Functions of Electrically Operated Ball Valve at Different Temperatures

Functions of Electrically Operated Ball Valve at Different Temperatures

1. The function of motor operated ball valve at different temperatures


Under medium, high temperature and high pressure, it is best to use metal materials to seal the motor operated ball valve. For areas where the valve is highly reliable with a long life and is not suitable for replacement for a long time, metal materials should also be used to seal the motor operated ball valve.


For valves used for normal temperature water, if the requirements are not high and it is inconvenient to disassemble and assemble for a long time, a motor operated ball valve with a soft seal structure should be used. If the quality of the vulcanized rubber can be ensured, the vulcanized rubber high-pressure gate valve ball valve should still be the main body of the large-caliber ball valve.


2. Installation of motor operated ball valve


The ball plate of the motor operated ball valve is installed on the diameter of the pipe. In the cylindrical safety passage of the oil circuit board of the motor operated ball valve, the disc-shaped ball plate rotates around the center line, and the rotation angle is between 0°-90°. When rotated to 90°, the valve is fully opened.


The motor operated ball valve has a simple and clear structure, small size, light weight, and consists of only a few parts. In addition, the valve can be opened and closed quickly by rotating 90°, and the actual operation is simple and clear. In addition, the valve also has excellent hydrodynamic control characteristics. When the motor operated ball valve is in the fully open position, when the material flows through the oil circuit plate, the thickness of the ball plate is the only frictional resistance.


Therefore, the air pressure caused by the valve is not large, so it has good flow monitoring characteristics. Motor operated ball valve has two sealing forms: elastic sealing and metal material sealing. For malleable sealing valves, the sealing ring can be embedded on the oil circuit board or installed near the ball plate
