Pneumatic Actuator

MODEL NO: AND(S)AFL
Pneumatic Actuators PRODUCT'S SIZE:
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,
