We see from your search that you're looking for information on the term "Electric Valve Actuator",
and we have several manufacturers' news releases and technical articles here on Engineeringtalk which will be of interest.
Let me be your guide.
Begin with
the news release Double-sealed actuators survive flooding from
Rotork Controls, which we summarised at the time by saying "Rotork provided two site service technicians who inspected and checked actuators in vital areas including the low lift pump house, which had been submerged to a depth of 3m".
Several months prior to that,
we featured the news release Valve actuator raises intelligence quotient from
Rotork Controls: "The IQ intelligent electric valve actuator has been further improved with the introduction of the IQ Pro".
In October 2005, we covered the news from Rotork Controls
concerning its IQ actuator
- take a look at Actuator keeps the chocolate flowing
which says: "A Rotork IQ intelligent electric valve actuator has replaced a hydraulic cylinder in a key area of a moulding plant at Cadbury's Bournville factory".
Take a look also at the news release from Rotork Controls, Intelligent valve actuator keeps caves open,
as well as Electric valve actuator catalogue now on CD-Rom from Rotork Controls,
and UK and European valvemakers go for Rotork from Rotork Controls.
