2 I Pratt Industrial
INTRODUCTION
- Pratt Industrial designs and provides high quality actuators and services related to valve automation.
- Our long years of experience in the automation field enables us to launch our ITQ series electric actuator which has compact size, robust construction, reliable performance and ability to integrate fully into sophisticated control systems.
- Pratt Industrial is always ready to provide you with our ITQ series actuator and accessories, with quality service.
FEATURES
Pratt Industrial I 3
- Compact and robust construction, light weight providing high output torque (Max 79,500in/lbs).- Wide range of torque variation (From min 800in/lbs to max 79,500in/lbs).- Hard anodized aluminum housing inside and outside with external powder coated against severe industrial environment.
- Enclosure using radial seals & O-rings that provide protection to waterproof IP67 (Nema 4 & 6) and optional watertight IP68
- Dual mounting base ISO5211 standard and KU standard.- Removable drive bushing for easy machining and mounting.- Self-locking provided by double worm gearing (no brake required).- Auto-declutching manual override handwheel with padlockable auto / manual switchable lever.
- Reliable Mechanical Torque sensing system providing safe operation in overload condition.
- Large size window and indicator provides better position indication from a distance.- Various Local position control options providing easy commissioning and operation infield.
- Digitalized control component.
4 I Pratt Industrial
CONSTRUCTION
Cable entries- Standard 2-PF3/4"(Max 1") for various cable gland.
External mechanicalstopper- Prevents over run of travel angle when limit switch fails.
Removable drive bushing mountingbase
Optional long (Explosion proof)
Tapered interface between cover and lower housing- For easy lifting cover up from lower housing for wiring or maintenance.
- Standard: Short interface for providing easier access to internal component
- Explosion proof : Long interface for keeping the length of flame path
Standard short
Gearing
Self locking
- Provided by double worm gearing to keep position of valve unchanged against reverse torque from valve.
Captive cover bolts- Designed to prevent losing it during maintenance or installation.
* All external bolts are stainless steel forrust prevention.
Housing
Sealing
- By O-ring in all interfaces IP67(standard), and double o-ring for IP68 (option)
Handwheel
- Different sizes depending on actuator torque, and knob on handwheel for easy operation.
Motor
- Specially designed induction motor to generate high starting torque and high efficiency equipped with thermal protector to prevent damage from over heating.
- Insulation class F
- Hard anodized Aluminum casting and external epoxypowder coated against severe industrial environment.
- Precisely machined double worm gear c/w minimumback-lash, low noise, high output torque.
Pratt Industrial I 5
Indicator - Continuous mechanical position indicator and window with dial
Limit switches- Directly engaged with
driving shaft to set accurate position of valve.
- 2 ea for each travel end (open/close).
- Optional Extra Limit Switches (Max 4 ea for each end) : Except for ITQ0100
Torque switches - Protect actuator from damage caused by overload from the driven valve over the whole travel.
- 1 each for open / close
Space Heater- Anti-condensation
Terminal- Spring loaded push type terminal for tight wiring connection under severe vibration.
Manual override- Auto / Manual switchable lever and handwheel engagement for emergency manual operation.
- Drive force automatically resorted by motor start, unless lever padlocked to prevent this occuring.

* Each actuator should be powered through its ownindividual switch or relay contacts to prevent cross
feed between two or more actuators.* In case of 3ph actuator, make sure to place
actuator on the middle of travel angle beforeelectrical operation to avoid "jamming"
