Understanding Actuated Valves: Control, On/Off, and Motor-Operated Valves

Actuated valves are essential components in industrial automation, allowing precise control of fluid flow. Let’s explore three key types: control valves, on/off valves, and motor-operated valves (MOVs).

1. Control Valves

Control valves regulate flow, pressure, or temperature within a system by adjusting their position based on signals from a controller. They are commonly paired with pneumatic or electric actuators for precise throttling.

Applications: Process industries like oil & gas, chemical plants, and power generation where accuracy is critical.

Key Advantage: Precise modulation of flow parameters.

2. On/Off Valves

On/off valves are designed for binary operation—either fully open or fully closed. They use actuators (pneumatic, electric, or hydraulic) to provide quick and reliable shutoff.

Applications: Safety-critical systems, emergency shutoffs, and fluid isolation in pipelines.

Key Advantage: Fast and fail-safe operation for critical tasks.

3. Motor-Operated Valves (MOVs)

MOVs use electric motors to automate valve positioning, allowing remote or precise operation. These valves are ideal for systems where manual operation is impractical.

Applications: Large pipeline systems in water treatment, power plants, and oil refineries.

Key Advantage: Reliable automation and precise positioning with minimal human intervention.
