PVG 48 is an addition to the pre-compensated PVG family.
The PVG 48 program is intended to deliver the highest possible flow and lowest possible pressure drop,
using the same interface as PVB 32.
PVB 48 is a compensated module that is intended for controlling a work function behavior in terms of
flow and pressure, independent of the load pressure of the functions used simultaneously.
The PVB 32 interface allows the integration of the PVB 48 in the PVG 32/16 valve stacks without additional
adapters.
Spool stroke is ±7 mm in the PVB 48 module like in the PVB 32, this allows the use the common modules,
such as PVM housing, PVE actuators, shock valve with anti-cavitation valve (PVLP), anti-cavitation valve
(PVLA) or LS A/B relief valves.
Additional anti-cavitation valve in A port is available in select PVB variants, for improved anti-cavitation
capability.

The PVLP shock and anti-cavitation valve will relieve a pressure peak to the internal tank galleries and will
furthermore suck oil from the tank to the work port to prevent cavitation. Pressure settings range: 32–400
bar [460–5800 psi].
The pressure setting of the PVLP must always be 20 bar [290 psi] higher than LS
A/B
setting in the same
module.

The PVLA valve is an accessory available for PVB basic modules.
The PVLA will suck fluid from the tank to the work port to prevent cavitation by the 0.5 bar spring. The
plug will ensure that when using a single acting spool, all flow returning through the work port is led to
tank.

The main spool (PVBS 48) determines the flow or pressure out of the work section.
The PVBS 48 main spool variant is based on PVBS 32 spool platform and therefore have a wide selection
of additional features, which enables you to tailor the PVG to suit the function in the application for a
hydraulic system. PVBS 48 supports higher flow range.
The PVBS 48 main spool can be activated in three different ways:
•
Mechanically by a PVM lever.
•
Electrically by a PVE/PVHC actuator
•
Hydraulically by a PVH actuator

The closed center PVPM 48 mid-inlet module act as a simple manifold and is intended for use with
variable displacement pump (Closed Center). The PVPM features two PVLP shock/anti-cavitation valve
facilities for pressure peak protection and anti-cavitation protection.
PVPM must be combined with PVP/PVPV 32 closed center inlet or start plate with pilot reduction valve
and LS port, to supply pilot pressure for the actuators and send signal to the variable pump. For start
plate, see PVG 32 start plate section.
The PVPM closed center inlet features:
•
Two integrated shock/anti-cavitation valve facilities (PVLP)
•
Threaded ports for P/T
•
Pilot pressure compatible
•
T0 compatible

The PVSI 48 end plate is placed at the end of the valve stack section. PVSI 48 have additional P- and T-port
enabling additional pump flow to PVG 48 valve. The PVSI 48 feature a PVLP shock/anti cavitation valve
facility for pressure peak/anti-cavitation protection. The unique design of the PVSI ensures very low
internal pressure drop in the PVG. Due to the placement of the tank port, increased tank pressure may be
expected.
The end plate is ensuring Load Sense (LS) pressure is relieved to tank when the valve is not operated.
The PVSI 48 with P-, T-, M connection features:
•
Threaded P/T/M port
•
Integrated shock valve facility
