RPDA high pressure actuator built solid for all your control valve needs Bleed to Pressure System* Can Eliminate Bleed Gas Emissions Below Ground Actuator Option Reduces Noise Attenuation up to 37 dBA GE’s Becker RPDA Actuators feature the unique ability to incorporate the Bleed to Pressure System feature. GE’s Becker RPDA Actuators and control instrumentation can accept high pressure power gas and discharge bleed gas to lower pressure systems.Bleed to Pressure Systemeliminates all atmospheric emissions! Becker RPDA actuators are available with a unique below ground option that provides superior noise attenuation in regulator stations at minimal cost. Additionally, below ground stations minimize ambient heat loss by maintaining piping systems below ground. Maintenance Free The RPDA actuator is designed to be maintenance free, no regular lubrication is required for the piston cylinder or the actuator mechanism. High Pressure Capability The RPDA actuator is specifically constructed to accept high pressure natural gas up to 500 psig (3448 kPa). Higher pressure power gas allows use of smaller actuators and implementation of Becker products’ unique Bleed to Pressure System. We can retrofit to almost any valve in your pipeline We can provide high quality actuators to mate to almost any quarter turn valve, regardless of manufacturer or age. We have years of experience successfully adapting our actuators to fit a multitude of valves. U-Cup Seals U-cup Piston Seals are designed to provide superior sealing capabilities with minimal friction. This design allows accurate positioning of the control valve actuator with very slight pressure differential to the piston. Vertical Advantage Upright actuator promotes longer actuator piston seal life, saves space, and requires less maintenance than other actuators. Easy to Read Travel Indicator All RPDA actuators come equipped with a precision linear scale that indicates valve position in ten percent increments. Crank Arm Designed for Control Valves Crank arm design actuators are specifically suited for control applications. The crank arm provides an increasing torque curve that develops high torque output where it counts. Additionally, the crank arm design minimizes friction and lost motion. Torque Arm Bearings RPDA Actuators feature two large Torque Arm Bearings to eliminate side load to control valve stem. Both inboard and outboard torque arm bearings are manufactured from non-metallic Duralon™ material to ensure maximum load bearing capacity. Duralon is a registered trademark of Rexnord, Inc.

The Below Ground Regulator can provide up to 37 dBA additional noise attenuation with minimal additional cost. Two different size Below Ground Ball Valve Regulators are show here. 16” Bore Below Ground Regulators are shown in background, while 30” bore Below Ground Ball Valve Regulators are shown in foreground. The Below Ground Ball Valve Regulators are shown during installation, prior to backfill of the regulator station. 37 dBa 30 dBa 25 dBa 20 10 6 ft Depth ■■ 30 5 ft Depth More than 25 dBA noise attenuation 35 dBa 4 ft Depth ■■ 40 3 ft Depth The Becker Below Ground Ball Valve Regulator option is unique to GE and provides a multitude of benefits by direct burial of the control valve. The valve actuator, lubrication lines,and drain lines are extended above ground while the ball valve remains below ground. The primary advantage of Becker Below Ground Regulators is inexpensive noise attenuation in excess of 25 dBA. Additional Noise Attenuation Noise Attenuation (dBa) Below Ground Regulator Options 0 Below Ground Depth (ft.) Figure 10 - Below Ground Noise Attenuation Compared to Depth. Typical below ground depths range from 3 feet to 6 feet burial. The below ground depth is measured from centerline of pipe to ground. Below ground usually provides from 25 dBA to 37 dBA noise attenuation Figure 12 - Installation of Becker Below Ground Regulators (After Backfill) The customer was able to achieve up to 25 dBA noise attenuation over conventional above ground control valves with minimal costs. The RPDA actuator utilizes an extended linkage to throttle the control valve below ground. Many GE customers have utilized the below ground concept for many years with great success and minimal maintenance. The topworks of the control valve actuators are enclosed with Becker CAB Series Fiberglass Cabinets (green) after backfill of regulator station. 16” Below Ground Ball Valve Regulators are located at left, while 30” Below Ground Ball Valve Regulators are located at right. A masonry wall has been installed at the perimeter of the station. Upstream station isolation valves are located in the foreground of the picture. 13 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. Limit switch assemblies are available with a variety of configurations. Housing Switches Option NEMA 4, 4X, 7, Class I, Groups C & D, Division 1 & 2 2 or 4 2 or 4 Hermetically Seales Switches SPDT Single Pole, Double Throw DPDT Double Pole, Double Throw up to 125 V D.C. at .5 amps up to 250 V A.C. at 15 amps Position Transmitter The Valve Position Feedback assembly provides a quantitative indication of the exact position of a control valve. The Valve Position Feedback assembly provides 4-20 mA analog remote position feedback proportional to the control valve position. The feedback signal may be utilized as an integral portion of the control loop or merely as an additional feedback signal to gas control for monitoring valve status. Valve Position Feedback is typically utilized on flow control valves Transmitter Housing Switches Option 4-20 mA Output NEMA 4, 4X, 7, Class I, Groups C & D, Division 1 & 2 2 or 4 2 or 4 Hermetically Seales Switches SPDT Single Pole, Double Throw DPDT Double Pole, Double Throw up to 125 V D.C. at .5 amps up to 250 V A.C. at 15 amps Trip Valve The Trip Valve protects double-acting actuators from loss of supply gas pressure. In the event that the supply gas pressure falls below a minimum level, the trip valve can be configured to do one of the following: lock the valve in last position, stroke the valve to the full-open position*, Stroke the valve to the full-closed position* *These applications require an additional volume tank to perform the operation Max Allowable Weight Body Connections Temp.

Size based on application Hydraulic Operator override The Hydraulic pump override is utilized for manual operation of large control valves when pneumatic power is not available. The Hydraulic pump override utilizes a hydraulic pump and reservoir to develop necessary torque to close/open the control valve. Hydraulic pump overrides are typically utilized on ball control valves larger than 16” bore. 14 Let GE help select the perfect rotary control valve actuator • LD LPDA (Large Models • LPSR LPDA (Small Models) SYSR RPSR SYDA (Large Models) SYDA (Small Models) RPDA (Large Models) RPDA (Small Models) Table 8- Selection table for Becker Control Valves and Actuators GE has a wide variety of control valve actuators with a variety of features that ensure the optimum solution for your application needs.
