The Rotork GT product range adds an established design of rugged rack and pinion pneumatic valve actuators to Rotork’s comprehensive offering of flow control products.
The Rotork GT product range encompasses single and double acting rack and pinion actuators, solenoid valves, switchboxes and mounting accessories, providing packaged valve solutions for flow control applications in many industrial processes. For safety critical duties, the actuators are available with SIL3 certification to IEC international standards 61508 and 61511.
Available with torque outputs up to 15,300 Nm, the compact, anodised aluminium bodied actuators operate from air supply pressures between 2 and 10 Bar in a standard temperature range of -50ºC to +70ºC. Special seals can increase the temperature range to +200ºC.
Standard strokes of 90º, 120º and 180º, with +/-5º positional adjustment, can be increased to 240º upon application, whilst customised angles and three position versions are also available.
