Bettis RPE-Series Pneumatic Rack and Pinion Valve Actuator
Description:
The Bettis RPE-series is a rack & pinion actuator, available in 12 sizes as spring return or double acting models. The actuators have a tough and reliable design and are intended to operate quarter turn valves or any other quarter turn application. The Bettis RPE-series comes with coated body and endcaps, has a special high corrosion resistant aluminum pinion design and has stainless steel fasteners, resulting in a long lasting durable actuator design.
Features
- Heavy duty body castings provide maximum protection in the harsh environment of process plant locations.
- Polyurethane powder coating provides excellent corrosion resistance on housing and end caps.
- One piece blow-out proof, pressure balanced, pinion allows safe in-field re-configuration from Fail-Close to Fail-Open.
- The aerospace type alloy 7075 T6 for the pinion, provides the best combination of corrosion resistance, high strength and a lightweight construction as well as providing protection against galvanic corrosion.
- Precision dual stroke adjustment provides accurate and intuitive end of stroke adjustment for the Open and Closed valve position.
- Low maintenance bearings for pistons and pinion.
- Accurately designed and machined components assure a perfect fit and long cycle life.
- Stainless steel or Deltatone™ coated fasteners.
- VDI/VDE 3845 (NAMUR) solenoid interface and top accessory interface.
- Dual ISO 5211 mounting patterns allow low-profile direct mounting to valves.
- Drive inserts on the valve flange make direct mounting flexible, either for square, flat head, or round with key way stems.

Bettis NG-Series Pneumatic Valve Actuator
Description:
The Bettis NG-Series is independently tested for LOCA (Loss of Cooling Accident), meets IEEE 382 standards, seismic, and various aging processes required for nuclear criteria.
Features
- Independently tested to include LOCA (Loss of Cooling Accident), meets IEEE 382 standards, seismic, and various aging processes required to meet current nuclear qualification criteria.
- Suitable for use in demanding applications requiring SIL environment
- Patented Tension-Lok device positively locks the spring module to allow its safe removal and installation, eliminating accidental release of the spring force
- PED 97/23/EC compliant to meet the stringent requirements of pressure mounting vessels
- Meets both IP66 and IP67M specifications for submergence and high pressure water deluge test and offers superior water ingress and corrosion protection
- Offers multiple configurations, with a modular design that enables safe field maintenance and reduced inventory costs
- Interchangeable power and spring modules for quick reversal of the fail-safe mode
- Suitable for use in demanding applications requiring SIL environment
- Corrosion resistant, and internal and external surfaces are coated to protect in harsh environments
- Offers a variety of mechanical and manual overrides for G-Series models
- Adds an extra measure of versatility with its field serviceable modular configuration – it can be altered from a single acting to a double-acting and add a hydraulic manual override after installation
- Offers complete valve operating system (VOS) for final valve control by combining the G-Series actuator, controls and a valve in a singular system.

Bettis SCE300 Electric Actuator
Description:
The SCE300 is an intelligent quarter-turn electric actuator from the Bettis family of actuators. Compact and lightweight, this all-in-one actuator fits all the features of larger, heavier actuators into a neat, innovative design. Deploy the SCE300 to maintain effective control of low-torque, quarter-turn valves and dampers in even the largest and most complex plants.
Features
- Separate terminal enclosure is kept isolated from the electronics and motor compartment; only the wiring terminal is exposed during field installation
- Standard adjustable torque switches, from 50 to 100% of rated torque output (3 steps: 50% – 75% – 100%)
- Manual override is always engaged
- Anodized aluminum with epoxy powder coat to protect unit against the decaying effects of aggressive environments
- Visual mechanical position indicator for accurate visual reference of valve position
- Directly mountable or readily adaptable to other quarter-turn valves
- Permanently-lubricated, self-locking gear train helps eliminate the need for motor brakes; Epicyclical gearing ensures reliable and smooth operation
- Mechanical travel stops designed to prevent over-travel during hand wheel or motor operation
- Over-temperature motor thermostat
- Integral speed control, independently adjustable in opening and closing directions
- Latched-type output contacts for fully open / fully closed remote indication. Output contacts for monitor and blinker/local selector indication are also available
- Optional modules add even more functionality and intelligence:
- OM1 – Modulating Input/Output module
- OM3 – Local Interface module
- OM9 – PROFIBUS DP V0/V1 bus communication
- OM11 – DeviceNet bus communication
- OM13 – 3-wire module
