The Company was established as a small engineering workshop in Bristol in the 1940s. In 1945 it was acquired by Frenchay Products led by Jeremy Fry under whose leadership it made its first actuator in 1952. It was first listed on the London Stock Exchange in 1968 as Rotork Controls.
In 1999 it bought Fluid System Srl, an Italian actuator business, in 2000 it bought Skilmatic in Leeds and in 2002 it acquired Jordan Controls, a United States actuator business. It started operating in Sweden in 2008 with the purchase of Remote Control.
In 2009 the company went on to buy Flow-Quip, a United States-based business. Then in 2010 it acquired Ralph A. Hillier, another American business. In 2011, Rotork Servo Controles de Mexico S.A. de C.V. became fully owned by Rotork after being part-owned since the 1970s.  Shortly after Rotork purchased Valco Valves Automation AS, Rotork’s long term sales and service agent in Norway, now renamed Rotork Norway.  Rotork has also acquired K-Tork International Inc. based in Dallas and Centork Valve Control S.L., a Spanish actuator manufacturer based near San Sebastián. 
In 2011 the acquisition of Fairchild Industrial Products in North Carolina heralded the creation of the Rotork Instruments division and in the UK Prokits was purchased and merged with Rotork Valvekits.
In 2012 Italian switchbox manufacturer Soldo Srl was added to Rotork Instruments and in 2013 the German actuator manufacturer Schischek was purchased.
Flowco in the UK and Renfro associates in the USA were further acquisitions in 2013 - both adding to the company’s service capabilities – and the Italian actuator manufacturer GT Attuatori Srl was also purchased. In 2014 Rotork Instruments was strengthened with the acquisition of Young Tech Co. Ltd. (YTC), a highly respected Korean instrumentation manufacturer.
The company is a designer and manufacturer of industrial flow control products encompassing valve actuators, gearboxes, control systems, instrumentation and accessories. It is organised into the following businesses: Rotork Controls, Rotork Fluid Systems, Rotork Gears, Rotork Instruments. Rotork Site Services supports all these divisions.
