Highlight: Worm Gear Flanged Butterfly Valve
Product introduction:
It is installed in the diameter direction of the pipeline. Inside the cylindrical channel of the butterfly valve body, the disc-shaped butterfly plate rotates around the axis at an angle between 0° and 90°. When rotated to 90°, the valve is in a fully open state. This valve is generally installed horizontally.
The handle butterfly valve features a simple structure, small size, and light weight, composed of only a few components. It can be quickly opened or closed with a 90° rotation for easy operation, while having excellent fluid control characteristics. When the butterfly valve is in the fully open position, the thickness of the butterfly plate is the only resistance for the medium flowing through the valve body. Therefore, the pressure drop generated by this valve is very small, resulting in good flow control characteristics.
