Actuators are used for the automation of industrial valves found in all kinds of technical process plants including wastewater treatment plants, power plants, refineries etc wherein they play a major role in automation process. The valves to be automated vary both in design and dimensions. The diameters of the valves range from a few inches to a few meters. Depending on their type of source for operation, the actuators may be classified as pneumatic, hydraulic and electric actuators. Application: B Torq is a pneumatic quarter turn actuator with rack and pinion design to actuate any quarter turn valve such as: Butterfly valves. Ball valves. Plug valves. Media : Instrument Air / Nitrogen. Air pressure range : 2 bar to 10 bar.
