R.A Hiller

RA Hiller is a global supplier of valve actuators for the commercial nuclear power generation industry. Our nuclear industry focused team designs, manufacturers, and services products for all pneumatic, hydraulic, and electro-hydraulic actuation requirements including both linear and rotary applications. The products have an extensive installed base in safety and non-safety related applications in nuclear power plants utilizing either pressurized-water or boiling-water type reactors. Founded outside of Pittsburgh, PA, USA in 1950 as the Ralph A. Hiller Company, the initial focus was distribution of various flow control products. The business quickly evolved to design and supply of the first actuation products for the commercial nuclear power industry in 1966. This evolutionary design methodology is still being applied today to develop innovative new flow control products for Generation III Nuclear Power Plant designs and beyond. RA Hiller is a fully owned subsidiary of Trillium Flow Technologies TM, headquartered in Houston, TX. The RA Hiller product offering complements the already well-established nuclear industry focused Trillium Flow Technologies portfolio.
