2 Double Acting (R-closed) Operating Principle A B A B By supplying air to Port B, pressure is applied to the outside chamber and drives the dual pistons inward. The action causes the pinion to turn clockwise while the air is being exhausted from Port A. By supplying air to Port A, pressure is applied to the center 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. Spring Return (R-closed, fail closed) A B A B Upon loss of air pressure, the stored energy in the compressed 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. By supplying air to Port A, pressure is applied to the center chamber, forcing the dual pistons outward, compressing the springs in the outside chambers to produce a counterclockwise rotation. Exhaust air exits at Port B. Stroke Adjustment: Stroke Adjustment: Pinion stops allow ± adjustment at 0 and 0.

3 Materials and Structure 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 ISO,DIN333,NAMUR.The dimensions can be customized and the stainless steel is available. 3 Actuator body - The extruded aluminum alloy ASTM00 body can be treated with hard anodized, powder polyester painted (different colors is available such as blue, orange, yellow etc) 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 ± adjustment at the positions of 0 and 0. 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, longlife compound material, to avoid the direct contact between metals. The maintenance and Insert (Optional) O-rings NBR rubber o-rings provide trouble-free operation at standard temperature ranges. For high and low temperature, viton or silicone is used. replacement are easy and convenient. No. Part Description Qty. Material No. Description Qty.

12 Operating Conditions Remove any manual opening device from the valve, leaving the valve stem clear. Make sure that the shape of the stem fit the actuator output and that the rotation is not hindered in any way. Mount the actuator onto the valve, certaining it well on the stem. Make sure that the rotation direction is correct, in any case do not insert your hands inside the valve. We strongly suggest checking the cleanness of the air-supply pipes, especially when the plant is not provided with filters. A spacer between actuator and valve will be necessary with fluids at high temperature. Maintenance.It is recommended that periodic checks be performed to make sure that all fasteners remain tight..the actuator is supplied ready-lubricated no further lubrication is required. If lubrication is deemed necessary, use EP- grease. 3.Under certain working conditions (heavy duty, non-compatible operating media or abnormal operating conditions)internal seals should be checked periodically and replaced when necessary. 4.On spring return actuators, spring fatigue may set in requiring the replacement of springs. Spring should always be replaced in full sets. NOTE If an actuator is properly assembled and used, it will be maintenance free, as it has been lubricated enough to last a normal working life under normal working conditions. Should it get necessary to replace its seals, we suggest turning to our company where the product will be overhauled first, and then tested. On request, our company will be willing to provide its customers with kits and instructions. oup.com
