Electric soft seal pair butterfly valve

The electric flange butterfly valve is usually composed of a quarter-turn electric actuator (0~90° partial rotation) and a butterfly valve as a whole, and is assembled after commissioning. The structure is simple, small in size and light in weight, and consists of only a few parts. Moreover, it can be quickly opened and closed by rotating 90°, and the operation is simple, and the valve has good fluid control characteristics.

The electric flange butterfly valve is usually composed of a quarter-turn electric actuator (0~90° partial rotation) and a butterfly valve as a whole, and is assembled after commissioning. The structure is simple, small in size and light in weight, and consists of only a few parts. Moreover, it can be quickly opened and closed by rotating 90°, and the operation is simple, and the valve has good fluid control characteristics.

 

The disc of the electric flange butterfly valve is installed in the diameter direction of the pipe. In the cylindrical passage of the butterfly valve body, the disc-shaped disc rotates around the axis, and the rotation angle is between 0° and 90°. When the rotation is 90°, the valve is fully open.

 

The electric flange butterfly valve is simple in structure, small in size and light in weight, and consists of only a few parts. Moreover, it can be quickly opened and closed by rotating 90°, and the operation is simple, and the valve has good fluid control characteristics. When the flange butterfly valve is in the fully open position, the thickness of the disc is the only resistance when the medium flows through the valve body, so the pressure drop generated by the valve is small, so it has better flow control characteristics. The butterfly valve has two sealing types: a spring seal and a metal seal. Elastomeric sealing valve, the sealing ring can be mounted on the valve body or attached to the periphery of the disc.

 

Valves with metal seals generally have a longer life than elastomeric seals, but are difficult to seal completely. Metal seals can accommodate higher operating temperatures, while elastomeric seals have temperature-limited defects.
