PVG is a hydraulic, load-sensing proportional valve, designed for optimal machine performance and
maximum design flexibility.
The PVG valve design is based on a modular concept that enables machine designers to specify a valve
solution suitable for multiple market segments across multiple applications.
The load independent proportional control valve and high performance actuator technology combined
with a low pressure drop design improves the machine performance and efficiency – increasing
productivity and reducing energy consumption.
Features of PVG 32

Open center PVP
Description of the example: PVG 32 with open center PVP (fixed displacement pump) and PVB with flow
control spool.
When the pump is started and the main spools in the individual basic modules (11) are in the neutral
position, oil flows from the pump, through connection P, across the pressure adjustment spool (6) to
tank. The oil flow led across the pressure adjustment spool determines the pump pressure (stand-by
pressure).
When one or more of the main spools are actuated, the highest load pressure is fed through the shuttle
valve circuit (10) to the spring chamber behind the pressure adjustment spool (6), and completely or
partially closes the connection to tank to maintain pump pressure. Pump pressure is applied to the right-
hand side of the pressure adjustment spool.
The pressure relief valve (1) will open when the load pressure exceed the set value, diverting pump flow
back to tank.
In a pressure-compensated basic module the compensator (14) maintains a constant pressure drop
across the main spool – both when the load changes and when a module with a higher load pressure is
actuated.
With a non pressure-compensated basic module incorporating a load drop check valve (18) in channel P,
the check valve prevents return oil flow.
The basic module can be supplied without the load drop check valve in channel P for functions with over-
center valves.
The shock valves PVLP (13) with fixed setting and the suction valves PVLA (17) on ports A and B are used
for the protection of the individual working function against overload and/or cavitation.
An adjustable LS pressure limiting valve (12) can be built into the A and B ports of pressure-compensated
basic modules to limit the pressure from the individual working functions. The LS pressure limiting valves
save energy compared with:
•PVLP all the oil flow to the working function will be led across the combined shock and suction valves
to tank if the pressure exceeds the fixed setting.
•LS pressure limiting valves an oil flow of about 2 l/min [0.5 US gal/min] will be led across the LS
pressure limiting valve to tank if the pressure exceeds the valve setting.
Please see the sectional drawing Sectional view on page 9 for better understanding of this example.
Closed center PVP
Description of the example: PVG 32 with closed center PVP (variable displacement pump) and PVB with
flow control spool.
In the closed center version of PVP an orifice (5) and a plug (7) have been fitted instead of the plug (4).
This means that the pressure adjustment spool (6) will open to tank when the pressure in channel P
exceeds the set value of the pressure relief valve (1). The pressure relief valve in PVP should be set at a
pressure of approx. 30 bar [435 psi] above maximum system pressure (set on the pump or external
pressure relief valve).
In load sensing systems the load pressure is led to the pump control via the LS connection (8). In the
neutral position the pump load sense control sets the displacement so that leakage in the system is
compensated, to maintain the set stand-by pressure. When a main spool is actuated the pump load sense
control will adjust the displacement so that the set differential pressure (margin) between P and LS is
maintained.
Please see the sectional drawing Sectional view on page 9 for better understanding of this example.

Load sensing for variable displacement pump supply
The pump receives fluid directly from the reservoir through the inlet line. A screen in the inlet line
protects the pump from large contaminants.
The pump outlet feeds directional control valves such as PVG-32, hydraulic integrated circuits (HIC), and
other types of control valves.
The PVG valve directs and controls pump flow to cylinders, motors and other work functions. A heat
exchanger cools the fluid returning from the valve. A filter cleans the fluid before it returns to the
reservoir.
Flow in the circuit determines the speed of the actuators. The position of the PVG valve spool determines
the flow demand. A hydraulic pressure signal (LS signal) communicates demand to the pump control.
The pump control monitors the pressure differential between pump outlet and the LS signal, and
regulates servo pressure to control the swashplate angle. Swashplate angle determines pump flow.
Actuator load determines system pressure. The pump control monitors system pressure and will decrease
the swashplate angle to reduce flow if system pressure reaches the pump control setting.
A secondary system relief valve in the PVG valve acts as a back-up to control system pressure.

All types of control valves (incl. proportional valves) can fail, thus the necessary protection against the
serious consequences of function failure should always be built into the system. For each application an
assessment should be made for the consequences of pressure failure and uncontrolled or blocked
movements. To determine the degree of protection that is required to be built into the application,
system tools such an FMEA (Failure Mode and Effect Analysis) and Hazard and Risk Analysis can be used.
FMEA – IEC EN 61508
FMEA (Failure Mode and Effect Analysis) is a tool used for analyzing potential risks. This analytical
technique is utilized to define, identify, and prioritize the elimination or reduction of known and/or
potential failures from a given system before it is released for production. Please refer to the standard IEC
FMEA 61508.
Hazard and risk analysis ISO 12100-1/14121
This analysis is a tool used in new applications as it will indicate whether there are special safety
considerations to be met according to the machine directives EN 13849. Dependent on the determined
levels conformity this analysis will detirmine if any extra requirements for the product design,
development process, production process or maintenance, example the complete product life cycle.
W
Warning
All brands and all types of directional control or proportional valves, which are used in many different
operation conditions and applications, can fail and cause serious damage.
Analyze all aspects of the application. The machine builder/system integrator alone is responsible for
making the final selection of the products and assuring that all performance, safety and warning
requirements of the application are met. The process of choosing the control system and safety levels is
governed by the machine directives EN 13849 (Safety related requirements for control systems).

There is a wide range of pressure settings and fluid flow controls.
Load sensing controls
The LS control matches system requirements for both pressure and flow in the circuit regardless of the
working pressure. Used with a closed center control valve, the pump remains in low-pressure standby
mode with zero flow until the valve is opened. The LS setting determines standby pressure.

Load sensing circuit
P101 967
Most load sensing systems use parallel, closed center, control valves with special porting that allows the
highest work function pressure (LS signal) to feed back to the LS control.
Margin pressure is the difference between system pressure and the LS signal pressure. The LS control
monitors margin pressure to read system demand. A drop in margin pressure means the system needs
more flow. A rise in margin pressure tells the LS control to decrease flow.
LS control with bleed orifice (do not use with PVG valves)
The load sense signal line requires a bleed orifice to prevent high-pressure lockup of the pump control.
Most load-sensing control valves include this orifice. An optional internal bleed orifice is available, for use
with control valves that do not internally bleed the LS signal to tank.
Integral PC function
The LS control also performs as a PC control, decreasing pump flow when system pressure reaches the PC
setting. The pressure compensating function has priority over the load sensing function.
For additional system protection, install a relief valve in the pump outlet line.
Load sensing system characteristics:
•Variable pressure and flow
•Low pressure standby mode when flow is not needed
•System flow adjusted to meet system requirements
•Lower torque requirements during engine start-up
•Single pump can supply flow and regulate pressure for multiple circuits
•Quick response to system flow and pressure requirements

P101 966
The remote PC control uses a pilot line connected to an external hydraulic valve. The external valve
changes pressure in the pilot line, causing the PC control to operate at a lower pressure. When the pilot
line is vented to reservoir, the pump maintains pressure at the load sense setting.
When pilot flow is blocked, the pump maintains pressure at the PC setting. An on-off solenoid valve can
be used in the pilot line to create a low-pressure standby mode. A proportional solenoid valve, coupled
with a microprocessor control, can produce an infinite range of operating pressures between the low
pressure standby setting and the PC setting.
Size the external valve and plumbing for a pilot flow of 3.8 l/min [1 US gal/min]. For additional system
protection, install a relief valve in the pump outlet line.
Remote pressure compensated system characteristics:
•Constant pressure and variable flow
•High or low pressure standby mode when flow is not needed
•System flow adjusts to meet system requirements
•Single pump can provide flow to multiple work functions
•Quick response to system flow and pressure requirements
Typical applications for remote pressure compensated systems:
•Modulating fan drives
•Anti-stall control with engine speed feedback
•Front wheel assist
•Road rollers
•Combine harvesters
•Wood chippers
PVPC with check valve for open center PVP
PVPC with check valve is used in systems where it is necessary to operate the PVG 32 valve by means of
the electrical remote control without pump flow. When the external solenoid valve is opened, oil from
the pressure side of the cylinder is fed via the PVPC through the pressure reducing valve to act as the

pilot supply for the electrical actuators. This means that a load can be lowered by means of the remote
control lever without starting the pump.
The built-in check valve prevents the oil from flowing via the pressure adjustment spool to tank. With the
pump functioning normally the external solenoid valve is closed to ensure that the load is not lowered
due to the pilot supply oil flow requirement of approximately 1 l/min [0.25 US gal/min]. With closed
center PVP the external pilot oil supply can be connected to the pressure gauge connection without the
use of a PVPC plug.

PVPC without check valve for open or closed center PVP
PVPC without check valve is used in systems where it is necessary to supply the PVG 32 valve with oil
from a manually operated emergency pump without directing oil flow to the pilot oil supply (oil
consumption about 0.5 l/min) [0.13 US gal/min].
When the main pump is working normally, the oil is directed through the PVPC plug via the pressure
reduction valve to the electrical actuators.

When the main pump flow fails, the external shuttle valve ensures that the oil flow from the manually
operated emergency pump is used to pilot open the over center valve and lower the load. The load can
only be lowered using the mechanical operating lever of the PVG 32 valve.
PVMR, friction detent
The friction detent PVMR allows the directional spool to be held in any position, resulting in infinitely
variable, reversible, pressure compensated flow.
This can be sustained indefinitely without having to continue to hold the mechanical lever. Friction
detent spool position may be affected by high differential actuator flow forces and system vibration
resulting in work function flow reduction.

PVMF, mechanical float position lock
Allows the float spool to be held in the float position after release of the mechanical handle.
PVMF, standard mount only
P →A →F (Push-in)
PVMF, optional mount only
P →A →F (Pull-out)
PVBS, main spools for flow control (standard)
When using standard flow control spools, the pump pressure is determined by the highest load pressure.
This is done either via the pressure adjustment spool in open center PVP (fixed displacement pumps) or
via the pump control (variable displacement pumps).
In this way the pump pressure will always correspond to the load pressure plus the stand-by pressure of
the pressure adjustment spool or the pump control. This will normally give optimum and stable
adjustment of the oil flow.
