August 29, 2013 - Rotork delivered 82 large GP Range pneumatic valve actuators for a natural gas pipeline owned by the Gas Authority of India. Manufactured at the Rotork Fluid Systems factory in Lucca, Italy, the actuators have been supplied to valvemakers in India for installation on Phase 2 of the Kochi-Koottanad Bangalore-Mangalore Pipeline project. The actuators will operate above ground and buried service ESD (Emergency Shutdown) ball valves along the length of the 30 inch diameter, 879 kilometre pipeline, which runs from a new 5 million tonne annual capacity LNG import terminal constructed by Petronet at Kochi, on India’s south-west coast.
Rotork’s contract included packaging the actuators with cabinet mounted limit switches and controls, together with gas storage tanks for the ESD duty. GP actuators are manufactured in double-acting and spring return configurations with torque outputs up to 600,000 Nm (5,000,000 lbf-in). Certifications include IP66M/67M, ATEX94/9/EC and PED 93/27/EC and the actuators are also suitable for use in SIL2 and SIL3 rated safety systems.
