Linear Hydraulic Actuators
Our H & HDH series are piston operated valve actuators that use hydraulic pressure or high pressure gas to provide the force required to open, close and control rising stem valves.
Performance Highlights
- Our H series actuator is ideal for control valves especially when it incorporates the ATI hydraulic positioning system.
- Our HDH series actuator has been effectively used for on/off applications such as steam blow applications that require very fast opening speeds.
- The adaptable nature of our design allows you to automate valves in place without shutting the plant down.
Steam blow that requires a 19" gate to move in three seconds. (ATI power system in background.)
Spring Return
To provide proper failure position, ATI spring cartridges allow for fail open or fail closed valve applications.
The spring return units provide a very compact design.

Double Acting
Due to the high pressures that our hydraulic actuators accomodate, we can maximize the thrust and minimize the size of each unit.
