Eaton’s four-position valve actuator provides a full 360 degrees of rotary motion, with actuator position commanded by four power input pins in the electrical connector. A control logic board determines the shortest rotational distance from its current position and features over-voltage protection and position hold with loss of power and resume when power returns. Additional features can be added. Travel limits are controlled by four micro switches or hall effect sensors. The actuator provides visual and electrical indication and can be assembled with other Eaton valves using an adapter.
