Rotork actuators installed at Spanish plant

A total of 150 intelligent electric actuators from Rotork have been ordered for the Quimica Puente Mayorga processing plant.
The plant in Cadiz, Spain, is owned by CEPSA, a Spanish multi-national oil and gas company with operations throughout Europe.
Some of Rotork’s IQ range of intelligent electric actuators have already been installed - the remainder are to be installed in the coming months.
The actuators were installed on gate valves and control the flow of unprocessed fluids, as well as providing Emergency Shutdown (ESD) functionality.
In an emergency, they release the fluids into suction and discharge pumps for isolation.
The actuators have been installed on a double loop system with a Rotork Master Station on a Pakscan control network.
The installation of this control network has enabled CEPSA to reduce their wiring costs at the Quimica Puente Mayorga plant.
This was achieved using a single twisted pair, rather than having to depend upon an expensive multicore cable.
This was also a cost-efficient solution due to the short commissioning time of the product and the increased plant productivity that Pakscan can provide. Additionally, with one cabinet acting as an access point to over 240 field devices within a 20 km loop, it helps to prevent the spacing issues which control cabinets might otherwise create.
