PVG general description
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 the PVG 128/256 valve
Inlet flow up to 1200 l/min [317 US gal/min]
Compact sectional platform solution for easy integration with PVG 16 and PVG 32
Load-independent flow control:
Oil flow to an individual function is independent of the load pressure of this function
Oil flow to one function is independent of the load pressure of other functions
Reliable regulation characteristics across the entire flow range
Load sense relief valves for A and B port enables reduced energy loss at target pressure
Optimized for lower pressure drop and higher efficiency
Several options for connection threads and flange mount
Compact design, easy installation and serviceability
Static Load sense system when selecting pump control

The Closed Center PVPV inlet with integrated pilot pressure reduction valve (PPRV) for PVE activation is
intended for use with variable displacement pumps in applications where a valve group with electro-
hydraulic or hydraulically controlled work sections is desired.
All Variants are prepared for 2xPVLP shock/anti-cavitation valves for pressure peak protection and anti-
cavitation prevention.
PVLPs are for pressure peak protection in the system and pump.
Optional electrically actuated pilot shut off valve PVPP provides additional functional system safety by
removing pilot oil from the electrical actuation or hydraulic actuation system, disabling main spool
actuation.
All variants have internal T0 to tank connection in the PVSI and PVGI end plates.

PVB 128 3-way Compensator with LS A/B and PVLP
The compensated PVB is intended for controlling a work function where the function behavior in terms
of flow and pressures requires independency on the load pressure of other functions used
simultaneously.
The integrated LS A/B relief valves are used to limit the maximum work port pressure on the A and B-
ports individually.
Featuring 2xPVLP shock/anti-cavitation valves on each work port for pressure peak protection and anti-
cavitation prevention
The compensator is a 3-way type which include load drop check valve functionality, compensator
function and neutral relief which avoid A and B port pressure build up in neutral.

The PVG 256 Basic modules (PVB), also referred to as work sections, is the interface between the PVG 256
proportional valve group and the work function such as a cylinder or a motor.
The PVB basic module variants are based on a generic platform with a selection of additional features,
enabling you to tailor the PVB to suit the demands of any hydraulic system.
The compensator is a 3-way type which includes load drop check valve functionality, compensator
function and neutral relief which avoid A and B port pressure build up.
The generic PVB basic module platform includes the following main variants.

PVB 256 3-way Compensator with LS A/B
The compensated PVB is intended for controlling a work function where the function behavior in terms
of flow and pressures requires independency on the load pressure of other functions used
simultaneously.
The integrated LS A/B relief valves are used to limit the maximum work port pressure on the A and B-
ports individually.
The compensator is a 3-way type which include load drop check valve functionality, compensator
function and neutral relief which avoid A and B port pressure build up in neutral.

PVLP is set at an oil flow of 10 l/min [2.6 US gal/min] per unit.
The shock valve PVLP is designed to absorb shock effects. Consequently, it should not be used as a
pressure relief valve.
If the working function requires the use of a pressure relief valve, a PVB basic module with built-in LSA/B
pressure limiting valve should be used.

The PVHC is an electrical actuator module for main spool control.
The PVHC control is done by dual Pulse Width Modulated (PVM) high current supply 100-400 Hz PWM
control signals.
The hysteresis is affected by viscosity, friction, flow forces, dither frequency and modulation frequency.
The spool position will shift when conditions are changed such as temperature change.
Inlet with Hydraulic Pilot Pressure is needed.
Dither frequency with a certain amplitude is needed for optimal application performance.

PVE Series 7 Electrical Actuator
The analog PVE Series 7 is an electro-hydraulic actuator used to control a single work section of a PVG
proportional valve group. The PVE Series 7 actuator program includes variants with different
performance levels and features for PVG 32/100/120/128/256PVG 128/256.
The actuator positions the main spool in a PVG work section in order to control either the flow or the
pressure of the oil distributed to/from the work function. The control signal to the actuator is an analog
voltage signal, enabling the user to operate the work function remotely by means of a joystick, a
controller or the similar.
The analog PVE Series 7 actuator program features five different main hydraulic principle variants (PVEO/
PVEM/PVEA/PVEH/PVES). The different hydraulic principles combined with the different solenoid valve
regulation principles determine whether the actuator controls the spool proportionally according to a
demand signal or ON/OFF according to a voltage signal.
The electro-hydraulic solenoid valve bridge of the actuator is available in different designs utilizing
different regulation principles, depending on performance variant. The actuator positions the main spool
by distributing pilot oil pressure to either side of it, pressurizing one side by pilot pressure while relieving
the opposite side to tank and vice versa, as illustrated below. All proportional actuators feature a closed-
loop spool control and continuous fault monitoring.
The analog PVE Series 7 actuator program for PVG 128/256 features two different main hydraulic
principle variants (PVEO and PVEH). The different hydraulic principles combined with the different
solenoid valve regulation principles determine whether the actuator controls the spool proportionally
according to a demand signal or ON/OFF according to a voltage signal. The voltage control characteristic
of the PVE Series 7 actuators is shown in the figure below to the left.

PVEO overview
The PVEO actuator is a non-proportional ON/OFF control actuator with open-loop spool control primarily
used to control simple ON/OFF work functions where a proportional control of speed or oil flow is not a
requirement. The PVEO is available in two different performance variants, the standard PVEO and the
PVEO-R with ramp.
The standard PVEO functionality includes the simplest electric circuit of the PVG 128/256 actuator
program, using a fixed 12 Vdc or 24 Vdc supply voltage or signal voltage and a simple LED circuit to
control the LED light indicating Power ON/OFF.
The PVEO-DI variant includes an LVDT spool position monitor and a more advanced electric circuit with
an embedded micro-controller and separate power supply to handle the Direction Indication
functionality.
An energization of solenoid valve SV1 and a simultaneous de-energization of SV2 will cause the main
spool to move to the right direction and vice versa. If both SV1 and SV2 are energized or de-energized
simultaneously, the main spool stays locked in its neutral position.

PVEH
The PVEH actuator is a proportional control actuator with closed-loop spool control primarily used to
control work functions with high performance requirements.
The PVEH functionality includes an electric circuit with a closed-loop logic. An embedded micro-
controller processes the signal voltage and the LVDT feedback signal and regulates the solenoid valves
accordingly. Features such as active or passive fault monitoring, LED indicating fault state, error output
pin and Power Save are all default PVEH features.
A continuous modulation of solenoid valves NC1 and NO4 together, with a simultaneous energization of
NO2 and de-energization of NC3, causes the main spool to move to the right direction and vice versa.
When the main spool is stroked to the far right, a simultaneous energization of both NO2 and NO4 and
de-energization of both NC1 and NC3 locks the main spool in its stroked position. An emergency stop
activated when the spool is stroked will cause all solenoid valves to de-energize causing the main spool
to move back to its neutral position by means of the main spool neutral spring and the hydraulic
principle.

Fault reaction depending on the type of fault monitoring
Generic
Specific
The PVEA comes with a passive fault monitoring.
Passive and active fault monitoring refers to whether or not the actuator is reacting on the error when it
is detected.
Active fault monitoring
No matter what kind of error is detected, the solenoid valves will be disabled and the operation that the
valves/spool controls will stop immediately. Active fault monitoring keeps a “memory” of the error, even
if it is no longer registered. The active fault monitoring does not have Auto Recovery because of this
“memory” and a reboot/restart will therefore be required to reactivate the solenoid valves.
With an active fault monitoring the following scenarios will take place when an error is detected/occurs:
The LED light will switch from green to red and the error pin output will go high
The solenoid valves will be disabled and the operation that the valves/spool controls will stop
immediately
The active fault monitoring does not have Auto Recovery, so when the error is fixed/no longer is
registered a reboot/restart of the PVE is required to reactivate it.
Passive fault monitoring
Passive fault monitoring does not disable the solenoid valves when an error is detected. It will continue
to operate despite that an error was detected. When the error no longer is registered the passive fault
monitoring will “forget” the error and continue as if the error was never there.
With a passive fault monitoring the following conditions will happen when an error is detected/occurs:
The LED light will switch from green to red and the error pin output will go high
The solenoid valves will continue operating at the set point given at the time of the error
Only exception is if the error is caused by the supply voltage (U
DC
) being either above or below
the allowed range or if the temperature measured on the internal electronics board is higher than
allowed. In these cases, the solenoid valves will be disabled.
An overview of the error states and the reaction to the errors can be seen in the table Fault Reaction
Overview.
Generic Fault Reaction
All PVE actuators with fault monitoring are triggered by the following main events:
Control Signal Monitoring
The Control signal voltage (U
S
) is continuously monitored.
The permissible range is between 15% and 85% of the supply voltage (U
DC
).
Outside this range the PVE will switch into an error state. A disconnected U
S
pin (floating) is recognized as a neutral set point.
Transducer/LVDT Supervision
The internal LVDT wires are monitored. If the signals are interrupted or short-
circuited, the PVE will switch into an error state.

Supervision of Spool Position
The actual position must always correspond to the demanded position (U
S
).
If the actual spool position is further out from neutral than the demanded
spool position or in opposite direction, the PVE will switch into an error state.
Spool position closer to neutral and in same direction will not cause an error
state – the situation is considered in control.
Float Position Monitoring
Float position must be entered or left within a time limit.
A too high delay on the 1x6 pin float PVE will cause an error state – this is
relevant for the 1x6 pin PVEH-F actuators only.
Temperature Monitoring
When the temperature is too high the PVE LED will light constant red and
solenoid valves will be disabled.

PVE Power Save
All proportional actuator variants feature a Power Save mode, de-energizing the solenoid valve bridge.
The Power Save mode is entered when the signal voltage (Us) and the LVDT spool position has been in
neutral for 750 ms. As soon as the signal voltage (Us) or the LVDT spool position is out of neutral the PVE
will leave its Power Save mode and re-energize the solenoid valve bridge as usual.
The Power Save mode results in increased power efficiency by reducing the current consumption of the
PVE actuators in neutral position. The Power Save mode has no effect on the performance of the PVE
actuator.

Dedicated Float Pin (UF)
The Dedicated Float Pin (UF) feature is related to the PVEH-FLA actuator variant described in the chapter
Float A-Port. The PVEH-FLA uses 1x6 pin AMP or DEUTSCH connectors, as shown in the chapter Connector
Overview, enabling the user to move the main spool into its float position by powering a dedicated float
pin (UF).

Disable Mode
The PVEH-U/PVES-U actuator variants controlled by a fixed 0-10 Vdc signal voltage (Us), feature the ability
to enter a disable mode. This causes the counteracting force on the main spool created by the solenoid
valve bridge, when using manual override, to deactivate. The disable mode is entered by sending a signal
voltage (Us) of 16.2% of 10 Vdc when in Power Save.
For more information, please see Power Save.
