Imported electric flange butterfly valve

The German Lake brand imported electric flange butterfly valve is an automatic control butterfly valve composed of an electric actuator and a flange butterfly valve body. According to different working methods and working conditions, it can be divided into switch control type (two-position switch control) and intelligent adjustment type (~analog signal control). Through the operation of the electric actuator, the rotating valve stem drives the disc to open within a range. and closed for use. The structural performance of the electric flange butterfly valve is better than that of the wafer butterfly valve. Generally, it is recommended to use the electric flange butterfly valve for working conditions with higher pressure and larger caliber.
Performance characteristics of imported electric flange butterfly valve
, an automatic butterfly valve that can be remotely controlled, and also has the characteristics of flange butterfly valve, and can be equipped with a wide range of butterfly valve diameters
, the power supply is driven by the electric butterfly valve It has a wide range of energy and power sources, a wide range of applications, saves human resources, and is more efficient
. It is easy to operate and can easily meet various control requirements. It can be realized by selecting different electric actuators. Signal feedback, flow adjustment, It has explosion-proof functions
, can achieve ultra-miniaturization, can achieve mechanical self-locking, and can replace different sealing rings to meet different working conditions.

Working principle of the imported electric flange butterfly valve
The imported electric flange butterfly valve uses the electric actuator to input a milliamp standard signal, and the motor set drives the gear turbine worm angular torque to drive the disc to rotate. When the valve is in the fully open position, the thickness of the butterfly plate is the only resistance when the medium flows through the valve body. Therefore, the pressure drop generated by the valve is very small, so it has good flow control characteristics. Electric flange butterfly valve has two sealing types: elastic seal and metal seal. For elastic sealing valves, the sealing ring can be embedded in the valve body or attached to the periphery of the butterfly plate. Valves with metal seals generally have a longer service life than valves with elastic seals, but it is difficult to achieve complete sealing. Metal seals can adapt to higher operating temperatures, while elastic seals have the disadvantage of being limited by temperature. If the electric flange butterfly valve is required to be used as flow control, the main thing is to correctly select the size and type of the valve.
