What Is a Valve Actuator?
A valve actuator is a device used to automatically open, close, or regulate the position of a valve to control the flow of liquids, gases, or other media within a system. Unlike manual operation, valve actuators provide mechanical movement using an external power source such as electricity, pneumatic pressure, or hydraulic pressure.
Types of Valve Actuators – Linear vs Rotary Valve Actuators
Depending on the valve type, a valve actuator can produce linear motion, commonly used with gate, globe, and diaphragm valves, or rotary motion, which is ideal for ball, butterfly, and plug valves. Valve actuators enable precise, repeatable, and remote control of flow processes.
Applications of Valve Actuators
They are essential components in industrial automation, water treatment, HVAC systems, oil and gas facilities, and chemical plants, where reliability, safety, and operational efficiency are critical.
