21. Hydraulic pressure regulator
Enables the pressure of the hydraulic circuit to be increased or
reduced.
With VK Pump.-
To increase pressure, turn the tap clockwise;
to reduce pressure, turn the tap anti-clockwise.
With BR Pump.-
The pressure is set with the pressure setting screw (position D).
Undo the lock nut with a short length screwdriver to set the pressure range by turning the
pressure screw with hexagon socket 4 mm. Turning the setting screw clockwise increases the
flow. Turning the setting screw counter clockwise decreases the flow. One turn of the setting
screw corresponds to 50 bar pressure.
When the setting screw cannot be turned clockwise or counter clockwise easily, is because the
lock nut is jammed up against the setting screw. In this case, turn clockwise the setting screw to
unlock the lock nut.
The flow regulation (standby pressure) setting screw (position F) should not require adjustment
In both cases the NORMAL or RETRACT commands must be active before you can adjust the
pressure of the hydraulic circuit.
The hydraulic circuit should be regulated to ensure that the
unit’s output pressure never exceeds the working pressure of
the product hoses fitted to the unit.
