Pneumatic Actuators

Pneumatic actuators convert compressed air energy into mechanical motion to open, close or position valves automatically.

Function: Automate systems, reducing manual operation, for emergency shutdown and automatic adjustment.
Advantages: Durable, reliable, clean technology with swift movement and strong force.

What Is a Pneumatic Actuator?

Pneumatic actuators convert compressed gas or air energy into mechanical motion to control final components such as valves and dampers. They automate systems, reducing the need for human intervention, and are valuable for emergency shutdowns and automatic adjustment.

Tell us the valve type, size and torque, or the actuator part number you use today, and we will supply the matching actuator or an approved equivalent, with accessories.

Types of Pneumatic Actuators We Supply

Actuators and accessories to automate quarter-turn and linear valves.

Double-acting rack & pinion

Air drives the pistons in both directions for 90° rotation. Compact, efficient and the most common quarter-turn actuator.

90° rotationCompact

Spring-return actuators

Springs return the valve to a safe open or closed position if air or power fails. Used for fail-safe duties.

Fail closeFail open

Scotch yoke actuators

High breakaway torque for large ball, butterfly and plug valves in oil & gas and water.

High torque

Linear actuators

Straight-line motion for gate, globe and knife-gate valves and dampers.

Linear stroke

Solenoid valves & limit switches

NAMUR solenoid valves to switch the actuator and limit switch boxes to signal valve position. See our pneumatic valves.

NAMURPosition feedback

Positioners & manual overrides

Positioners for modulating control, plus manual override gearboxes for operation without air.

How to Choose the Right Pneumatic Actuator

Six details that decide which pneumatic actuator is right. Share them with us and we will match it for you.

Valve torque

Size the actuator from the valve's breakaway torque at your air pressure, with a safety margin.

Action

Double-acting for normal duty; spring return when the valve must go to a safe position on air failure.

Air supply

Use the minimum available air pressure for sizing, not the nominal pressure.

Mounting

Match the ISO 5211 flange and stem drive to the valve, or use a mounting kit.

Control

Choose on/off with a solenoid valve, or modulating with a positioner, plus position feedback.

Environment

For outdoor, offshore or hazardous areas, choose suitable coatings, stainless steel and certified accessories.

Where can I buy pneumatic actuators in Qatar?

Power & Control Trading W.L.L. supplies pneumatic actuators in Doha, Qatar, with delivery across the country. Call or WhatsApp +974 7133 7700 or email sales@pctqatar.com for a quote.

What is the difference between double-acting and spring-return actuators?

A double-acting actuator uses air to both open and close the valve. A spring-return actuator uses air to move one way and springs to move back, so the valve goes to a safe position if the air supply fails.

How do I size a pneumatic actuator?

Find the valve's breakaway torque, add the safety margin recommended by the valve maker, and pick an actuator whose output torque at your minimum air pressure exceeds it. For spring-return actuators, check the spring-end torque too.

What are ISO 5211 and NAMUR?

ISO 5211 is the standard flange and drive between a valve and its actuator. NAMUR (VDI/VDE 3845) is the standard interface for mounting solenoid valves and limit switch boxes onto the actuator.

What information do I need for a quotation?

Tell us the valve type and size, required torque, action (double-acting or spring return), air pressure, mounting flange and any accessories, plus quantity. The part number is enough if you have it.
