In addition to electric drives, hard-seal butterfly valves are driven by electric motors, worm gear rods, and pneumatics. The butterfly plate of the multi-level hard-seal butterfly valve is installed in the diameter direction of the pipe. In the cylindrical passage of the butterfly valve body, the disc-shaped butterfly plate rotates around the axis, and the rotation angle is between 0° and 90°. When the rotation is 90°, the valve is fully opened.
The multi-layer hard-sealed flanged butterfly valve is an eccentric metal seal structure, the sealing form is a metal-to-metal seal, the metal seal can be replaced with a metal seal, the stainless steel plate and the graphite composite plate seal ring to the metal seal. The drive form of the hard seal butterfly valve is not only electricity In addition to hydraulic, electric, manual, worm gear transmission, pneumatic and so on.
