1. Product introduction
Brief introduction to the working principle of disc ball valve
The working principle of the disc ball valve is as follows: in the closed position, the ball is pressed against the seat by the mechanical pressure of the valve stem. When the handwheel is turned counterclockwise, the stem moves in the opposite direction, and its bottom angular plane releases the ball from the seat. The stem continues to lift and interacts with the search pin in the spiral groove of the stem so that the ball begins to rotate without friction.
The three-piece ball valve is small in size and consists of three parts of the valve shell, which is formed by clamping the middle valve body and the valve ball from both ends through four longer bolts. Its advantage is that the maintenance disassembly does not need to remove the pipe thread, directly remove the four bolts, the middle part of the valve body can be taken out. It is suitable for small volume and narrow space of light industrial machinery. It has the characteristics of small volume, simple matching and large circulation capacity, especially suitable for occasions where the medium is viscous, containing particles and fiber properties. Electric ball valve is widely used in food, environmental protection, light industry, petroleum, paper, chemical, teaching and research equipment, electric power and other industries of industrial automatic control system.

Note:
1, please be sure to connect the power supply phase sequence, so as to avoid damage to the valve or actuator.
2. Manual operation is prohibited when powered on.
3, outdoor use must give the electric actuator with a protective cover to prevent aging.
4. Tighten the screws after opening the cover to prevent water or dust from entering the electric actuator.
5, please do not install around explosive gas, if you need explosion-proof order, please explain.
6. Please confirm that the input voltage and distribution contact are correct.
7, prohibit overload use of electric actuators.
