THINKTANK Pneumatic Linear Valve Actuator

In recent years, we’ve worked closely with manufacturers of wedge gate valves, slab gate valves, knife gate valves, globe valves, and rising stem plug valves. One recurring request stood out:

“Can you provide a reliable pneumatic linear actuator that fits our custom valve dimensions, with enough thrust and flexible control options?”

At the same time, some end users faced a different issue.

Their existing actuators had failed after years of service, but replacements weren’t easy to find. The original suppliers were gone, or the actuator specs had changed.
They needed a custom actuator to match existing mounting sizes, stroke, and control logic—without modifying the whole system.

Many of our OEM partners were looking for actuators that could deliver strong thrust, were built to last, and could be easily adapted to different valve designs—even in small production runs with custom specs.

Why We Developed Pneumatic Linear Valve Actuator

To meet that need, we developed the THINKTANK Pneumatic Linear Valve Actuator — a modular, reliable solution designed to fit a wide range of rising stem valves.

We created this product line with two goals in mind:

• To support valve manufacturers who need tight mechanical and control integration
• And to help end users who need custom-built actuators to replace legacy units in the field — without changing the valve or piping

Type of Pneumatic Linear Valve Actuator

a. Single Acting Normally Closed Pneumatic Actuator (FO) (Model SAC Series)

b. Single Acting Normally Open Pneumatic Actuator (FC) (Model SAO Series)

c. Double Acting Double Cylinder Linear Pneumatic Actuator (Model DAD Series)

d. Double Acting Single Cylinder Linear Pneumatic Actuator (Model DAS Series)

Note: The above values represent the thrust of single cylinder pneumatic actuators. For double cylinder actuators, the thrust is approximately twice that of single-cylinder models.
