Industrial plants operating in hazardous environments require reliable automation equipment designed with the appropriate explosion-protection requirements in mind. An ATEX certified pneumatic actuator is used for automated valve operation where explosive atmospheres may be present due to flammable gases, vapours, mists or combustible dust.
Alis Valves supplies pneumatic actuator and valve automation solutions from Ahmedabad, Gujarat, India, for industrial applications across India and international markets. Our pneumatic actuator solutions can be configured for automated operation of quarter-turn valves such as ball valves and butterfly valves, with suitable accessories and control components.
For projects requiring ATEX compliance, customers should select an actuator configuration and certification that matches the hazardous-area classification and application requirements.
What Is an ATEX Certified Pneumatic Actuator?
An ATEX pneumatic actuator is a pneumatic valve actuator intended for applications where explosion-protection requirements apply.
Unlike conventional automation equipment, hazardous-area applications require careful consideration of potential ignition sources and the overall equipment configuration. ATEX requirements address equipment intended for potentially explosive atmospheres, including environments involving gases, vapours, mists and dusts.
A pneumatic actuator uses compressed air to generate rotary or linear mechanical movement. For quarter-turn valve automation, rotary pneumatic actuators are commonly used to open, close or modulate valves.

Alis Valves is based in Ahmedabad, Gujarat, an established industrial manufacturing and engineering centre. The company supplies pneumatic actuator-operated valves and automation accessories for industrial applications. Its existing product range includes pneumatic actuator-operated ball valves, butterfly valves and control valves.
For customers looking for an ATEX pneumatic actuator supplier in India, the correct actuator should be selected according to:
- Valve torque requirement

Pneumatic Actuator Product Range
1. Double Acting Pneumatic Actuator
A double acting pneumatic actuator uses compressed air for both opening and closing movement. It is suitable where controlled pneumatic operation is available in both directions.
Typical applications include:
- Ball valves
- Butterfly valves
- Process isolation valves
- Automated on/off valves
- Industrial valve packages
2. Single Acting Pneumatic Actuator
A single acting pneumatic actuator, also known as a spring return pneumatic actuator, uses compressed air for one direction and springs for the return stroke.
This configuration can be selected when a defined fail position is required, subject to the valve and process design.
3. Pneumatic Rotary Actuator
A pneumatic rotary actuator converts compressed-air energy into rotary motion and is commonly used for quarter-turn valve automation.
Typical applications include:
- Pneumatic ball valves
- Pneumatic butterfly valves
- Plug valves
- Damper applications
- On/off valve automation
4. Pneumatic Actuator Operated Valve
Alis Valves supplies actuator-operated valve solutions combining pneumatic actuators with industrial valves and suitable automation accessories. Existing Alis product information covers pneumatic actuator-operated ball valves, butterfly valves and control valves.
Why Use Pneumatic Actuators in Hazardous Areas?
Pneumatic actuation can be useful in hazardous industrial environments because the actuator itself is powered by compressed air rather than an electric motor.
However, the complete valve automation assembly still needs to be evaluated. Solenoid valves, limit switches, positioners, junction boxes and other electrical components may have their own hazardous-area requirements.
Therefore, an ATEX-rated actuator should not automatically be described as making the entire valve assembly explosion-proof.
For an ATEX project, the equipment selection should consider the complete installation and applicable certification requirements.
ATEX Pneumatic Actuator for Oil & Gas
Oil and gas facilities can contain areas where flammable gases and vapours create potentially explosive atmospheres. Automated valves in such plants may therefore require appropriately selected hazardous-area equipment.
ATEX pneumatic actuators can be considered for applications such as:
- Oil terminals
- Refineries
- Gas processing
- Petrochemical plants
- Storage facilities
- Pipeline systems
- Tank farms
- Loading and unloading systems
The appropriate equipment category, protection concept and certification should always be verified against the project’s hazardous-area classification.
Pneumatic Actuator for Chemical & Petrochemical Industries
Chemical processing plants often handle flammable or combustible materials. Automated flow control therefore requires careful equipment selection.
An ATEX certified pneumatic actuator for chemical industries can be used with suitable valve assemblies for:
- Chemical processing
- Petrochemical plants
- Solvent handling
- Storage systems
- Process isolation
- Automated flow control
The final configuration should be selected according to the process medium, valve torque, hazardous-area classification and required certification.

How to Select an ATEX Pneumatic Actuator
Before purchasing an ATEX pneumatic actuator, provide the following information to the supplier:
1. Valve Type
Ball valve, butterfly valve, plug valve or another quarter-turn valve.
2. Valve Torque
The actuator must provide sufficient torque for the valve throughout its operating cycle.
3. Operating Pressure
Specify the available instrument-air pressure.
4. Action
Choose between:
- Double acting
- Single acting / spring return
5. Fail Position
For spring-return applications, establish whether the valve needs to fail:
- Open
- Closed
6. Hazardous Area Classification
Provide the project’s required hazardous-area classification and applicable certification.
7. Temperature
Specify ambient and process-related temperature requirements.
8. Accessories
Identify required solenoid valves, limit switches, positioners and other automation components.
