Rotork GO (gas-over-oil) actuators have been upgraded to provide a more compact and highly reliable solution for automating heavy-duty valve applications found in the gathering, pipeline transmission, compression, and storage of gas. The new generation of GO actuators is designed for service in harsh environments with a minimum of maintenance. The improved modular design is lighter, more compact, and incorporates advanced changes to functional specifications. The standard operating pressure range is 10-105 barg (145-1,500 psig), enabling a quarter-turn operating torque of up to 600,000 Nm and linear thrust of 5 million N. Higher torque and thrust outputs also can be provided. The product is available with versions having ATEX/CE Ex or UL/CSA hazardous area approvals. Other approvals are available upon request.
