of 

the sealing surface is a part of the spherical surface, even the axial sealing 

surface at the upper and lower parts of the valve plate. This is no exception. 

When the sealing surface is in contact, it is quite smooth despite the contact. 

Therefore, the torque is reduced and the sealing performance is improved, especially 

the friction at the axial seal is reduced. The seat life of the technology has been 



The valve body is made of light aluminum alloy body, with low torque, preventing rust, and preventing long-term 

circulation of chilled water in the air conditioner. The low temperature of the fluid in the pipeline follows the conduction 

of the butterfly valve metal material and exchanges with the ambient air temperature to produce condensation. Products 

are widely used in industries such as fire-fighting pipelines, drainage, sewage, food, heating, gas, ships, hydropower, 

metallurgy, energy systems, and textiles.


The unique multi-level progressive contact seat design of the anti-condensation butterfly valve makes the valve plate 

gradually contact the seat during the closing process. *Some stem sealing rings prevent fluid leakage, while ensuring 

good sealing performance, reducing unnecessary The high torque, coupled with the stainless steel butterfly plate and 

internal parts, thereby prolonging the service life of the valve seat, and has a strong rust and corrosion resistance function.
