Electric Actuated 3-Piece Ball Valves

Electric Actuated 3-Piece Ball Valves can be controlled and operated with an input control signal (4-20mA DC or 1-5V DC) and a single-phase power supply. Featuring powerful functions, compact size, light weight, easy operation, reliable performance, simple matching and large flow capacity, they are especially suitable for occasions where the medium is viscous, particle-containing or fibrous. At present, these valves are widely used in industrial automatic control systems of various industries including food, environmental protection, light industry, petroleum, papermaking, chemical industry, teaching and scientific research equipment, and electric power.

Structural Features

1. Electric Actuated 3-Piece Ball Valves have low fluid resistance, among the lowest of all valve types. Powered by AC220V, AC380V or DC24V voltage, they can be controlled and operated upon receiving current or voltage signals (4-20mA, 0-10mA or 1-5V DC). The torque output in angular stroke rotates the ball 0~90° to complete on-off or regulating actions.

2. The all-electronic electric actuator adopts an integrated mechatronic structure, with built-in servo operation, position feedback of opening signal, position indication and manual operation functions. It boasts powerful functions, reliable performance and simple wiring. By inputting current or voltage signals, it changes the rotation angle of the spherical core (any angle from 0-90°) to achieve proportional regulation.

3. The spherical core channel is smooth and flat, preventing medium deposition and enabling pipeline pigging. With a simple structure, light weight and excellent sealing performance, it is particularly suitable for occasions requiring zero leakage rate.
