Installation
5.3 Adjustment „Bypass-Valve"
The retrofitting of a so-called „bypass valve" on the hydraulic rotator is necessary to pass one part of oil to the return flow
of the support device, when the volume flow rate is above 40 l/min.
The optimal adjustment has to be made during actual operation of the installation clamp.
WARNING:
If the shifting force of the side grippers is too low, the bypass valve most likely is opened too far! In this case
the bypass valve has to be tighten up slightly (so the volume flow rate of the oil to the installation clamp is
reduced).
For support devices with volume flow rate ≤ 40 l/min the bypass valve remain completely closed!
