This is a full fledged servo-system using pneumatic pressure as energy source. When palm is deflected by the edge of wire/ felt servo valve sends variable
pneumatic pressure to the actuator which in turn swings the pendulum forward/ Reverse as the case may be. Servo valve controls both pressure and flow rate of compressed air proportional to magnitude and direction of signal generated by the palm. Servo system is provided with R.C. net work as well as Viscons damping device to ensure high frequency Response and adequate stability under all operating conditions.

Air Supply
Appropriate FRL unit of reputed make is to be used and ensure that supply Pressure is maintained at 5 to 6 bars under all conditions.
Mounting
Use lifting eye bolt for handling. Our standard design is such that it can easily be mounted in the “ T Slots” of the paper-machine-base.
Lubrication Grease lubricants once a year at the nipple provided.

Spare Parts
Under normal circumstances this equipment will not need any
spares for 5- 10 years of operation. In the event of any accidental
damages please indicate the model No. and S.No. to enable us to send
you replacement parts.
After some 15 years or so it may need some rebuilding, replacing worn out
pins, replacing servo valve etc. We under take to rebuild the unit, at that
time, at nominal costs. Tubes and fillings used are of international
standard- 1/8 inch BSP and you may replace them if any damage takes
place during the course of its life. Do not change dia or length of piping, as
it will interfere with original calibration.
Spare Palm Rods are supplied with AGP-200.
Guarantee
This equipment is guaranteed for a period of five years and defective
parts, if any, will be replaced free of cost. Guarantee will be null and void
if the servo-valve is dismantled and opened. It is calibrated unit and so it
will get “ totally- lost” once dismantled.
Settings of R.C.Circuit and dampener should also not be disturbed.

Low initial cost |
 |
Low running cost needs no maintenance - fit & forget |
 |
Based on " Beloit - USA " design. |
 |
Very low air consumption. |
 |
No sliding parts consequently no wear , no lubrication required .Roll reaction taken by sealed ball bearing , lubricated for life and operates at Zero speed , sensitive servo valve needs low contact pressure with web and provides fast response. |
 |
Actuator has no wearing parts , moving seals , no friction and hence long maintenance free life |
 |
Guaranteed for life. |
