Explosion-Proof Electric Actuated Ball Valves: Structure, Features & Technical Parameters

An explosion-proof Electric Actuated Ball Valve is a type of valve where the ball rotates 90° around an axis perpendicular to the passage. Composed of a rotary explosion-proof angular stroke electric actuator and an O-type valve structure, it belongs to the high-performance rotary type regulating or on-off valve category. It accepts the input and output of current signals or voltage signals from industrial automation control (DCS, PLC system) instruments, and can realize proportional regulation or two-position on-off control of fluid media in process pipelines, thereby achieving automatic control of parameters such as flow rate, pressure, temperature, and liquid level of the fluid media.

Structural Features

1. Low Fluid Resistance: It has the smallest fluid resistance among all valve types. Powered by AC220V, AC380V, or DC24V power supply voltage, it can be controlled to operate by accepting current signals or voltage signals (4-20mA, 0-10mA, or 1-5VDC). The torque output by the angular stroke rotates the ball 0-90° to complete the opening and closing action or regulating action.

2. Full Electronic Electric Actuator: Adopting an electromechanical integration mechanism, it has functions such as in-machine servo operation, opening signal position feedback, position indication, and manual operation. It has strong functions, reliable performance, and simple connection. By inputting current signals or voltage signals, the rotation angle of the ball core (0-90°) is changed to realize proportional regulation action.

3. Smooth Ball Core Channel: The channel of the ball core is flat and smooth, which is not easy to deposit media and can perform pipeline pigging. It has a simple structure, light weight, and good sealing performance. It is especially suitable for occasions requiring zero leakage.
