Explosion Proof Electric Actuators for Oil storage application

In this article we’re taking a look at the latest STX and SQX range of explosion proof electric actuators from BERNARD CONTROLS and their application on the oil storage installation of French company Raffinerie du Midi – GPSPC.

An electric actuator offers command and control over the opening and closing of industrial valves and dampers. Depending on the application, it can operate the valve for complete opening and closing, or regulate a flow more or less intensively and precisely.

BERNARD CONTROLS designs and manufactures electric actuators and control technologies for the automation of industrial valves and dampers. They control the product along its operational lifetime, with support from the design stage to installation - and then for maintenance and repair - to ensure the most economical and reliable solution.

Explosion proof Electric Actuators

In June 2013, BERNARD CONTROLS were commissioned to supply more than 30 explosion proof actuators, from their STX and SQX ranges, on the oil storage installation of French company Raffinerie du Midi - GPSPC in Saint-Pierre-des-Corps (North West France).

 Electric Actuators with Intelligent Control

A partner for more than 20 years, GPSPC needed retrofitted electric actuators on its East and West oil depots. BERNARD CONTROLS willingly replaced 31 old explosion proof SR and ST models with new STX and SQX INTELLI+ actuators (intelligent integrated control) equipped with PROFIBUS DP interface, and also upgraded six STX with new PROFIBUS DP interface.

Their technicians were also on hand with technical support regarding fieldbus installation, in collaboration with the PLC supplier, as this fieldbus was cabled with fiber optic cables between the two depots; because of long distance and to avoid interferences with some pumps. Compared to metal wires, those plastic or glass cables carry light signals over longer distances and far more efficiently thanks to minimum loss and no sensibility to electromagnetic interference.
