Electric ball valves are important actuators in industrial automation control systems. Electric butterfly valves belong to a variety of electric valves and electric control valves. The main connection methods of butterfly valves are: flange type and wafer type; The main sealing forms of butterfly valves include rubber sealing and metal sealing. The butterfly valve controls its opening and closing through a power signal. This product can be used as a shut-off valve, control valve, and check valve for pipeline systems. Equipped with a manual control device, in case of power failure, it can be temporarily operated manually without affecting usage. A ball valve is a valve that rotates around the axis of the valve stem based on the movement of the valve disc. The change in the valve seat opening is directly proportional to the valve disc stroke. It is mainly used to cut off or connect the medium in pipelines, and can also be used for fluid regulation and control. It is a pipeline pressure component for industrial automation process control.

Common faults of electric ball valves:

The typical malfunction of electric ball valves is the safety valve, the spring between the valve stem, and the behavior of one installed in the actuator, which pushes the valve back and forth in one of the positions of the gate. This may be the closed body, and the control fluid is applied to the piston to overcome the spring force in the actuator, thus maintaining it in other positions. Therefore, as a control condition, it is maintained for a long time when this structure of the valve is abandoned at a large depth, The pressure on the body is significantly lower than the pressure on the surrounding sea surface, and the ball valve spring must be large enough. The force to close the valve cannot be sufficient due to the pressure on the body to move the door to its failed position. May occur in the case of * end. This reduces the size of the actuator and increases the depth rating of the valve.

Troubleshooting method for electric ball valves:

Due to ball valve failures, including in this category, the valve body has a gate that intersects with a structure and a cavity. Traditional valves open and close between positions, and are responsible for moving the actuator between these positions. As it is also in the case of this type of valve, the actuator includes an engine hood installed in the valve body and connected to another valve stem.
