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.
DESCRIPTION
500 Series
pneumatic actuators are the latest in compact rack
and pinion valve automation from Gemini Valve. The A500 fea-
tures 50 psi operation on all models and sizes and includes
many industry standards features such as NAMUR interfaces
and ISO mounting options.
