Worm Gear Wafer Butterfly Valve

The butterfly disc of the worm gear butterfly valve is installed in the diameter direction of the pipeline. In the cylindrical channel of the butterfly valve body, the disc-shaped butterfly plate rotates around the axis, and the valve can be closed by rotating the worm gear head clockwise by 90°, and the valve can be opened by rotating the handle counterclockwise by 90°. This type of valve is usually installed horizontally in the pipeline.Worm Gear Wafer Butterfly Valves are not limited by caliber, minimum DN50, large to more than 1 meter caliber, can use worm wheel drive. It can also be used in medium and high pressure environment.

Overview

Features:

1. The handle of lever butterfly valve directly drives the valve plate, switching quickly, but laborious; Worm gear butterfly valve drives the valve plate through the worm gear, switching slowly, but labor-saving. Therefore, when the pressure in the pipe is large, the handle butterfly valve is especially laborious.

2. Butterfly valve commonly used in the project is generally worm gear butterfly valve, because in addition to labor-saving, its sealing is better than the handle butterfly valve, especially under the environment of high switching frequency, the service life is higher than the handle butterfly valve.

3. Handle butterfly valve is generally small diameter DN200 or less, because the general small diameter of the torque is smaller, you can directly open and close by hand, worm gear butterfly valve with a gear box to drive the valve stem rotation.
