Pneumatic Flange Butterfly Valve
Other Products
I. Introduction:
The D643H pneumatic flange butterfly valve offers various actuation forms including manual, worm gear, pneumatic, hydraulic, electric, and electro-hydraulic integrated actuators, enabling remote control and automated operation. The metal hard-sealed butterfly valve series is a long-life, energy-saving butterfly valve. Its structure is designed using the three-dimensional eccentric principle, and the valve seat adopts a multi-layer structure compatible with hard and soft sealing, featuring exquisite processing and advanced technology. This product is composed of main components such as the valve body, butterfly plate, multi-layer valve seat, valve stem, and transmission mechanism. Therefore, it is widely used in pipelines conveying corrosive media in industries such as metallurgy, electric power, petroleum, chemical industry, air, coal gas, flammable gas, and water supply and drainage.
II. Features:
1. Small opening torque, flexible and convenient, labor-saving and energy-saving.
2. Three-dimensional eccentric structure ensures the butterfly plate is tighter when closed, providing reliable sealing performance and achieving zero leakage.
3. Resistant to high pressure, corrosion, and wear, with a long service life.
