Description
Features
Compact structure: The Modbus RS485 RTU Electric Actuator Ball Valve has a compact structure design and small size. It can be installed in a small space, which is convenient for use and maintenance.
Reliable sealing: The opening and closing parts (ball) of the electric ball valve fit tightly with the valve seat, have good sealing performance, and can effectively prevent medium leakage.
Easy operation: The switching action of the electric ball valve can be realized by the electric actuator, which is easy to operate and can be controlled by remote control or automatic control system.
Small fluid resistance: The spherical shape of the electric ball valve makes the fluid have less resistance when passing through the valve, which can reduce fluid resistance loss.
Wide range of applications: Electric ball valves are suitable for various pipeline systems, such as chemical, petroleum, pharmaceutical, food, etc., and can be used for the transportation and discharge of gas, liquid and powder.
Easy maintenance: The repair and maintenance of the electric ball valve is relatively simple, and it can be maintained by simply disassembling and replacing parts, with a long service life.
structure
The electric ball valve is mainly composed of two parts: the electric actuator and the ball valve. The electric actuator is responsible for receiving the control signal and driving the motor to rotate, while the ball valve part includes components such as the valve body, ball, valve seat and valve stem. The valve body is the outer shell of the ball valve, and there is a channel inside for fluid flow; the ball is the opening and closing part of the valve, which can be connected, cut off or regulated by rotating 90 degrees; the valve seat serves as a sealing gasket for the ball to ensure that the fluid will not leak in the closed state.
The working principle of the electric ball valve is to receive the control signal through the electric actuator, drive the motor to rotate, and then rotate the ball around the valve stem axis through the transmission mechanism (such as gear worm gear). When the ball rotates to align with the channel, the fluid can pass smoothly; when the ball rotates to be perpendicular to the channel, the fluid flow is blocked, thereby achieving precise control of the fluid medium.
There are many types of electric ball valves. According to different connection methods, they can be divided into electric flange ball valves, electric wafer ball valves, electric welding ball valves and electric threaded ball valves, etc.; according to different sealing forms, they can be divided into soft-sealed electric ball valves and metal-sealed electric ball valves. In addition, there are many types such as floating ball valves, trunnion ball valves, V-port ball valves, and three-way ball valves.
Electric ball valves play an important role in industrial automation control systems. They have the characteristics of automatic control, fast switching, good sealing, strong fluid control ability and long service life. It is widely used in industrial automation control systems, HVAC systems, water supply and drainage systems, food and beverage processing, as well as medicine and life sciences.
