Pneumatic butterfly valve with stainless steel valve plate and soft sealing gasket, flange connection

Short Description:

The D641X-16Q double-acting pneumatic soft-seal butterfly valve is composed of a pneumatic actuator and a butterfly valve. A pneumatic butterfly valve is a type of pneumatic valve that uses a circular butterfly plate rotating with the valve stem as the opening/closing component to achieve opening and closing actions. It is mainly used as a shut-off valve, and can also be designed to have regulation functions or both shut-off and regulation functions.

Product introduction

Pneumatic flange butterfly valve has small opening torque,flexible and convenient,labor-saving and energy-saving.It is composed of rubber sealed butterfly valve,carbon steel or stainless steel valve plate and stem.It is suitable for regulating flow and intercepting medium in water supply and drainage and gas pipelines with temperature<80~120℃,such as food, medicine, chemical industry, petroleum, electric power, light textile, paper making, etc. Using three dimensional eccentric principle design, the space movement track of the sealing surface is idealized, and there is no friction, interference between the sealing surfaces. In addition, the sealing material is properly selected, so that the sealing performance, corrosion resistance, high temperature resistance and wear resistance of the butterfly valve are reliably guaranteed.
