Worm Gear Butterfly Valve with WCB body: High Strength, High Wear Resistance, High Reliability
Butterfly valve is a pipeline valve that uses a disc-shaped disc to rotate and control the medium. It has the characteristics of simple structure, light weight, flexible operation and good sealing performance. Butterfly valves are widely used in water conservancy, electric power, petroleum, chemical industry, metallurgy and other industries, and can be used to adjust or cut off the flow of various corrosive and non-corrosive media.

The material of the butterfly valve body is an important factor affecting its performance and life. Different materials have different characteristics and scope of application. WCB valve body is a kind of carbon cast steel, which is the abbreviation of WCB and WCC cast steel in the American ASTM A216 standard. WCB valve body has the following advantages:
- High strength: The carbon content of WCB valve body is about 0.3%, which belongs to low carbon steel, but its strength is more than twice that of gray cast iron, and it can withstand greater pressure and temperature.
- High wear resistance: the hardness of WCB valve body is HB150-180, which is more than double that of gray cast iron, and has good wear resistance and impact resistance.
- High reliability: WCB valve body is manufactured by liquid forming process, which can produce valve body with complex shape and reasonable structure, avoiding defects and stress concentration that may occur during forging or cutting.
Worm gear butterfly valve is a butterfly valve operated by a worm gear transmission. It has the following advantages over the butterfly valve operated by the handle:
- Easy operation: The worm gear drive can amplify the operating torque and reduce the operating force, making the operation easier and smoother.
- Accurate adjustment: The worm gear transmission can realize small angle adjustment, making the flow control more precise and sensitive.
- Safe and reliable: The worm gear drive can realize self-locking function to avoid misoperation or leakage caused by external force or medium pressure.
To sum up, the worm gear butterfly valve with WCB valve body is a high-strength, high-wear-resistant, high-reliability pipeline valve, suitable for water, steam, air, hydrogen, ammonia, nitrogen and Petroleum products and other media.
