首页 >> Products list >> Actuator

Classification：　Actuator

Product Name：　Quick Switch Electric Actuator

Product Description：

With whole stroke 0-90° to realize fully open &open single action in 3S or 4S, EA series quick switch electric actuator is satisfied with quick switch requirement of ball valve, butterfly valve, and other segmental electric quick switch valve.
This actuator is suited to high pressure, large pressure drops, and the quick switch services that solenoid valve is not available, which is matched with ball valve, V type control valve, butterfly valve, ventilation valve, damper, fan, dynamic balancing valve, plug valve, gyrating valve, and mechanical positioning rotation system in other industrial area.

The Characteristics of the products

    ★Quick switch
    This actuator has whole stroke 0-90° to realize fully open &open single action in 3S or 4S,
    ★Long service life
    More than 50,000 operation life without fault, keep your system operating safely and reliably.
    ★Miniature design
    This actuator is equipped with various segmental valve(ball valve, butterfly valve, plug valve.) to form industrial automatic control electric valve such as electric control valve, electric ball valve, electric butterfly valve and so on.
    With small volume, light weight, this actuator is easy to install in any direction of pipeline, and meets the requirements of complex pipeline and situation.
    ★Good seal performance.
    Seal standard: This actuator wholly immerses in water with no air leakage, and is best suitable for outdoor conditions.
    ★Good reliability
    The electrical components and precision parts are made of imported material to effectively ensure high quality and reliability of the product.
    ★Good pressure resistance performance
    EA series actuator has passed through 1500V high-pressure resistance test without electric leakage to ensure your system operating safely.
    ★The new technology for debugging and control device in electric actuators.
    Easy to use! Design by GRAT in China.
    It completely solved the problem of complex debugging and make the technology simpler.
    The debugging can be simplified from 5 steps to 1 step.
    The debugging for electrical and mechanical position can be easy achieved through rotating the knob on the top of the dial after electric actuators and valves are assembled together.
