The quarter-turn electric valve actuators are used to control 0-90° rotating valves and other similar products, such as butterfly valves, ball valves, dampers, plug valves, louver valves, etc. It works at the voltage DC 24V, AC 110V, AC 220V, or AC 380V. This small electric valve actuator can be widely used in petroleum, chemical industry, electric power, metallurgy, pharmacy, paper making, energy, water treatment, shipping, textile, food processing, building automation and other fields.
The on-off electric valve actuator, with 2000Nm output torque and 0-90° rotation angle, has great advantages of compact size, light weight, quick opening and closing, easy installation, small operating torque, convenient operation, no need for maintenance and safe use.

* For the control circuit diagram, please refer to Electric Valve Actuator Instruction Manual.
** Due to different manufacturers and different operating environment, even the same type of valves actually has different working torque. Therefore, it is recommended that when selecting a electric valve actuator, the operating torque of the valve should be 60% ~ 80% of the rated output torque of the actuator.

Tips: Control mode of electric valve actuator
1. On-off type (open loop control)
On-off type electric valve actuator generally control the valve either in the fully open position or in the fully closed position. Such valves do not require precise control of the medium flow.
The on-off electric valve actuator can be divided into the split type and the integrated type due to different structures. When selecting the electric valve actuator, it should figure out which type is more suitable, otherwise it will often cause the mismatch with the control system in the field installation.
2. Regulating type (closed loop control)
The regulated electric valve actuator not only has the function of the on-off type, but also can precisely control the valve to regulate the flow of the medium. The control type of the regulated electric valve actuator generally has a current signal (4 to 20mA, 0 to 10mA) or a voltage signal (0 to 5V, 1 to 5V).Besides, the regulated electric valve actuator has loss of signal protection. When the control signal is lost due to faults, the electric actuator will control the valve to open and close to the set protection value. The common protection values are full open, full off, and in-situ.
