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.
ST+VE/SRA+VE series linear-turn electric actuator has achieved an excellent reputation over the years in this market thanks to a range of actuators providing the following features:
Compact construction with a high output torque
Self-locking gear train to maintain the position of the valve when the actuator is de-energized
Very good resistance to vibrations
Very simple settings - no specific tool required
Adjustable mechanical travel limit stops to prevent overtravel
Removable drive socket for easy machining
Emergency handwheel and mechanical position indicator provided on all actuators as a standard
3-phase power 380v, 50Hz
Single phase power 220v, 50Hz
ST(SRA)+VE Linear-turn Actuator
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.
Internal wiring
The asynchronous motor used on Bernard electrical actuator provides the highest nominal torque ratio on starting, which makes it competent in coping with all difficult situations and frequent starting operations.
1. Asynchronous motor provides high torque on starting
2. Motor overload protection
3. Motor overheat protection
Motor insulation grade F
