EOM2-9 series integration type quarter turn electric actuator
The EOM series electric actuator is a motor-driven device that uses a combination of multistage reduction gear, worm gear, and other mechanisms to rotate and switch the valve device in a 90° rotation form through the output shaft. This actuator is primarily used to drive and control the Angle travel valve opening for various valve-like applications, such as butterfly valves, ball valves, and plug valves. The EOM intelligent type offers a torque range of 100-20000N.m, while the conventional EOM series electric actuator operates without a clutch, ensuring durability and stability of the stroke. These features enhance the transfer efficiency and reliability of the actuator.
- Features:
- Warranty: 2 years
- User Interaction Interface: Intelligent type is equipped with brand new UI control interface , with the specialized remote control, achieves a variety of function of the actuator configuration operation.
- Energy Efficiency: Single-phase and DC power supply is optional, ultra-low energy consumption,suitable for solar and wind powered applications.
- Patent Mechanic Design: EOM series of electric actuators are equipped with manual/ electric automatic switching function. No clutch design thus enables the handwheel to be rotated while the machine is running; this is to ensure the safety of the operator. Such design will be the mainstream trend in the future.
- 360° Position Indicator: Adopts high strength, anti- sunlight and RoHS-compliant plastic 3D window indicator. Users are able to observe the stroke position of the actuator within the 360° visual angle as there 's no dead angles.
- Interchangeable Connecting Flange: The base connecting holes are in accordance with ISO5211 standard, also with various connecting flange sizes. It can be replaced and rotated for the same type of actuators in order to achieve with different hole positions and angles of the valve flange connection purposes.
- Planetary Gears: Using high strength alloy steel for the planetary gear set. more compact and efficient, achieving greater output for the same volume. At the same time ,having differential input for motor drive and hand wheel operation, we are therefore able to operate electrically and manually at the same time.
- Sprocket Operation: Based on the features of operationg manually and electrically without clutch mechanism, sprocket operation is more convenient to operate the valve at higher positions.
