1) Could you tell me the pneumatic cylinder pneumatic actuator
Double acting working principle:
Air to Port 2 forces the pistons outwards, causing the output shaft
to turn counterclockwise while
the air is being exhausted from Port 4. (Clockwise) Air to Port 4
forces the pistons inwards, causing
the pinion to turn clockwise while the air is being exhausted from
Single acting working principle:
Air to Port 2 forces the pistons outwards, causing the springs to
compress, the pinion turns counterclockwise
while air is being exhausted from Port 4. (Clockwise) Loss of air
pressure, the stored energy in the springs forces
the pistons inwards, the pinion turns clockwise while air is being
exhausted from port 4.
2) How is the air supply?
----> Supply clean dry air, also can be installation an air
filter pressure relief valve of the pneuamtic actuator and
Pneumatic valve. it mainly need 3-8bar air supply can be open the
actuator and the valve rotary operation.
3) Can it direct mount limit switch box?
----> The side connection conforms to the VDI/VDE 3845 NAMUR standard can
be installed the solenoid valve directly.
The top connection conforms to VDI/VDE 3845 NAMUR standard and the
limit switch box or positioner can be directly
