1999 a step change in fluid power actuator business was heralded by the acquisition of Fluid System Srl, situated in the heart of the Italian valvemaking industry at Lucca. Fluid System’s product range included subsea and other specialised derivatives. Lucca became the main manufacturing plant for fluid power actuators and the range began a successive programme of review, rationalisation and development to create an unrivalled product offering.
Further investment in the Rotork Gears Division began in 1993 with the completion of the purchase of Exeeco, a gearbox company that had been part owned since 1987. A leading valve accessory company, Valvekits, was also purchased
