Name: Straight stroke electric actuator
Introduction:
GW series intelligent integrated electric actuators use advanced large-scale digital integrated chips, and have professional digital torque sensors and displacement sensors. The integrated structure design creates perfect functions, excellent performance, exquisite beauty, simple debugging and convenient operation. The straight stroke electric actuator consists of a multi turn electric actuator and a linear propulsion device. The rotating torque is converted into axial thrust or traction force and continuously adjusted. The straight stroke linear propulsion device adopts the ball screw structure and is equipped with a sealing device. The material of the whole propulsion device is stainless steel. The connection between the straight stroke electric actuator and the valve is realized through a screw. It is suitable for driving single seat valve, double seat valve, cage sleeve valve and other straight stroke regulating valves. It is widely used in power station, light industry, petroleum, metallurgy, chemical industry, oil pipeline, water treatment and other automation systems. This electric actuator has three control modes: continuous regulation, manual remote control and local manual operation, which can meet the requirements of frequent regulation control and intermittent control.
