Product Description

Wafer butterfly valve This product is composed of a rubber seal butterfly valve, a carbon steel or stainless steel valve plate, and a valve stem. It is suitable for regulating flow and intercepting media in water supply, drainage and gas pipelines with temperatures ≤80~120ºC such as food, medicine, chemical industry, petroleum, electric power, light textile, papermaking, etc. Its main features are:
1. The design is novel and reasonable, the structure is unique, the weight is light, and it can open and close quickly.
2. The operating torque is small, the operation is convenient, labor-saving and dexterous.
3. It can be installed at any position and is easy to maintain.
4. The seals can be replaced, and the sealing performance is reliable and achieves two-way sealing and zero leakage.
5. The sealing material is resistant to aging, weak corrosion, and long service life.

A metal seated butterfly valve operates in a quarter turn style, meaning that  rotating the closed disc 90° will fully open the valve, and vice versa. They can also be opened incrementally in order to throttle flow.

A metal seated butterfly valve operates in a quarter turn style, meaning that rotating the closed disc 90° will fully open the valve, and vice versa. They can also be opened incrementally in order to throttle flow. This can be accomplished manually, but throttling flow is more precise when used in conjunction with an actuator. Actuators can be customized to allow incremental flow, by using positioners in the case of pneumatic and hydraulic actuators, or by using modulating boards in the case of electric actuators.









Applications of Metal Seat Butterfly Valves

Metal Seated Butterfly Valve is widely used in petroleum, natural gas, piped gas and medicine, food industry, industrial environmental water treatment and shipping industry.
