The range includes the Series 82 aluminium actuator, Series 83 180-degree actuator and Series 84 stainless steel actuator, providing flexible options for different valve types, operating environments and torque requirements.
Pneumatic Valve Actuators for Industrial Applications
Valbia pneumatic actuators are mainly used to automate isolation and control valves in industrial processes. They are suitable for a wide range of sectors, including manufacturing, water treatment, food and beverage, chemical processing, pharmaceutical production, utilities and oil and gas.
With compact construction, high-quality materials and a proven actuator design, they provide a dependable solution for customers who need fast, repeatable valve movement using compressed air.
Key Benefits
ATEX Certified for Hazardous Areas
Certified to ATEX II 2GD T6 for use in gas (Zone 1) and dust (Zone 21) environments, supporting safe operation in explosive atmospheres.
The Series84 actuator offers the same compact design and technical features as the Series82, but with a stainless steel body, end caps and pinion. It is suited to more demanding, corrosive or hygienic environments.
Robust Rack and Pinion Design
The twin rack and pinion design provides constant torque output, balanced internal forces and a compact actuator body, helping to deliver reliable long-term performance.
Designed for Long Service Life
Features such as hard anodised aluminium bodies, low-friction piston guides, stainless steel fasteners and pre-lubricated internal components help reduce wear and support dependable operation.
Compatible with Industry Standards
Valbia pneumatic actuators are designed with ISO 5211-DIN 3337 valve mounting andNAMUR connections for solenoid valves and accessories, making integration straightforward.
Options for Specialist Environments
Special versions are available for high temperature, low temperature and corrosive environments, including nickel plated and PTFE coated options.
Pneumatic Actuator Series Available
Valbia Series 82 Pneumatic Actuators
Aluminium pneumatic actuators with 0°–90° rotation, available in double acting and spring return versions.
Valbia Series 83 Pneumatic Actuators

Q&A
What is a pneumatic actuator used for?
A pneumatic actuator uses compressed air to open, close or control a valve. It is commonly used for automating ball valves and butterfly valves in industrial process systems.
What is the difference between double acting and spring return pneumatic actuators?
A double acting actuator uses air pressure to move the actuator in both directions. A spring return actuator uses air pressure in one direction and springs to return the actuator to its fail-safe position.
Can pneumatic actuators be used in corrosive environments?
Yes. Valbia offers options including stainless steel actuators, nickel plated finishes and PTFE coated versions for more demanding or corrosive environments.
Are pneumatic actuators suitable for ball valves and butterfly valves?
Yes. Valbia pneumatic actuators are commonly used to automate quarter-turn valves, including ball valves and butterfly valves.
