Electric ball valve principle | Electric ball valve working principle
The electric ball valve is mainly composed of an electric actuator and a ball valve. The cock body is a ball with a 90-degree rotation. Electric ball valve is not only a good product for throttling, blocking, cutting, on-off, and diversion, it is also the first choice in the flow control system. It has many characteristics such as pressure resistance,

temperature resistance, corrosion resistance, low flow resistance, long service life, and wide application range. To
The working principle of the electric ball valve: The electric ball valve mainly relies on the adjustment of the electric current in the electric actuator to operate the ball valve. The input and output signal of the electric actuator is 4-20mA and the standard signal of the 220VAC power supply. The motor group drives the gear and worm torque to control the opening and closing of the ball valve, to distribute and change the flow direction of the medium or to adjust the proportional degree of the spool rotation, namely The opening of the valve is proportional to the control fluid, or percentage.
Electric ball valve application:

The electric ball valve does not need to be operated manually, but is operated intelligently. In the production process, the environmental site determines all the factors. Electric ball valves used in high pressure, high temperature or low pressure and low temperature environments are different. The following points should be noted:
1. For low temperature and low pressure, the material does not need to be adjusted too much.
2. In the case of high pressure and high temperature, high temperature and high pressure resistant materials should be used as the electric ball valve material, such as stainless steel and alloy, which can withstand high pressure and high temperature.
3. The internal parts of the electric ball valve need to be replaced to reduce the damage to the valve core, and it is also conducive to the flow of the medium and avoid the coking and blockage of the electric ball valve.
4. When the electric ball valve is opened, some machinery to avoid vibration can be installed to prevent the internal structure of the electric ball valve spool from being damaged when it is opened.
