here are many types of electric actuators, which are called valve electric actuators in the industrial pipeline valve industry, and remote control intelligent electric actuators in the instrument industry, but there is no clear distinction in the industry now.
Angular stroke, linear stroke and multi-turn electric actuators are classified according to the movement mode. Actuator is a driving device that can provide linear or rotary motion. It uses a certain driving energy and works under a certain control signal. No matter which category has its own characteristics.
Angular stroke and linear stroke electric actuators are mostly modified on the basis of multi-turn: based on multi-turn electric actuators, equipped with worm gear two-stage reduction box to form 0-90° angular stroke electric actuators , Used to control angular stroke valves such as ball valves, cock valves, butterfly valves and louver valves; equipped with screw components to form a linear electric actuator, which outputs force and produces displacement. It is mainly used for gate valves and slide valves.
Multi-turn electric actuator: It needs to operate more than 360° to realize the opening and closing of the valve. It is mainly used for globe valves, pinch valves and diaphragm valves; it is often used to form electric valves or electric regulating valves with various valves (for example: gate valves, regulating valves). Valves, single-seat valves and other linear movement valves); use AC alternating current or DC direct current as the driving energy; according to the action mode, it is divided into two categories (electric switch type and electric adjustment type).
