Dual Action and Single Action Type (Spring Return)
Pneumatic Actuators



structural feature and technical characteristics:
 

Structural feature	Dual-piston driven, toothed bar and gear driven, structure is compact, position of assembly is symmetrical, motion is swift, turning of output axis can be changed through simple reversal of piston. Output of angle travel:0°~90°.DA stands for dual action; SR stands for single action; namely type of spring return.
Cylinder body	Extruded aluminum alloy cylinder body. The surface is treated by anticathode oxidation which greatly improves the rigidity and anti-corrosion. The internal surface of cylinder is honed and processed so that the fricition coefficient is low and the service life is long.
Baring	The output axis and the piston have chosen high quality bearing which have good stability and sealing, low friction coefficient, large range of applicable temperature and long service lift.
"O"Seal ring	Common type: nitrile butadiene oil resistant rubber. Fluoroelastomer and silicon rubber are used in applicable situation of high and low temperature. Use relevant lubricant.
Regulation of stroke	There are two individual travel set screws on the front face of the cylinder body, the travle can be adjusted ±5°exactly between 0° and 90° location which keeps in line with the open and close position of the valve.
Multi funcational indicator	Inside there are 4×4 standard groove and M6 internal screwed hole which can be smartly mounted with accessories and all-purpose sensor. Embedment of different colors makes visual feeling clear. Embedment of stainless steel is used to install accessible sensor.
Output axis	There are inner octagonal hole at the lower end which accord with ISO05211/DIN3337 and can be expediently carried out interchange of parallel square and diagonally square. Key connections which appointed by users can be available.
Air port	Accord with VDI/VDE3845NAMUR, criterion which can be simply and easily mounted with solenoid valve.
Design of single return	The operation organ of single and dual action have the same cylinder bodies and end shields. It is assembled type pre-load spring qroupware. By increasing or removing spring and realizing scene conversion.
Mounting hole	Top mounting hole accords with VDI/VDE3845 which can mounted with locator limit switch box. Bottom mounting hole accords with ISO05211/DIN3337 which can easily mounted with valve, manual organ or bracket.

Operation principle and rotation direction:
                                               
when pressure of air supply enters from port 2and forces pistons to detach and move toward direction of end shields, air exhausts from port 4,thus anti-clockwise turning is made.when pressure of air supply enters from port 4 and force pistons to fold,the air exhausts from port 2,thus clockwise turning is made.
                                            
when pressure of air supply enters from port 2and forces pistons to detach and move toward direction of end shields, while compresses the spring, air exhausts from port 4,thus anti-clockwise turning is made.
when it is out of or power failure, the spring pushes piston folding and air exhausts from 2,then clockwise turning is made. According to requirements, AIRTORQUE carries out special for swift operation organ and it's the service lift is related yo ordinary operation time.

Dual Action:

 

Port B is fed with air, port A losses air,Pushes. two-piston separated and moved to both ends while the output axis turns anti-clockwise.

   Port A is fed with air and port B losses air,Pushing two pistons folded and moved to the center point while the output axis turns clockwise.

Selection of pneumatic operation organ:
Dual action; Under normal operating condition. recommended reliable coefficient of dual action operation organ is 15-20%
For example; torque of valve=50N.m
             Reliable coefficient (20%)
             Torque of operation organ =50×1.2=60N.m
             Pressure of air supply =0.5Mpa
             Refer to list, under pressure of 5bar, dual action operation
             organ at least generates DA85 by 60N.m.

Single action :
There are two kinds of output torque ;
First, it is gained by compressing the spring resulting from compressing air. In such condition ,force created by pressure of air supply forcing pistons subtracts created by compressed spring, and output torque descends gradually from max. of jumping-off till 90°which is minimum.
Second, it is gained by resting force of spring when air exhausts. In such condition, because of gradual elongation of spring, output torque descends from max. of 90°to minimum of 0°.
For example; valve moment =80N.m
             Confidence coefficient (20%)
             Pressure of air supply =4bar
             Torque of operation organ =80×1.2=60N.m
             Refer to list, the selected single action operation organ is SR140 s3
             while under air source pressure, minimum torque is 117.75N.m
             when the spring resets, minimum torque is 111.44N.m
when  butterfly valve is closed, the torque turned on is large, single action operation organ can be economically selected through skillful use of opening and closing of air exhaustion.
