3.3.2 Electric Motor Actuator/Operator

1. Electric motor driven, comprised of a worm gear unit driven by the primary helical gear operator. All drive gears and sha�s shall be metallic. The torque switch shall be bi-direc�onal and actuated by the axial displacement of the prime mover worm sha�. The prime mover worm shall not be integral with or common to the motor rotor sha�.

Switch contacts shall be silvered plated. Motor 120/208 VAC, 3 phrase, 60 Hz. Enclosure shall be NEMA IV (weatherproof), or beter. The operator shall contain adjustable torque switches for open and closed posi�ons.

2. The operator shall be permanently lubricated, with corrosion protected or stainless steel hand wheel which is capable of being locked in both open and closed posi�on.

3. The operator shall mount directly to valve without the use of external linkage. Operator shall be pre-mounted to the valve when delivered to NASA.

4. The operator shall be furnished with an integrally mounted reversing controller.

5. The operator shall develop sufficient torque to fully open the valve against full design differen�al and fully close against flowing condi�ons (from either direc�on). Stroke �me (fully open to fully closed or fully closed to fully open) shall be no longer than 90 seconds.

6. The operator shall be capable of declutchable manual opera�on. A metallic handwheel shall be provided for manual opera�on with an arrow to indicated “open” rota�on.

Required hand wheel pull shall not exceed 80 foot-pounds. The handwheel shall not rotate during motor opera�on. A fused motor shall not prevent manual opera�on.

When in the manual opera�on mode, the actuator will remain in this mode un�l the motor is energized, at which �me the actuator will automa�cally return to electric opera�on. Movement from motor opera�on to handwheel opera�on shall be accomplished by a posi�ve padlockable declutch lever which mechanically disengages the motor and related gearing. It shall be impossible for simultaneous manual and motor operator to occur. Fric�on type declutch mechanism is not acceptable. An override shall be provided to prevent actua�on during opera�on.

7. Limit switches: Eight limit switch contacts shall be installed to func�on as follows:

a. Two contacts closed on valve full-open posi�on

b. Two contacts closed on valve full-closed posi�on

c. Two contacts open on valve full-open posi�on

d. Two contacts open on valve full-closed posi�on

8. The minimum electrical ra�ng for the limit switches shall be 5 amps @ 125 VAC. At the customer terminal strip, a Form C open and a Form C closed limit switch shall be available for remote open and closed commands. Switch design shall permit visual verifica�on of the switch posi�on without disassembly.

4) to the actuator.

a. Include indica�on lights:

i. Blue-Closed

ii. White – Open

b. Include reversing starter. Control voltage shall be 110 volts (110VAC).

Transformer to supply control power is not required, Government to supply 110VAC control power to the actuator.

c. Overload relays

d. Jogging capability

10. The electric operator shall be sized to provide a torque of 1.5 �mes the maximum torque required by the valve manufacturer to fully open and close the valve. The torque required by the manufacturer will be based on the required body pressure ra�ng as given in these specifica�ons.

11. The actuator shall have a built-in device, incorporated in the power train and located between the worm gear and actuator drive sleeve, to permit load impact under dynamic efficiency condi�ons, with a hammer blow effect, to allow the motor to reach full speed before engaging the valve load.

12. The electric motor shall be “thermally protected” to insure a safe motor shutdown during high current draw/high temperature condi�ons. The motor shall be specifically designed for valve actuator service and shall be of high star�ng torque, totally enclosed, non-ven�lated construc�on. Motor insula�on shall be a minimum NEMA Class F, with a maximum con�nuous temperature ra�ng of 155 degrees C (rise plus ambient) for the duty cycle specified. The motor shall be of sufficient size to open or close the valve at the maximum rated load. The motor shall be capable of opera�ng at plus or minus 10% of specified voltage. The duty ra�ng shall be sufficient for one complete cycle (open-close-open or reverse) without exceeding its temperature ra�ng. Motor bearings shall be of the an�-fric�on type, and permanently lubricated. The motor shall be an independent sub-assembly such that the power gearing shall not be an integral part of the motor assembly, to allow for motor or gear charges dictated by system opera�on requirements. The motor shall be equipped with internal thermal contacts and current overload contacts with manual reset to protect against motor overload. Overload protec�ve contacts shall be placed in the power source hot side of the circuit, not in the neutral side.

13. An external disc posi�on indicator shall be provided which is clearly visible a�er valve installa�on.
