ShareD941w-16c/16p Electric Ventilation Butterfly Valve
FEATURES
1. It features a simple structure, large diameter, light weight and convenient operation.
2. It features a small driving torque, flexible opening and closing, and convenient operation.
3. It can be installed at multiple stations and is not affected by the medium.
4. An oil seal retaining ring is set on the valve body. There is no visible gap between the sealing pairs, resulting in a low leakage rate.
5. The expansion gap between the butterfly plate and the valve body is large, which can effectively prevent jamming caused by thermal expansion and contraction.
