The Access System is a totally integrated actuation
package to include actuator, solenoid, limit switches &
monitoring LEDS in as a single unit.
The Access system with
the clear Lexan cover
gives a clear view of the 4
colored LEDS
The Access system with the
Cast Aluminum Impregnated
and Anodized cover for
complete NEMA ratings.
| The Access System is built around the rugged construction of Worcester Series 39 Pneumatic
Actuator. Stainless Steel Guide Rods make the series 39 actuator unique. It is the only double piston
rack and pinion actuator designed with piston guide rods. |
Valve position can be monitored via
limit switches or visually through the
optionally available Lexan end
cover. Leds assist during valve
setup, calibration & trouble
shooting.
Coil continuity and voltage are
verified by the orange & yellow leds.
Open and closed are monitored by
the Green & Red leds.
Limit switches are easily adjusted
with the assistance of the leds.
