Key to diagram:
630 Wrapping table flow control valve
706 Pressure relief valve
769 Film clamping cutters flow divider
Description of function:
The valve combination (7) combines the components (630, 706 and 769).
Wrapping table flow control
valve (630)
The wrapping table flow control valve supplies the hydraulic motor (235).
This volume flow can be adjusted to up to 8 l/min. and changes the
wrapping table motor / wrapping arm motor speed ratio and consequently
the film layer overlaps.
- low speed = large film overlap;
- high speed = small film overlap
Pressure relief valve (706) The pressure relief valve limits the pressure to 70 bar when lowering the
tipping cradle hydraulic cylinders (375).
Film clamping cutters flow
divider (769)
The flow divider divides the oil flows for opening and closing the film
clamping cutters.
