Valve Actuation Framework

The exclusive agreement, described as “amongst the most prestigious contracts available to manufacturers such as Rotork”, runs for a minimum period of three years. 

IQ and IQT Actuators

The majority of actuators involved will be IQ and IQT models, of which Thames Water now has a huge installed base.Thames was amongst the first of the UK’s water companies to embrace Rotork’s IQ ‘non-intrusive’ intelligent actuator technologies when first launched in 1993.  Rotork’s two-wire control capabilities, particularly regarding Profibus networks, were also important contributors to the Thames Water decision.

Profibus-enabled

The attached photograph shows Rotork IQ actuators on the inlet penstocks at Reading Sewage Treatment Works, a new-build project recognised as one of Thames Water’s flagship sites.  Approximately 150 Profibus-enabled IQ and IQT actuators control the sequence of sewage treatment through the works, from the fully enclosed inlet screens to the tertiary filters.
