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.
