GE Oil & Gas launched the CHA Hydraulic Actuator Series at the Offshore Northern Seas (ONS) Conference and Exhibition, held in Stavanger in August last year
Since its acquisition of the John Wood Group PLC Well Support division in 2011, GE has been supplying customers with the RA Series of actuators product line, a reliable, cost-effective solution capable of managing supply pressures up to 3,500 psi. GE's new CHA Series exceeds the RA Series by accepting supply pressures up to a maximum of 6,000 psi.
"With our new CHA Series, GE now provides a more robust line of actuators," said Ian Milne, president of the GE Oil & Gas Pressure Control business.
"This introduction increases our market competitiveness, as we continue to provide a full array of products with added-value services. We believe the CHA Series offers key features that will appeal to operators who are concerned with increased safety."
Improved safety features offered by the CHA Series include:
- Quick-disconnect design enables removal of the actuator from the bonnet within the valve operating stroke, without depressurizing the valve and releasing hydrocarbons.
- Powerful dual-coil spring package is capable of shearing standard 7/32" braided cable, allowing valve closure.
- A captured spring design prevents release of the preloaded spring during repair or actuator removal.
- Top access rising stem provides both a visual confirmation of the valve's position and an interface for the use of safety-related accessories.
- The CHA Series offers two large-diameter (1/2") LP actuator ports: one for easy alignment to supply lines, minimizing debris buildup and one with an optional safety head designed to protect the actuator from over-pressurization and costly repairs. Operating at a maximum supply pressure of 6,000 psi allows use of a smaller actuator and greater control system flexibility. Fewer housing penetrations prevent the ingress of dust or water for easy maintenance.
