Electric clamp soft seal butterfly valve D971X

The main advantages of electric clamp soft seal butterfly valves are simple structure, small size, light weight, and low cost. Pneumatic hard seal butterfly valves have this feature, especially when installed in high-altitude tunnels. They are easy to operate through a two position five way solenoid valve control and can also adjust the flow medium. The fluid resistance is small, and the effective flow area of the pneumatic disc valve with a medium to large diameter is large when fully opened. The opening and closing are quick and labor-saving, and the disc can be opened and closed by rotating the disc lever 90 degrees. Due to the nearly equal force of the disc lever on both sides of the shaft, the torque direction is opposite, resulting in a small opening and closing torque. Good sealing can be achieved under low pressure. The sealing materials of the disc valve include nitrile rubber, fluororubber, edible rubber, and PTFE lining, which have good sealing performance. The hard sealed disc valve is a soft hard laminated metal plate with the advantages of metal hard sealing and elastic sealing, and has excellent sealing performance at low temperatures. The butterfly plate of the electric soft seal butterfly valve is installed in the diameter direction of the pipeline. In the cylindrical passage of the butterfly valve body, the disc-shaped butterfly plate rotates around the axis at an angle between 0 ° and 90 °. When it rotates to 90 °, the valve is fully open. The electric soft seal butterfly valve has a simple structure, small volume, and light weight, and is composed of only a few parts. And it only needs to rotate 90 ° to quickly open and close, with simple operation. At the same time, this electric valve has good 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 to flow through the valve body. Therefore, the pressure drop generated by this valve is very small, and it has good flow control characteristics. Butterfly valves have two sealing types: elastic sealing and metal sealing. Elastic sealing valve, the sealing ring can be embedded on the valve body or attached around the butterfly plate.

Valves with metal seals generally have a longer lifespan than those with elastic seals, but it is difficult to achieve complete sealing. Metal seals can adapt to higher operating temperatures, while elastic seals have the drawback of being limited by temperature.

1. This valve adopts a double eccentric structure, which has a sealing function that becomes tighter as it is closed, and the sealing performance is reliable.

2. The sealing auxiliary material is paired with stainless steel and nitrile oil resistant rubber, which has a long service life.

3. The rubber sealing ring can be located on the valve body or on the butterfly plate, and can be suitable for different characteristics of media for users to choose from.

4. The butterfly plate adopts a frame structure, with high strength, large overcurrent area, and low flow resistance.

5. The overall baking paint can effectively prevent rust and can be used in different media as long as the sealing material of the valve seat is replaced.

6. This valve has a bidirectional sealing function and is not controlled by the flow direction of the medium or the spatial position during installation. It can be installed in any direction.

7. This valve has a unique structure, flexible operation, labor-saving, and convenience.
