Thousands of Rotork electric actuators installed at Chinese oil refinery

More than 2,500 Rotork IQ3 electric actuators have been installed at a Chinese oil refinery and petrochemical complex.

Zhejiang Petroleum & Chemical Company Ltd, which refines oil and manufactures chemical products, ordered the actuators for the refinery which is in construction on the island of Zhoushan, near Shanghai.

The actuators operate gate valves, ball valves and butterfly valves to control the flow of crude oil and product oil at the plant.

Zhejiang Petroleum & Chemical Company Ltd also purchased IB multi-turn bevel gearboxes which provide a torque range up to 8,135 Nm (6,000 lbf.ft) and a thrust range up to 1,320 kN (296,750 lbf.ft).

Zhejiang Petroleum & Chemical Company Ltd, which also offers oil storage and transportation services, says Rotork’s reputation for quality as well as the reliability and stability of the IQ3 were key in its decision to buy from the business.

Rotork’s intelligent IQ3 electric multi-turn electric actuator allows the user unprecedented access to a wealth of data to maximise plant efficiency. Available in 1-phase, 3-phase and direct current variants, the IQ3 relays real-time information on an advanced dual stacked display which can be accessed even in the event of a power outage. The IQ3 provides a torque range from 10 to 3,000 Nm with a direct drive and up to 44,000 Nm when combined with an IS or IB gearbox.

When complete the entire project will feature two refineries capable of producing 400,000 barrels a day and two ethylene plants capable of producing up to 1.4 million tonnes a year.
