CHARACTERISTICS:
1. Explosion proof electric ball valves have low fluid resistance and are the ones with the smallest fluid resistance among all valve types. They are powered by AC220V, AC380V, or DC24V power supply voltage and can receive (4-20mA, 0-10mA, or 1-5VDC) current or voltage signals to control operation. By rotating the ball body by 0-90 ° with the torque output of angular stroke, the opening and closing action or adjustment action can be completed.
2. The fully electronic electric actuator adopts an electromechanical integrated structure, with functions such as internal servo operation, opening signal position feedback, position indication, manual operation, etc. It has strong functionality, reliable performance, and simple wiring. By inputting current or voltage signals, the rotation angle of the ball core can be changed (any angle from 0-90 °) to achieve proportional adjustment action.
3. The core channel is flat and smooth, not easy to deposit media, and can be used for pipeline ball passing. Simple structure, light weight, and good sealing performance. Especially suitable for situations that require zero leakage rate.
