The disc of the butterfly valve is a disc that rotates on an axis at the position of the valve seat. The size of the angle of rotation determines the size of the valve opening and closing. The following will introduce how to choose an electric butterfly valve.
01 Valve stem diameter
If it is a multi-turn rising stem valve, then the electric valve cannot be installed on it, so when purchasing, you must pay special attention to the valve stem diameter to ensure that it can pass the maximum valve stem diameter. There are also requirements for the inner diameter of the hollow output shaft, which must be larger than the outer diameter of the valve stem of the rising stem valve.
02 Electric device output torque
Also pay special attention to the output torque of the electric device of the electric butterfly valve, which must be 1.2-1.5 times the maximum torque of the valve operation. If you want to choose a suitable electric butterfly valve, you can find a professional and regular butterfly valve manufacturer when making a choice to ensure quality.
03 Operating torque
When purchasing an electric butterfly valve, you need to consider not only the valve stem diameter, but also the operating torque. This is the most critical parameter in the selection of valve electric devices.
The most important thing about the electric butterfly valve when it is working is to control it through the size of stroke, torque or axial thrust. Because the use effect of the valve electric device is mainly determined by the type of valve and whether the device works in a standardized manner, it is a very critical and important equipment.
Therefore, if you find the right regular butterfly valve manufacturer and choose the right valve electric device, you can prevent overload to a large extent.
