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.[3] It was first listed on the London Stock Exchange in 1968 as Rotork Controls.[4]

Protech Instruments & Systems, an instrumentation company, was purchased in 1985 to expedite the development of Pakscan, a digital bus control system for actuators.[5]

In 1999 it bought Fluid System Srl, an Italian actuator business, in 2000 it bought Skilmatic in Leeds[5] and in 2002 it acquired Jordan Controls, a United States actuator business.[3] It started operating in Sweden in 2008 with the purchase of Remote Control.[6]

In 2009 the company went on to buy Flow-Quip, a United States-based business.[7] Then in 2010 it acquired Ralph A. Hillier, another American business.[8] In 2011, Rotork Servo Controles de Mexico S.A. de C.V. became fully owned by Rotork after being part-owned since the 1970s.[9] Shortly after Rotork purchased Valco Valves Automation AS, Rotork’s long term sales and service agent in Norway, now renamed Rotork Norway.[10] 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.[11]

In 2011 the acquisition of Fairchild Industrial Products in North Carolina heralded the creation of the Rotork Instruments division[12] and in the UK Prokits was purchased and merged with Rotork Valvekits.[13]

In 2012 Italian switchbox manufacturer Soldo Srl was added to Rotork Instruments and in 2013 the German actuator manufacturer Schischek was purchased.[14]

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.[15] In 2014 Rotork Instruments was strengthened with the acquisition of Young Tech Co. Ltd. (YTC), a highly respected Korean instrumentation manufacturer.[16]
