Precision and performance where it counts

Actuators turn control signals into motion — opening, closing, or adjusting valves with accuracy and speed. They’re the driving force behind today’s most advanced control systems.

Here’s how actuators make a difference:

  • Precise control — Actuators adjust valve travel in real time, helping you regulate flow pressure, temperature, and other process variables with pinpoint accuracy.
  • Fail-safe operation — Many actuators feature spring return designs that move the valve to a safe position if power or air fails, an essential fail-safe feature in critical applications.
  • Automated efficiency — Paired with control valves, actuators automate manual tasks and reduce the risk of error, improving both safety and output.
  • Built to last — Our actuators are tough. With corrosion-resistant materials and IP-rated designs, they’re ready for even the harshest industrial applications.
  • Versatile options — We offer electric, pneumatic, and mechanical actuation options for quarter-turn valves, giving you the flexibility to match your system's needs.

At Process Systems, we offer a complete range of 90-degree turn actuation options for valve automation, including double-acting and spring-return pneumatic actuators, electric actuators in all common voltages, gear boxes, limit switch boxes, and drive adaptors. Simply choose your product or category to get started.

Our actuator range

You’ll find a full selection of 90-degree actuation solutions for quarter-turn valves, with all the accessories to match.

Electric actuators

These plug-and-play units are ideal for sites without air supply. Available in standard, modulating, spring return, and explosion-proof models.

Pneumatic actuators

Reliable and fast-acting, our pneumatic valve actuators are available in both double acting and spring return pneumatic types. Perfect for high-cycle and safety-critical tasks.

Rotary actuators

All our pneumatic and electric options are rotary actuators, making them ideal for ball, butterfly and plug valves.

Accessories and adaptors

Complete your setup with limit switch boxes, gearboxes, mounting brackets, and drive adaptors that fit most valve stem configurations.

Our actuators are meticulously crafted to adhere to the highest industry standards, delivering unmatched reliability and durability.

FAQs about our actuators

  • What does an actuator do?

    An actuator moves a valve open, closed, or to any point in between. It receives a signal from your system and turns that into mechanical motion — typically 90 degrees for quarter-turn valves.

  • What’s the difference between electric and pneumatic actuators?

    Electric actuators use power to drive valve movement. They’re great for remote or standalone systems.

    Pneumatic actuators use compressed air, offering fast, reliable action in high-cycle environments.

  • What is a double-acting actuator?

    A double-acting pneumatic actuator uses air to move the valve in both directions — open and close. It’s efficient and ideal when a fail-safe shutdown isn’t needed.

  • When should I choose a spring return actuator?

    Go with spring return when you need the valve to automatically return to a safe position if air or power is lost. It’s a common setup for fail-safe operation.

  • What type of actuator is best for modulating control?

    Use a modulating electric actuator if you want smooth, variable control from an electrical signal.

    Pair a pneumatic actuator with an electro-pneumatic positioner to achieve modulating control using air pressure.

  • Can I automate a manual valve?

    Yes. With the right brackets, adaptors and gear boxes, most manual valves can be upgraded with an actuator. We stock everything you need to get it done.

  • What is a limit switch box?

    A limit switch box gives feedback on the valve's position. It’s essential for remote monitoring and system integration.

  • Do you supply actuators for hazardous areas?

    Yes. We stock IECEx-rated electric actuators and limit switch boxes designed for use in hazardous or explosive environments.

  • What is a rotary actuator?

    A rotary actuator turns the valve, usually 90 degrees. This makes it the go-to choice for quarter-turn valves, such as ball or butterfly types.
