ACCESS
Automation - Communication - Control and Evaluation of System Status

Worcester's Answer to your Actuation and Indication Need.
ACCESS - Your Single Source Interface.

It's Time to Change the Traditional Method of On-Off Control. 

Why buy an actuator and add accessories to it?

That was our customer's question. The answer is a newly designed actuator that offers all the necessary control, communication, and annunciation of system status as an integral part of the actuator. The unique, guide rod design of Worcester's Series 39 actuator makes this possible. 
Guide rods are the supporting framework for the pistons of the Series 39 actuator. They prevent the pistons from misaligning and coming in contact with the actuator cylinder creating piston seal wear. Guide rods also prevent piston seals from uneven compression and additional wear. Each time the actuator cycles, the pistons and guide rods move. ACCESS adds to the advantages offered by the guide rod design by utilizing their movement to detect valve position. 

 

Incorporating limit switches and a solenoid as an integral part of the actuator proves to be an advantage because it eliminates the need for brackets, shaft couplings, nipples, and additional enclosures. All this functionality is available in one compact enclosure. 

The Choice for On-Off Control
  • Double-acting or fail-safe.
  • Single housing for both pneumatic and electrical interface.
  • LED indicating lights assist in calibration and troubleshooting
  • Eliminates need for brackets, couplings, nipples, shafts, or additional enclosures
  • Improved interface with existing systems
  • Standard enclosure available conforming to Type 4, $X, 7, 9 and 12 ratings
  • Top shaft free for manual override and mechanical position indication
  • High flow spool valve to satisfy quick cycling applications
  • Increased reliability and reduced downtime
  • Lower power consumption and more efficient coils add up to decreased operating cost
  • Intrinsically safe design available optionally
  • Single source responsibility
  • Suitable for corrosive environments
  • Choice of limit switches
Available Options
  • Clear Lexan® cover rated to type 4, 4x.
  • Solid aluminum cover rated to type 4, $x, 7, 9, 12.
  • 12 or 24v DC or 24, 120, 240v AC solenoid.
  • LED's available in all models for most voltages.
  • With or without solenoid or high flow spool valve.
  • SPDT switches.
  • AC/DC proximity switches on mounted unit variation.
  • Manual override and two independently adjustable speed controls offered with spool valves.
