TorqPlus

Electric Valve Actuators and Controls

Introduction

Advantages

For more than 40 years, Bettis Corporation has been recognized worldwide for providing industry with high performance pneumatic and hydraulic valve actuators. The addition of the Bettis line of TorqPlus electric actuators carries on the tradition of product quality, innovation and service reliability.

Bettis TorqPlus actuators are specifi-

cally designed for quarter-turn operating applications — ball, butterfly and plug valves; dampers; vents and similar uses. TorqPlus actuators are available in a wide range of output torques and operating speeds to fit your specific requirements.

The Bettis Engineered Solution

Most electric actuators in use today are designed to meet a range of torque and speed requirements for use in industrial applications. Controls and optional accessories are often available, added at the factory while being assembled. Heretofore, not much attention has been given to field upgrades, inventory modifications or parts replacement during servicing.

The Bettis TorqPlus actuators, instead, provide its users with a unique modular approach. The actuators are manufactured with pre-tapped holes in the base plate to accommodate a myriad of control and accessory components, available in more than 200 easy-to-install kits to fit virtually every requirement imaginable. Kits are available, depending on the actuator model, to add:

■ Heaters and thermostats

■ Potentiometers

■ Servo controls

■ Motor brakes

■ Positioners and transmitters

■ Control stations

■ Multi-turn operation

■ PLC interface

All of the components can be added inside the CSA type 4/4x weatherproof housing or the CSA type 4/4x, 7 and 9 weatherproof/explosion proof housings.

The Bettis TorqPlus, and the modular concept, offers its users significant advantages:

■ Compact Design – The actuators provide maxi-

mum torque output relative to its small design housing.

■ Custom Control Standards – By offering an

almost endless number of control and accessory combinations, Bettis electric actuators can effectively be designed to virtually any end use.

■ Modular Construction – The modular design

allows the actuators to be easily field modified and serviced. Accessory kits can be stored for future use without consuming a large amount of storage space.

■ High Strength Gearing – We precision-machine

our gears from hardened alloy steel, and run in needle bearings. The result is efficiency, smooth energy transfer, quiet operation and, best of all, long service life.

■ Low Maintenance – Permanent lubrication

reduces the need for scheduled maintenance. The actuators are supplied with low temperature lubricant, allowing the units to perform in temperatures to -40°F (-40°C). All operational parts are fully enclosed in the housing eliminating all contact with the environment.

■ Guaranteed Minimum Torques – As with other

Bettis actuators, we guarantee that our published output torque values are minimum values. If any Bettis TorqPlus actuator fails to meet its specified torque output under normal use, we will replace it.

■ Duty Cycle – All Bettis actuators are rated for a

duty cycle of at least 30% (one motor-on period followed by two motor-off periods). Higher duty cycles (up to 100%), which can allow for up to 1200 starts per hour, at normal ambient temperatures are available.

The following information may be used as a guide to compose specifications for Bettis TorqPlus Electric Actuators. Bettis supplies Electric Actuators that meet or exceed all of the specifications stated below except the Model EM-100 (which is not equipped with a manual override feature or dual conduit entrances).

7. Torque Limit Switches

All actuators of 2,000 lb-in (226 Nm) output torque or greater, shall be supplied with two (2) mechanical torque limiting switches which shall be responsive to maximum torque encountered in both directions of travel.

8. Manual Override

Transfer to manual operation from motor operation shall not require the use of hand levers, solenoid shifters or handwheel depression and the transfer shall be positive and reliable.

Actuators of less than 1700 lb-in, except for the model 100, shall be supplied with a disengageable manual override mechanism. Disengagement of the motor drive shall permit the use of a wrench on the output shaft flats and shall by-pass the power gear drive and motor for manual operation.

Actuators of 2,000 lb-in (226 Nm) or greater output torque shall be supplied with a handwheel which will not rotate during motor operation, but must be operational at all times without danger of injury to operator. The handwheel shall not require more than 50 lbs. of rim force to operate under the most adverse conditions and be capable of assisting or opposing the motor without any form of declutching.

9. Enclosure

The actuator enclosure shall be a high-strength sand casting and must be certified by CSA*, or equal third party tester, as acceptable for use in the following locations:

9.1 Non-hazardous indoor or outdoor location to protect against wind-blown dust and rain, splashing water and hose-directed water (i.e. CSA Enclosure 4 – Weatherproof, conforms to IP-65).

9.2 Hazardous locations classified as Class I and II, Groups C, D, E, F and G as defined in the National Electrical Code plus non-hazardous locations to protect against wind-blown dust and rain, splashing water and hose-directed water (i.e. CSA Enclosure 4 and 7 – Explosion-proof and Weatherproof).

TYPICAL SPECIFICATIONS

DESIGN AND CONSTRUCTION

These very rugged and versatile electric actuators take full benefit of precision-machining which allows every model to provide maximum torque output relative to its compact design configuration and contains a minimum of parts to reduce vibration, lessen noise and resist harsh service. Utilizing a combination of spur, worm and planetary power gearing reduction systems, the Bettis TorqPlus actuators incorporate the most efficient, powerful and appropriate drive design for service excellence.

1. Motors. Available in Single Phase, 3 Phase and DC voltages, all motors are custom built for high-torque, low current draw and the highest duty cycle ratings offered. Single phase motors are capacitor run type and three phase are squirrel cage induction type both having integral self resetting thermal cut-outs.

2. Brakes. Offered for all AC and DC motors, they are capable of a holding force equal to the output torque ratings of each actuator model.

3. Heater and Thermostat. Securely mounted and appropriately sized to insure ample protection even in the worst environments (not visible in photo).

4. Terminal Strips. Standard in all models and allow

(EM-500 Series)

easy plus efficient actuator installation.

5. Capacitors. Used on all single phase AC units, each capacitor is peak voltage rated and of improved design for maximum service life.

6. Potentiometers. Precision mechanically linked to actuator output drive for continuous position signaling.

7. Position Indicator. Mechanically driven and easily viewed at top of actuator to insure or confirm actual actuator and driven device position at all times (not available on compact Model EM-100).

8. Dual Conduit Connections. Standard on all models, except EM-100, allows full electrical code access of all wiring through two NPT connections.

9. Torque Limit Switches. Standard for the hightorque 800-Series of Bettis TorqPlus actuators. These mechanical switches eliminate potential driven device damage due to over torque conditions in either direction of operation.

10.Manual Override. Standard in all models except the EM-100, manual override capability is offered in two forms; Declutchable and Direct Acting.

DESIGN AND CONSTRUCTION

(EM-800 Series)

Model EM-300 and the complete 500-Series

offer a Declutchable design which disengages the power gear drive from the output shaft. Manual operation is accomplished by rotating the exposed output shaft drive flats with an open end wrench after the position indicator knob is pulled up. Return to full automatic operation is as easy as removing the wrench and lowering the position indicator knob to allow the mechanism to re-engage upon application of power. Should power be applied during manual operation, the declutchable design will not allow the output shaft to rotate.

The 800-Series offers a Direct Acting handwheel design which allows completely safe operation at any time and with never more than 50 pounds of rim pull force. Operating independent of the motor but directly into the power gear drive, the handwheel does not rotate during automatic operation of the actuator, requires no engagement action for manual operation and may be rotated with or without power to the unit.

11.Enclosures. Made from high strength sand castings,

enclosures are rated for applications in both Non-hazardous and Hazardous locations. As an option, the Bettis TorqPlus is also available with a CSA Certified combination Hazardous and Non-hazardous enclosure for indoor and outdoor protection in locations classified Class I and II, Groups C, D, E, F and G as defined in the National Electrical Code plus protects against wind-blown dust, wind-blown rain, splashing water and hose-directed water.

12.Output Drives are corrosion resistant. Female drives are available in a variety of DIN/ISO 8-point sizes. Male drives are also available on models 300 and 500. The EM-800 series is provided with bored drive sleeve with double keyways.

13.Powder Coat Finish. A polyester external coating developed to serve as both a high durability impact and chemical resistant finish. With up to 160 lb-in ASTM D2794 impact resistance, over 1000 hours ASTM B117 salt spray rating and 1000+ hours ASTM D2247 humidity resistance, this protective finish will stay in place and do the job.
