PVG 16 Proportional Valve Group
General Information
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 PVG 16 is a member of the PVG product platform and interfaces to other valve families enabling all
machine functions being controlled from one single valve stack.
PVG 16 controls work port flow up to 65 l/min [17 US gal/min] l/min and up to 420 bar [6090 psi] bar work
port pressure.
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.
PVG 16 Features
PVG load-sensing proportional valves features and benefits summarized in bullets below:
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
‒
Inlet flow up to 140 l/min [37 US gal/min] 230 l/min [61 US gal/min] when used with mid-inlet
•
Easy integration with PVG 32
•
Possible combination with the rest of the PVG family, when using an interface module
•
Up to 12 basic modules per PVG 16 valve group
•
Reliable regulation characteristics across the entire flow range
•
Load sense relief valves for A and B port enables reduced energy loss at target pressure
•
Several options for connection threads and flange mount
•
Compact design, easy installation and serviceability

PVG 16 Proportional Valve Group
General Information
Safety in Systems
All types and brands of control valves, including proportional valves, can fail. Therefore, the necessary
protection against the serious consequences of a functional failure should always be built into the
system.
General safety considerations
For each application an assessment should be made for the consequences of the system in case of
pressure failure and uncontrolled or blocked movements.
Warning
Because the proportional valve is used in many different applications and under different operating
conditions, it is the sole responsibility of the manufacturer to ensure that all performance, safety and
warning requirements of the application is met in his selection of products and complies with relevant
machine specific and generic standards.
Control system example
An example of a control system using an aerial lift is shown below:
Aerial lift
This example breaks down the control system into smaller bits explaining the architecture in depth. Even
though many Danfoss components are used in the PVG control system.
The function of the control system is to use the output from the PVE together other external sensors to
ensure the PLUS+1 main controllers correct function of the aerial lift.

Warning
It is the responsibility of the equipment manufacturer that the control system incorporated in the
machine is declared as being in conformity with the relevant machine directives.
Caution
A mix of electrical actuation and hydraulic actuation on the same valve stack is not safe. PVE and PVH are
designed for different pilot pressure.
Cost-free repairs, as mentioned in Danfoss General Conditions of Sale, are carried out only at Danfoss or
at service shops authorized by Danfoss.

PVG 16 Proportional Valve Group
PVP Inlet Modules
Open center PVP with HPCO and PVE PPRV
The Open Center PVP inlet with integrated High Pressure Carry Over (HPCO) functionality is intended for
use with fixed displacement pumps in applications where one pump supply for multiple hydraulic
subsystems is desired.
The integrated HPCO functionality guides the excess flow of the PVG 16 valve group to the external
hydraulic subsystem(s), giving priority to the PVG 16 work functions.
The Open Center PVP with HPCO and PVE PPRV features:
Integrated LS pressure relief valve
•
Threaded ports for P/T/LS/HPCO and M measuring gauge
•
Integrated pilot pressure reducing valve (PPRV) for PVE
•
Optional T0 facility and external T0 port
•
Optional external pilot pressure port (Pp)
•
Optional LS unloading valve, PVPX
•
Models with T0 port have internal T0 connection closed by default.
•
Only applicable with PVST end plates with separate T-port due to blocked T-lines for HPCO functionality.

PVP Inlet Modules
Open/Closed center PVP with PPRV
The Open Center/Closed Center PVP with integrated pilot pressure reduction valve (PPRV) is intended for
use with fixed or variable displacement pumps in applications where the application manufacturer does
not determine the pump type.
The modules allow an easy switch between Open Center and Closed Center configuration by means of an
external hexagon selector key. Variants also feature an LS boost functionality, increasing the LS pressure
to the pump LS regulator with a constant 6 bar, compensating for potential LS bleed-off and leakage.
The Open/closed center PVP with PPRV features:
Integrated OC/CC selector
•
Integrated LS pressure relief valve
•
Threaded ports for P/T/LS and M measuring gauge
•
Integrated pilot pressure reducing valve (PPRV) for PVE or PVH/PVHC
•
Optional LS boost functionality
