Rotork IQ range intelligent electric actuators have been selected to operate “the largest ball valves every supplied into Asia Pacific,” according to Mr Paul Moir of the Asean Council on Petroleum (ASCOPE) in Kuala Lumpur. A total of six of these 50-inch, Class 150 valves have been supplied to Interbeton-McConnell Dowell JV for the VLCC Jetty project in Singapore. They are operated by a combination of Rotork IQ actuators and Exeeco IW10R worm/spur gearboxes, providing opening and closing times of 56 seconds. In addition, six IQ actuators and Exeeco MTW gearboxes were selected to operate 6 inch 3-way ball valves.
On the same project, which involves the construction of a complete new offloading jetty at the Exxon Singapore Refinery, twenty-four Rotork IQ actuators have also been supplied to operate through-conduit 16 inch, Class 150 gate valves. Eight of these actuators have been supplied with Rotork’s factory-fitted K-Mass fireproofing, which enables them to operate in emergency conditions at temperatures in excess of 1000°C. A further eight IQ actuators with K-Mass were supplied for the operation of 2 inch and 8 inch gate valves on the new plant.
