Innovative Hydraulic Solution for Testing Application

Actuator Tester

Resistive torque isn’t just fun to say – it’s a necessary element in many industrial testing applications.

A customer contacted us needing a resistive torque range of 2,000 to 20,000 lb-in for an important application: product life-cycle testing for electric valve actuators used in the gas industry.

To deliver a suitable solution, we had to deploy our industrial automation and testing expertise – plus a bit of out-of-the-box thinking.

The Challenge

This customer is an organization responsible for developing standards that help influence safety, product performance and the environment. The customer wanted to perform product life-cycle testing on electric valve actuators used in the gas industry.

They needed a simple, reliable and relatively low-cost method of providing a resistive torque to the electric valve actuators during cycling, with a resistive torque range of 2,000-20,000 lb-in. The maximum cycle rate for the electric valve actuators would be 90 degrees rotation in 20 seconds.

The Solution

Stanley M. Proctor Co. designed and delivered a solution that utilized a hydraulic rotary actuator in an unconventional way…
