Principle function of D941X flange electric butterfly valve:

The opening and closing part of the butterfly valve of the gate valve manufacturer is a disc-shaped butterfly plate, which rotates around its own axis in the valve body to achieve the purpose of opening and closing or adjustment. The advantages of butterfly valves are simple structure, small size, light weight, small installation size, and rapid switching.

Electric flange butterfly valve is one of the most commonly used valve varieties in industrial pipelines. The butterfly valve is small in size, less material, light in weight, larger in diameter, and more economical than other valves. The pneumatic actuator can be quickly opened and closed by rotating 90°, and the operation is simple. At the same time, the valve has good fluid control characteristics. When the butterfly valve is in the fully open position, the thickness of the butterfly plate is the resistance of the medium flowing through the valve body, so the pressure drop generated by the valve is very small. When the opening degree is between about 15° and 70°, it can For sensitive flow control, the butterfly valve has greater advantages for large-diameter flow adjustment. Not suitable for process media with particles and high temperature.

D941X flange electric butterfly valve performance characteristics:

    ①The water line design of the sealing valve seat and the plane design of the sealing surface of the valve plate completely avoid the jamming phenomenon of the pneumatic valve caused by the long time not opening;

    ②The upper and lower middle holes of the valve plate are designed with spherical friction surface, which has smaller torque and better sealing;

    ③The valve seat has no backrest design, the torque is lighter, and it is also convenient for users to replace the valve seat;

    ④A variety of standards are applicable to flange to clamp hole connection.
