Technical Information
PVG 48
PVG 48
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 offlow 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 additionaladapters.
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.

Technical Information
PVG 48PVLP Shock and Anti-Cavitation Valve
The PVLP shock and anti-cavitation valve will relieve a pressure peak to the internal tank galleries and willfurthermore suck oil from the tank to the work port to prevent cavitation. Pressure settings range: 32–400bar [460–5800 psi].
The pressure setting of the PVLP must always be 20 bar [290 psi] higher than LSA/B setting in the samemodule.

Technical Information
PVG 48PVLA Suction Valve
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. Theplug will ensure that when using a single acting spool, all flow returning through the work port is led totank.

PVBS for PVB 48
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 selectionof additional features, which enables you to tailor the PVG to suit the function in the application for ahydraulic 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

PVG 48PVPM 48
The closed center PVPM 48 mid-inlet module act as a simple manifold and is intended for use withvariable 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 startplate, see PVG 32 start plate section.

PVG 48PVSI 48
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 lowinternal pressure drop in the PVG. Due to the placement of the tank port, increased tank pressure may beexpected.
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
