The acquisition of Ralph A. Hiller Company (Hiller) enables Rotork 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 US 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 supports its actuation products with a stock of factory original parts to ensure a swift response to the demands of safety related applications. Maintenance, field service and training are also provided, together with a comprehensive refurbishment service for complete hydraulic and pneumatic systems. 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.
Alex Busby, Rotork Fluid Systems managing director, explains: "The acquisition of Hiller will enable Rotork to establish a centre of excellence for nuclear industry products. As well as being a significant addition to Rotork Fluid Systems, Hiller is also a key element in the completion of our portfolio of Rotork products."
