We see from your search that you're looking for information on the term "Electric Valve Actuators",
and we have a large number of manufacturers' news releases and technical articles here on Engineeringtalk which will be of interest.
Let me be your guide.
Start with
the news release Actuators cut maintenance costs for sewage plant from
Rotork Controls, which we summarised at the time by saying "Fourteen RGF and twenty GAC filter beds at the water treatment works has been retrofitted with Rotork IQ multiturn actuators and IQT direct drive quarter-turn actuators".
A few weeks before,
we featured the news release Half-turn actuators are a welcome addition from
Radius: "Pneumatic valve actuator is designed for valves that require 180-degree operation but must stop in the mid-point on loss of air pressure".
In October 2007, we covered the news from Rotork Controls
concerning its Rotork A, AQ and IQ actuators
- take a look at Double-sealed actuators survive flooding
which says: "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".
Take a look also at the news release from Rotork Exeeco, Valve actuators chosen for desulphurisation plant,
as well as Wessex Water chooses valve supplier from Rotork Controls,
and Strategic pipeline includes hundreds of actuators from Rotork Controls.
