China Wholesale Rubber Lined Butterfly Valve Factory - FD01-BV1DF-3G(Double flanged Butterfly Valve–Gear box Operation) – Fortis
China Wholesale Rubber Lined Butterfly Valve Factory - FD01-BV1DF-3G(Double flanged Butterfly Valve–Gear box Operation) – Fortis Detail:
●Brief
The butterfly plate of butterfly valve is installed in the diameter direction of pipeline. In the cylindrical channel of butterfly valve body, the disc-shaped butterfly plate rotates around the axis, and the rotation angle is between 0 ° and 90 ° and when the rotation reaches 90 ° the valve plate is fully open.
●Features
1. The connection between the butterfly plate and the valve stem adopts the structure without pin, which overcomes the possible internal leakage point.
2. The outer circle of butterfly plate adopts spherical shape, which improves the sealing performance and prolongs the service life of the valve, and keeps zero leakage after more than 50000 times of opening and closing under pressure.
3. The sealing element can be replaced, and the sealing is reliable to achieve bidirectional sealing.
