Actuators for remote gas pipeline applications

Twenty Skilmatic EH electro-hydraulic failsafe actuators have been supplied by Rotork Fluid Systems at Calgary for remote gas pipeline applications in northern Alberta. Requiring a 24 V d.c. power supply, these actuators are designed for low temperature service down to -40C and equipped with solar powered battery packs to facilitate reliable operation even in harsh, sub-zero temperature conditions. The completed actuated valve packages, including the solar power and satellite communication systems, were fabricated by Rotork distributor Apex and supplied to energy company Encana for their Huron Energy project.
