Rotork Fluid System has built Rotork’s largest ever pneumatic actuator, for delivery to a pipeline project in Thailand. The model GP350 spring return actuator will operate a 42in Class 900 Cooper Cameron ball valve to provide mainline shutdown duty on the Third Transmission pipeline onshore project, constructed for the Thailand Oil and Gas Authority. Designed to close the valve in 30 seconds, the GP350 actuator provides a massive break torque of 533,000Nm and 155,000Nm of spring end torque. It has been supplied together with sixteen other model GP actuators designed to operate Cooper Cameron 30 inch and 36 inch Class 300, 600 and 900 ball valves. The Thailand Oil and Gas Authority project involves the construction of a third main pipeline route, from Rayong to Bang Pakong, which will facilitate additional gas supplies and secure higher gas distribution capacity in the future.
