1. Introduction

Valve electric actuators are electromechanical devices designed to control the operation of valves. These actuators use electric motors to drive the valve stem, enabling precise control over the opening and closing of valves. They offer numerous advantages over traditional manual or pneumatic actuators, such as enhanced accuracy, remote control capabilities, and ease of integration with automation systems.

2. What Are Valve Electric Actuators?

Valve electric actuators are devices that convert electrical energy into mechanical motion to operate valves. They consist of an electric motor, a gearbox, and a drive mechanism that converts rotational motion into linear motion. These actuators are available in different types, including quarter-turn actuators and multi-turn actuators, to suit specific valve requirements.

3. Working Principle of Valve Electric Actuators

Valve electric actuators operate based on the principle of converting electrical energy into mechanical force. When an electric current flows through the motor windings, it generates a magnetic field that interacts with permanent magnets or electromagnets. This interaction causes the motor shaft to rotate, which, in turn, drives the valve stem to open or close the valve.
