ATI Hydraulic Hand Pump

Performance Highlights




The ATI Hydraulic Hand Pump provides an efficient back-up system for opening and closing valves when power gas for pneumatic actuators or power hydraulic fluid for hydraulic actuators is not available. Utilizing a balanced piston design eliminates the possibility of cavitation or creating a vacuum because the pressure on either side of the piston is always equal and both cavities are always full of oil. The high flow capacity provides easy and efficient manual opening and closing of even the largest valves.

Typically hand pumps on pneumatic actuators will have a self-contained reservoir while hand pumps on hydraulic actuators will share the same reservoir as the power unit.

The Hydraulic Hand Pump includes an automatic reset function on the open/close selectors to prevent inadvertent movement of the pump handle when power gas or power hydraulic fluid is re-introduced. This feature automatically resets the pump to the neutral position when gas pressure or hydraulic pressure is detected.

A pressure relief button is provided to relieve any internal pressure after pumping is complete. This allows the pump ram to be retracted into the pump, out of any hostile atmosphere.

Our Client


I have to say, we looked at the valves and the actuators this afternoon and they are very well packaged and presented. I want to thank ATI for the attention this order has clearly received & I plan to pursue similar solutions in the future with you guys.


In all of the readiness reviews that I have conducted, ATI is by far the most well-prepared. The organization has built a solid foundation, and is off to a healthy start to the new [ISO 9001:2015] standard; ATI has clearly taken a serious approach to addressing the risks of its business and handling mitigation in a controlled manner.

ATI linear actuators on 6-inch and 8-inch gate valves have worked flawlessly since put in Y-grade liquid service in 1994.

George Ford, Engineer, Enterprise Products

I was impressed and quite thankful for ATI’s commitment to get the job done on time and with a high level of quality.

Konrad M. Fontenot, Engineering Section Group Lead, Exxonmobil Beaumont

ATI has been supportive when we have had questions and their product has worked well for us. If the application came up again where we had the choice of using the ATI actuators, I would recommend getting them.


All of our switching valves for our mole sieve beds are orbit valves fitted with ATI actuators. These have been in service for ~8 months now and have had no issues.


ATI was very supportive during this project with helping us when we had to retrofit the actuators to the valves during a quick series of valve replacements.


We have 14 of your actuators at this facility, with a clean rack record for over a decade.

I really appreciate the commitment to deliver the needed products on a very short schedule.
