Introduction
Short overview
PVG 32 AG Modules
The PVG 32 valve was originally launched with a range of high-performance electrical actuators in 1988.
During recent years, several AG (agricultural) customer projects have motivated several innovations, and
today our valve program offers components and features as compiled in this Technical Information or
referred to the Literature reference.
Metric ports
We have developed a range of modules with metric ports. These modules comprise of various inlets,
working modules for auxiliary functions, hitch modules, special top mounted modules and endplates.
The range of our PVE - Series 4 is used as actuation.
The target application area for this product range is mainly Agriculture – especially complete EH valve
solutions for tractors, but also other applications can benefit from the offered features.
Besides the inlets suited for fixed as well as for LS-controlled variable piston pumps, you will find a range
of valve modules listed. These valves enable you to assemble a valve solution using EH Aux valves and
hitch valves for tractors.
The PVE Series 4 generation with either analogue and digital pilot heads offers multiple possibilities of
customizing valves for individual needs – ranging from simple analogue versions to fully ISOBUS
compliant actuators with numerous variants in between, analogue as well as digital.
PVG 32 parts description
Hitch control
Together with the introduction of this product range, Danfoss has developed a hitch control SW block
available in our PLUS+1® GUIDE which on base of a PLUS+1 controller can offer a Hitch control system for
tractors.
These components allow for design of hitch systems that incorporate intuitive control as well as a
number of innovative new solutions. The components available offer significant advantages in
controlling both the single and double acting systems, including easy understanding of both Force and
Slip control. In addition to performing state of the art operation of hitch, the software block contains logic
that ensures the full potential of the Danfoss hitch valves are exploited.
The technical information references mentioned describes the Danfoss concept behind the operation of
a hydraulic hitch system, and the different types of systems and components available from Danfoss.

Technical Information
Function
PVG 32 AG Modules
When main spools (15) are in neutral position, the pilot operated check valves (hereafter PO Check
valves) are kept closed by a spring plus the work port load, which is directed to the spring side of the PO
Check valves (14) via a small orifice.
If a main spool is actuated to have flow out of the B port, the meter out flow forces the respective PO
Check valves valve to open. At the same time, pilot pressure is guided via the main spool to the back side
of a small pilot valve (12) on the A port side. This will ensure that the load pressure behind the PO Check
valves is released to a separate tank T0 (20) via a seat valve and allow the PO Check valves to open and let
return flow pass across the main spool back to tank.
For float function, both PO Check valves are released to tank at the same time as described above.
In some applications with low load pressure, it is necessary to force open the PO Check valves by a pin
(17). This pin is actuated by means of pump pressure on the A port side.
PVBZ modules cannot be optionally mounted (PVM on A - Port side only).
The separate tank connection T0 is needed to ensure proper performance of the PO Check valvess
regardless of the pressure in main tank line T. It is therefore necessary to connect the T0 port in the Inlet
PVP direct to the oil reservoir with a separate hose, see dimensional drawing examples.
All the valve modules in this technical information have a T0 gallery.
Warning
When using PVP with HPCO function (T port can be pressurised) please make sure to lead return flow
from the A and B ports to tank via a separate tank port in the end plate PVST.
Warning
All makes and all types of directional control valves – inclusive proportional valves – can fail and cause
serious damage. It is therefore important to analyse all aspects of the application.
Because the proportional valves are used in many different operation conditions and applications, the
manufacturer of the application 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 level – could e.g. be governed by ISO 13849
(Safety related parts of control system).

PVBZ basic module for EH auxiliary valve functions
The PVBZ valve is a load and pressure compensated valve module with two pilot operated check valves
(PO Check valves) in the A- and B-ports. These are limiting the work port leakage to a very low limit,
below 1 cm3/min.
PVBZ modules will always have 2 PO Check valves one in each work port.
Besides compensation, the pressure compensator can limit the work port pressure blow up to 4 - 5 bar.
The special PVBZ load compensated module was developed for applications that require integrated pilot
operated check valves in the work ports that required to limit the port leakage to zero. See Technical data.
The PVBZ basic module can be mixed with basic modules PVB (with additional tank line T0).
Features:

PVBD, PVBZ with optional diverter feature
The utilization of a PVBZ module can be further enhanced by adding a diverter valve. Mounted on top of
the PVBZ valve slice, a 6/2 PVBD diverter valve can direct valve flow to either of two set of ports (A1/B1 or
A2/B2). The PVBD diverter spool (shift spool) is actuated by the PVC solenoid valve by means of pilot
pressure.
Features:

•

•
Pilot operated with PVC
•
Auxiliary valve on tractors for function control on implements: cylinder positioning when the demand
•
on neutral port leakage is limited.
PVBD, PVBZ with optional diverter feature
Principle description of PVBD diverter:
PVC off: The shift spool is held in position (flow to A1/B1) by the spring in the right hand side
•
(opposite the PVC). The spring chamber is always connected to the T0 gallery in the PVBZ body.
PVC on: Pilot pressure is led into the chamber next to the PVC. A limited flow is passing through the
•
shift spool and the two orifices and into the spring chamber connected to T0. Pressure-drop across
the orifices creates the shift force moving the shift spool towards the spring. As a result, port A2/B2
becomes active.
Leakage (along the spool clearance) from pressurized work ports A1/B1 or A2/B2 will always be drained
to T0 either directly in the spring chamber or through the shift spool. This secures safe positioning of the
shift spool as leakage never will build up pressure up in the control chambers.
Safety recommendation: Shift of the diverter should only be possible when the main spool is in neutral.
This has to be ensured through a proper set-up in the controller/MMI hardware.

PVBZ-HS/HD, hitch control valves
General introduction
Two types of hitch valves are available for hitch or similar applications. The two valve options offered are
the PVBZ-HS, single acting and the PVBZ-HD, double acting.
The PVBZ-HS matches the market standard whereby implements are raised hydraulically and lowered
only by the pull of gravity. The PVBZ-HD has the unique ability to raise and lower either as single- or
double-acting.
The benefits of the PVBZ-HD reflect a departure from old hitch norms - increased comfort when attaching
implements due to the same speed up and down and safer detachment of heavy implements from the
driver’s seat.
The full benefit of the possibilities with the PVBZ-HD is easily obtained by use of the PLUS+1® hitch core
application block. The core application block shifts the valve between single- and double-acting hitch
according to the most suitable operation.
The operator will not have to select the operation but will notice the benefits during normal operation of
the hitch. Work-modes are single-acting as it is standard today, but manual operation up and down are
double-acting to increase comfort, functionality and safety.
For further info and more details please see the Danfoss Hitch control System description, see Literature
reference.
PVBZ-HS basic module (hitch single-acting)
Single acting PVBZ-HS slice for standard hitch application.
It has its own tank port to direct the return flow directly into the tank with a minimum of back pressure.
This prevents tank-line pressure influence, especially when lowering the un-loaded (empty) hitch under
cold conditions (high oil viscosity).
Similar to the auxiliary slice, the single acting PVBZ-HS slice is a pressure-compensated valve slice with
one P/O check valve on B-port only. The same technology as in the PVBZ module is used.
Besides the flow paths, the spool is directing the pilot pressure to the pilot valve for P/O check valve
pressure release as well as to the shuttle pin in order to force the P/O popped to open under low load
conditions. This ensures a fully open flow path in lower mode.
The B-port is normally equipped with a PVLP shock valve.
PVBZ-HS incorporates a compensator with bleed-off to prevent pressure building up between the pump
gallery and the work ports.
A special 3/3 spool with optimized flow characteristics, both in meter-out as well as in meter-in direction,
has to be controlled by a high performance actuator.
Features:
Low leakage work port
•
Separated tank port
•
Integrated PVLP shock/anti cavitation valves
•
Can be mixed with PVB/ PVBZ with T0 gallery
•

•

Safety recommendations for the OEM and user.
To avoid unintended raise of the empty hitch the tank port on PVBZ-HS always has to be connected
direct to tank without any restriction or pressure build up possibilities.
This also ensures lowering in lower mode under cold conditions (high viscosity oil).
In case of manual actuation of the Hitch function (limp home mode) the power supply to the PVE has to
be disabled before the PVM (hexagon) can be actuated.
The OEM /end user needs to be aware of the dangerous operation when performing manual raise/
lowering of the hitch and be close to the hitch arms.
The double-acting hitch slice consists of the PVBZ valve-section with a flanged-on single/double-acting
selector (multi-valve) actuated by a PVC valve.
By energizing or de-energizing the PVC, the multi-valve shifts the slice between single- or double-acting
work-modes. This is of great benefit in hitch applications both for rear and front hitches. When the slice is
operating as single-acting, the A-port is connected to tank in the PVBZ body.
The PVBZ base of the PVBZ-HD has similar features as the PVBZ valve-slice. That is PO Check valves for low
leakage as well as compensator with bleed-off to eliminate pressure build-up between compensator and
work-ports.
