Hiller® Celebrates 60 Years of Innovation

Trillium Flow Technologies™ Hiller^® brand is celebrating its 60^th anniversary.

With decades of OEM experience in the commercial nuclear power generation industry, Hiller^® is renowned globally for high-quality valve actuation products and support services. The brand’s nuclear industry-focused team designs, manufactures, and services products for all pneumatic, hydraulic, electro-hydraulic, and electric actuation applications.

Founded by Ralph A. Hiller in 1950 as a distributor for multiple fluid power products, Hiller^® designed its first valve actuation products in 1962. From 1966, its actuators were supplied for use in commercial nuclear power plants.

In 1972, the brand’s Main Steam Isolation Valve (MSIV) actuator was successfully tested by the Institute of Electrical Engineers (IEEE). Further testing for the 38-inch MSIV actuator followed in 1976.

In the 2000s, Hiller^® achieved qualifications for its Advanced Boiling Water Reactor (ABWR) and NGC and NGP product ranges.

When Trillium Flow Technologies ™ was founded in 2019, Hiller^® became an official part of the Trillium Flow Technologies™ family of legacy brands.

Based in Pittsburg, Pennsylvania, USA, Hiller^® products include LP/LH linear pneumatic and hydraulic actuators, NGP/NGH 1/4-turn pneumatic and hydraulic actuators, and NGC gas-charged hydraulic actuators, which are typically used for main steam isolation and main feedwater isolation valves.

“I am incredibly proud of our journey from a small operation to a global OEM leader. This milestone is a tribute to our dedicated and innovative team, and the unwavering support of our customers and partners. “As we look to the future, our commitment to excellence and innovation remains stronger than ever. We hope to accelerate growth into the small modular reactor market in 2025.”
