38
V4
Check valve
(VRC 6.)
This prevents oil from flowing to the circulation valve in closed centre hydraulics.
V5
Regulator for V6
(CP 610-2.)
Used to adjust the volume of oil that flows into the volume-control valve, which in turn regulates the
amount of oil that flows into the control block.
At the factory this is set to 35 litres/minute.
This must not be adjusted to a higher figure.
V6
Volume-control valve
(CP 311-4.)
Limits the volume of oil that flows into the control block. Excess oil volume is sent back to the
tractor. This is designed to handle an oil volume of up to 60 litres/minute.
V7
Emergency overflow valve
(CP 200-3.)
Safety valve on the return side. If the return hose should become blocked, this will open and release
oil into the outside. The purpose of this valve is to stop the pressure becoming too high in the
drainage connection on the wrapping arm motor. This is set to 120 bars.
V8
Safety valve
(CP 200-3.)
This prevents the oil pressure from becoming too high in the control block. If the preset pressure
level is exceeded, this valve opens and the oil is sent to the return hose. It is set at 180 bars.
