Fig. 14-6
14.8
The valve block on fig. 14-6 has three valves:
a)
Pressure limit valve, (S5), which protects the left roller motor against too large difference
of pressure between oil inlet and outlet.
b)
Magnet valve, (44), which is activated when rollers out are operated.
c)
Non-return valve which prevents oil from flowing to the wrapping arm motor when rollers
width is operated.
When rollers out are operated, the oil flows from the minus-side of the width-cylinder and through
the left roller motor before it flows back to the valve block. When rollers in are operated the oil flows
the opposite way.
To be able to operate rollers out at all, valve no. 44 must have electric power at the same time as
valve no. 4.
