Electric Actuator
Electric actuator, also known as electric actuator. It is a driving device that can provide linear or rotary motion. It uses some kind of driving energy and works under some kind of control signal.
Linear-turn electric actuator is an electric actuator which outputs linear displacement and can be used to control various control valves in need of linear displacement, such as single and double-seat control valve, sleeve control valve, high temperature and high pressure water supply valve, desuperheater water and other control valve. Explosion-proof Grade : IP67.

Brief introduction of linear-turn device
The linear-turn device works with various types of multi-turn actuators to form linear-turn electrical actuator for various applications, such as ST6+VE50S, T14+VE200S, etc. For details, please refer to next pages. In selecting parameters for electrical actuators, please follow the formula below:
Actuator torque = operating thrust * moment/thrust Full-stroke cycles = Max. stroke * cycle/stroke Operating time = 60* cycles/actuator speed (rpm)
The linear-motion devices can work with brackets of various sizes, depending on the adapter size of regulating valve. Please consult our salesperson for details.
When the actuation mechanism is installed at the following positions, split control cabinet is especially helpful: At places difficult to access (man hole or overhead positions, etc.) On equipment with intensive vibration. On places with extremely high/low temperature. The maximum allowed distance from control cabinet to actuation mechanism is 50 meters.
Easy and Convenient Mechanical Operation
1. Easy limit adjustment 2. Self-locking at all speeds 3. Continuous gear transmission between motor and valve 4. Excellent vibration resistance on main mechanical components 5. No regular maintain required, gear lubrication is effective throughout its service life 6. High gear system efficiency and low wear 7. High performance and low noise Hand wheel does not rotate during electrical control; automatic manual and motor operation switching.
