GE Oil & Gas Becker* Rotary Piston Double Acting (RPDA) Heavy -duty, high performance applications require RPDA Actuators
Becker RPDA Rotary Piston Double Acting Actuators from GE Oil & Gas are ideally suited for operations that demand a lock last failure mode, including below ground regulation and bleed-to-pressure applications. These long-lasting, compact, durable, and maintenance free actuators can be retrofitted onto almost all pipeline valves. RPDA Actuators are built to accept high pressure power gas and can incorporate options that eliminate emissions and economically reduce below-ground noise.

Less ambient heat loss ■■ May use smaller adjacent piping diameter ■■ Smaller station footprint ■■ Most economical noise attenuation ■■ May eliminate need for buildings/enclosures by utilizing the fiberglass cabinet Figure 11 - Installation of Becker Below Ground Regulators (Prior to Backfill) A large natural gas transmission/distribution company based in Southern California installed Becker Below Ground Ball Valve Regulators to achieve maximum noise attenuation, minimal maintenance, and optimum co
Accessories GE’s Becker Control Valve Actuators provide reliability and accuracy for all of your control valve applications Limit Switches Limit switches provide an indication of valve status and are commonly utilized on both on-off and control valves. A limit switch assembly will close a contact at both the full-open and at the full-closed position of valve travel. The switches provide a remote indication to gas control, RTU or a flow computer as to the status of a valve.
