Rotork’s acquisition of Ralph A. Hiller Co. Inc. (Hiller) has enabled the company to add an established range of nuclear qualified fluid power valve actuators to its existing comprehensive electric actuation capabilities in the nuclear power industry. First established at Pittsburgh, Pennsylvania in 1950, Hiller began the production of actuators for the nuclear industry in 1968. The company can now claim a large installed product base within the USA and throughout the world. Hiller’s nuclear product range encompasses rotary and linear pneumatic and hydraulic actuators, in double-acting and spring-return configurations, together with specialised linear hydro-pneumatic actuators designed to deliver very precise speed control. Applications include main steam isolation valves, feed water isolation valves, HVAC system dampers and balance of plant auxiliary systems. Quality assurance for these products conforms to 10 CFR 50 APP B, 10 CFR 21, ANSI N45.2 and has been audited by both NUPIC and NIAC. Environmental and seismic qualifications comprise IEEE 323,344 and 382. Hiller products will sit within the Rotork Fluid Systems Division and be sold through existing sales channels as well as Rotork’s worldwide network of offices and agencies.
