Data Sheet

Module

PVP OC/CC

The PVG 32 inlet program now offers an inlet module
with selectable Open Center/Closed Center
configuration in same module.

The module directs itself to application with a PVG
valve fitted but where the pump type is not
determined by the machine builder. A typical
application could be an agricultural attachment.

The pump type will be determined by the tractor
pulling the attachment and the valve inlet can easily
be changed to fit the pump.

For systems with LS leak/bleed-off and long LS lines
the module is also available with an unique
integrated LS boost functionality to ensure fast and
prompt reaction.

Features

•

Maximum system pressure relief setting

•

Integrated pressure matching spool

•

Integrated pilot oil pressure supply for
PVE

•

Possibility to switch from Open Center
to Closed Center or vice versa externally
on application using hex key

•

Possibility for integrated LS boost to
compensate for LS bleed-off and
leakage

OC/CC selector

Changed using a 6 mm hexagonal key.

Turned clockwise (screw in) equals Open Center configuration.
The oil then flows from the pump through the P-port in the PVP
OC/CC module across the main spool to tank. The oil led across
the pressure adjustment spool determines he pump pressure.
When one or more sections in the valve stack is being actuated,
the highest load pressure is fed to the spring chamber behind the
pressure adjustment spool and completely or partially closes the
connection to tank.

Turned counter-clockwise (screw out) equals Closed Center
configuration. The oil still enter though the P-port in the PVP
OC/CC module but the pressure adjustment spool will only open
to tank when the P-channel pressure exceeds the setting of the
pressure relief valve. The LS signal is led to the pump regulator
through the LS-port connection.

LS boost

The LS to the pump regulator can be increased by using an
integrated LS boost. The LS signal comming out of the plug will
then be 6 bar higher than the actual LS pressure in the valve stack.
