Pneumatic Actuators

Pneumatic Actuator Supplier & Dealer in Mumbai, India — Authorized Elomatic, Avcon, Valmet Channel Partner Since 1966

CBT Flow Solutions Pvt. Ltd. is an authorized dealer, distributor, and supplier of pneumatic actuators in Mumbai and across India. Established in 1966, we are one of India’s most experienced pneumatic actuator suppliers — serving petrochemical plants, pharmaceutical factories, oil and gas facilities, water treatment plants, and process automation industries for over 60 years. We supply pneumatic actuators from two trusted brands — Elomatic (Finland) and Avcon — in rack & pinion and scotch yoke designs, single acting (spring return) and double acting configurations, torque range 5 Nm to 2000 Nm, suitable for ball valves, butterfly valves, and plug valves from DN15 to DN600.

What is a Pneumatic Actuator?

A pneumatic actuator is a mechanical device that converts compressed air energy into rotary or linear mechanical motion to operate an industrial valve. In industrial plants, pneumatic actuators are used to automate ball valves, butterfly valves, plug valves, and gate valves — enabling remote operation, automated process control, and fail-safe shutdown without manual intervention.

How Does a Pneumatic Actuator Work?

Compressed air (typically 3 to 8 bar) is supplied to one or both sides of a piston inside the actuator body. In a rack & pinion actuator, the air pressure drives two opposed pistons that move a rack gear, which rotates a central pinion shaft by 90° — opening or closing the valve. In a scotch yoke actuator, a slider-crank (yoke) mechanism converts the linear piston movement into rotary shaft motion.

WHY PNEUMATIC ACTUATORS ARE PREFERRED IN PROCESS INDUSTRIES:

• No electricity required at the valve — safe for hazardous area (Zone 1, Zone 2)
• Fast stroking speed — valve opens/closes in 1–3 seconds
• Inherently fail-safe — spring return models move to safe position on air loss
• Low maintenance — no electrical components at the valve
• Cost-effective — compressed air is available in most industrial plants
• Explosion-proof by design — no sparks, suitable for flammable environments
• Easy integration with solenoid valves, positioners, and SCADA systems

TYPES OF PNEUMATIC ACTUATORS — COMPLETE GUIDE

1. RACK & PINION PNEUMATIC ACTUATOR
The most common type for quarter-turn valve automation. Two opposed pistons drive a rack gear that rotates a central pinion shaft by 90°. Delivers uniform torque throughout the stroke. Compact, lightweight, cost-effective.
– Best for: Ball valves, butterfly valves, plug valves — DN15 to DN300
– Available: Double acting and single acting (spring return)
– Material: Aluminium body (standard), Stainless Steel body (for corrosive environments)
– Torque range: 5 Nm to 2000 Nm

2. SCOTCH YOKE PNEUMATIC ACTUATOR
Uses a slider-crank mechanism (yoke) that delivers higher torque at the beginning and end of the stroke — exactly where maximum valve breakaway torque is needed. Heavier duty construction for large valves.
– Best for: Large ball valves, gate valves — DN200 and above
– Available: Double acting and spring return
– Torque range: 200 Nm to over 10,000 Nm
– Preferred in: Oil & gas, petrochemical, pipeline isolation

3. SINGLE ACTING PNEUMATIC ACTUATOR (Spring Return)
Uses compressed air to stroke in one direction. An internal spring returns the actuator (and valve) to its original position when air supply is removed. FAIL-SAFE — valve automatically moves to safe position (open or closed) on air failure.
– Fail-open (spring opens the valve) or fail-closed (spring closes the valve)
– Mandatory for: Safety shutdown valves, emergency isolation, ESD systems
– Also called: Spring return actuator, fail-safe actuator

4. DOUBLE ACTING PNEUMATIC ACTUATOR
Uses compressed air for both opening and closing strokes. Higher torque output than equivalent single acting. No automatic failsafe — requires separate failsafe system (accumulator or interlock).
– Higher torque — suitable for large, high-pressure valves
– More precise positioning control
– Lower cost than equivalent spring return
– Used where: Failsafe not required, or separate failsafe system provided

5. DIAPHRAGM ACTUATOR (Linear)
Uses a flexible diaphragm and compressed air to produce linear (push-pull) motion. Used with linear control valves (globe valves, pinch valves, diaphragm valves) for throttling and flow control.
– Best for: Process control valves, modulating service
– Available with positioner for 4-20 mA control signal

6. STAINLESS STEEL PNEUMATIC ACTUATOR
Standard rack & pinion actuator with stainless steel body instead of aluminium — for offshore, marine, coastal, and highly corrosive environments.
– Best for: Offshore platforms, chemical plants, coastal installations
– Available in SS304 and SS316
