Operating Principle
Spring Return (R-closed, fail closed)
Installation of Springs for Spring Return Actuator
By supplying air to Port A, pressure is applied to thecenter chamber and forces the dual pistons outward.Linear piston force is transferred via gear racks to the pinion gear, causing the pinion to turn counterclockwise while the air is being exhausted from Port B.
By supplying air to Port B, pressure is applied to theoutside chamber and drives the dual pistons inward.The action causes the pinion to turn clockwise whilethe air is being exhausted from Port A.
By supplying air to Port A, pressure is applied to thecenter chamber, forcing the dual pistons outward, compressing the springs in the outside chambers to produce a counterclockwise rotation. Exhaust air exits at Port B.
Upon loss of air pressure, the stored energy in thecompressed springs forces the pistons inwards producing rotary motion with exhaust air exiting at Port A. This "fail safe" position is held by spring force until air pressure reapplied to Port A.
Stroke Adjustment:Stroke Adjustment: Pinion stops allow ±5°adjustment at 0°and 90°.

Indicator - Position indicator with NAMUR is
convenient for mounting accessories such as limit
switch box, positioner and so on.
Pinion -Fully conform to the latest standards of
ISO5211,DIN3337,NAMUR.The dimensions can be
customized and the stainless steel is available.
Actuator body - The extruded aluminum alloy
ASTM6005 body can be treated with hard
anodized, powder polyester painted (different
colors is available such as blue, orange, yellow etc).
End caps - Die-casting aluminum powder
polyester painted in different colors.
Pistons - The twin rack pistons are made from
die-casting aluminum treated with hard anodized.
Travel adjustment - The two independent external
travel stop bolts allow ±5°adjustment at the
positions of 0°and 90°.
High performance springs - Preloaded coating
springs are made from the high quality material for
longer cycle life and resistant to corrosion.
Bearings & guides - Made from low friction, long-
life compound material, to avoid the direct contact
between metals. The maintenance and
replacement are easy and convenient.
