d series pneumatic actuators

Our newly-designed D Series Pneumatic Actuator is aluminum rack & pinion actuators in double acting and spring return based on ourinnovative and patented technology. This kind of actuator features a top mount multifunction indicator and open-close stop adjustment as a standard. In addition, state-of-the-art engineering has allowed us toreduce the size of the actuator without losing any torque. The featuresand characteristics of the actuator have kept pace with 4th generationpneumatic actuator in the world.

Design

8. Bearings & guidesMade from low friction, long-life compoundmaterial, to avoid the direct contactbetween metals. The maintenance andreplacement are easy and convenient.

9. O-ringsNBR rubber o-rings provide trouble-freeoperation at standard temperature ranges.For high and low temperature, viton orsilicone is used.

Operating Principle

Double acting

Spring return

Standard Rotation:Air to port A forces the pistons outwards, causing the pinion to turn counterclockwise whilethe air is being exhausted from port B. Air to port B forces the pistons inwards, causing thepinion to turn clockwise while the air is being exhausted from port A.

Reverse Rotation:Air to port A forces the pistons outwards, causing the pinion to turn clockwise while the air isbeing exhausted from port B. Air to port B forces the pistons inwards, causing the pinion toturn counterclockwise while the air is being exhausted from port A.

Standard Rotation

Reverse Rotation:

:Air to port A forces the pistons outwards, causing the springs to compress, the pinion turnscounterclockwise while air is being exhausted from port B. Loss of air pressure on port A, thestored energy in the springs forces the pistons inwards. The pinion turns clockwise while airis being exhausted from port A.

Manual Operat ion

Remove any manual opening device from the valve, leaving the valve stem clear. Make surethat the shape of the stem fit the actuator output and that the rotation is not hindered in anyway. Mount the actuator onto the valve, certaining it well on the stem. Make sure that therotation direction is correct, in any case do not insert your hands inside the valve. We stronglysuggest checking the cleanness of the air-supply pipes, especially when the plant is notprovided with filters. A spacer between actuator and valve will be necessary with fluids at hightemperature.

Spr ings mount ing form for spr ing return actuators :

Maintenance1.It is recommended that periodic checks be performed to make sure that all fastenersremain tight.2.The actuator is supplied ready-lubricated no further lubrication is required. If lubrication isdeemed necessary , use EP-1 grease.3.Under certain working conditions (heavy duty, non-compatible operating media orabnormal operating conditions)internal seals should be checked periodically and replacedwhen necessary.4.On spring return actuators, spring fatigue may set in requiring the replacement of springs.Spring should always be replaced in full sets.

NOTEIf an actuator is properly assembled and used , it will be maintenance free, as it has beenlubricated enough to last a normal working life under normal working conditions. Should itget necessary to replace its seals, we suggest turning to our company where the product willbe overhauled first, and then tested. On request, our company will be willing to provide itscustomers with kits and instructions.
