MATERIALS OF CONSTRUCTION
BODY: Aluminium with Teflon® Imprenated Hard Anodized (PolyLube®) Sufaces
EXTERNAL HARDWARE: (Pinion Shaft, Driver, End Caps) 300 Series Stainless Steel
SPRING MODULES: A512SR Zytel ® Housing, A522SR Aluminium with Teflon® Imprenated
Hard Anodized (PolyLube®) Sufaces, 300 Stainless Hardware
EXTERNAL TRIM: 300 Series Stainless Steel
RATINGS / SPECIFICATIONS
TEMPERATURE: -20 F to 350 F
POWER: 50 - 125 psi air. Sufficient air delivery must be available at the actuator to ensure depend-
able operation. The following precautions should be observed: Air supply should be clean and free of
moisture. When dirty or wet air is a problem; a filter / separator should be specified; these units are
most effective when installed as closely as possible to the actuator. A filter, when used, should permit
a minimum flow of 4 scfm at an upstream pressure of 60 psi. Eliminate severe restrictions to air flow
(certain solenoid valves & fittings). The most restricted passage must have an area no smaller than
.012 inches square, the area of 1/8" diameter orifice. If more than a single actuator is to be supplied
by an individual pilot, the minimum passage requirement applies per actuator.
TUBING: For short runs up to 5 feet 5/32" I.D. is suitable, 1/4" I.D. will serve up to 30 feet. For
longer runs, use 3/8" I.D. or larger.
