DN50-200 D71X-16Q wafer butterfly valve(handle)
The opening and closing piece (butterfly disc) is driven by the valve stem and rotates around the axis of the valve stem.
Characteristics of butterfly valve
A small size, light weight;
B simple structure, quick opening and closing;
C sealing and regulating performance is good, and can achieve graded flow control;
D low flow resistance and operating torque;
E as a result of the movement of the disc with wiping sex, so most butterfly valve can be used with suspended solids media.
