PROPORTIONAL VALVES
Proportional, or electro-proportional valves, provide infinitely variable control of flow,
pressure, or direction, in response to a electric input signal.
There are four basic types of Danfoss ICS proportional valves:
• Flow control valves.
• Pressure reducing/relieving valves.
• Pressure relief valves.
• Directional control valves
Proportional valves
PLUS+1™ COMPLIANTDanfoss ICS solenoid valves are PLUS+1™ compliant. PLUS+1 compliance means our
valves are directly compatible with the PLUS+1 machine control architecture. Adding
solenoid valves to your application using PLUS+1 GUIDE software is as easy as drag-and-drop. Software development that used to take months can now be done in just a
few hours. For more information on PLUS+1 GUIDE, visit http://powersolutions.danfoss.com/Applications/PLUS1Compliance/index.htm. The table below details available GUIDE
function blocks for controlling Danfoss ICS solenoid valves.
Danfoss ICS proportional flow control valves are 2-way, spool-type valves that are
directly operated with a proportional electromagnetic solenoid actuator. By controlling
electric current, these valves create an infinitely variable orifice.
Proportional flow control valve
These valves are designed to be used with a logic element to provide pressure
compensation. Pressure compensation provides two advantages:
1. A constant pressure differential is maintained across the proportional valve (variable
orifice), which maintains constant flow regardless of changes in operating pressure
or load.

2. A constant pressure differential

Typical circuits use restrictive-type or priority-type pressure compensators with
proportional flow control valves to control speed of a hydraulic motor or cylinder.
Proportional flow control valves are available with a variety of flow capabilities (variable
orifice sizes). By matching this flow capability to various pressure compensator settings,
a wide range of flow vs. current control curves can be attained.

PRESSURE REDUCING/
RELIEVING VALVES
Proportional pressure reducing/relieving valves are 3-way valves that provide a
controlled output pressure as a function of electric current, regardless of system pressure
or flow (within the valve’s limits). Direct acting designs are available for low-flow
applications.
• Single acting cylinder position
control, e.g. combine header height
control.
• Clutch or brake pressure control.
• Pilot signal to a directional control
valve. By slowly ramping the current

to the proportional valve in this
example, a soft-start and soft-stop is
attained.

Current
Application Notes
TERMS AND
DEFINITIONS
Compensator is a hydraulic component that maintains a constant pressure drop across
a fixed or variable orifice.
Current is the flow of electricity through a conductor or coil, normally measured in amps
(A). Steady-state current flow in an electrical circuit can be calculated by Ohm’s Law, as
well as voltage and resistance.
Ohm’s Law I =
V
R
Current Control is a feature of almost all valve drivers. The output of analog
proportional valves is a direct function of current. If a valve is controlled with voltage,
higher solenoid temperatures, which increase solenoid resistance, will result in lower
valve output. To compensate for this, most valve drivers are designed with current
feedback circuitry. This means that as solenoid temperature rises or as supply voltage
and voltage losses change, the current
and corresponding valve output are
maintained.
Deadband is the range from zero to the
minimum current which causes the valve

to respond.
Digital Proportional Valves are
extremely fast responding valves that are controlled by a precise on-off signal to
produce an average output that is a function of duty cycle.
Application Notes
Dither is a “ripple” signal sent to a solenoid to reduce hysteresis. Dither can be a sine,
square, or saw-tooth wave superimposed on a PWM signal or it can be a wave on top of
a DC signal.
Duty Cycle is the % of time the valve is on divided by total time.
Hysteresis is the difference in output for a given input, depending on whether the
input is increasing or decreasing. It is normally expressed as a % of the maximum
rated output. For example, if a 160 l/min 42 US gal/min proportional flow control valve
provides 80 l/min 21 US gal/min with 1 amp-increasing and 88 l/min 23 US gal/min at 1
amp-decreasing, the hysteresis is:

Proportional Valves are analog devices controlled by electric current which may be
direct current (DC) or a PWM signal.

DEFINITIONS
(continued)
PWM is an acronym for Pulse-Width-Modulation. Most valve drivers use a current
controlled PWM which produces an average output that is a function of duty cycle in
order to reduce valve hysteresis and to allow current control without excessive heat
generation. A typical PWM output is a square wave from 80-500 Hz.
Ramping is the application of current to a solenoid with a linear or non-linear ramp,
rather than an instantaneous step. Ramping current on and off to a proportional valve
provides actuators with soft-starts and soft-stops. Ramps can generally be set or preprogrammed into valve drivers.
Resistance is a component’s opposition to the flow of electrical current, usually
measured in ohms (Ω). Resistance depends on the conductivity of the material, as well
as size, shape, and temperature. Solenoid resistance can vary greatly with temperature;
to compensate for this, current-controlled drivers are generally always used with
proportional valves.
Threshold is the minimum current required for valve response; see deadband.
Valve Driver is a generic term for any device that sends a signal to a proportional valve.
A valve driver may range from a simple electronic circuit attached to a knob or lever up
to a microcontroller with custom software and multiple inputs and outputs.
Voltage is the potential for current to flow in an electric circuit, usually measured in
volts (V).

MANUAL OVERIDE
MANUAL OVERIDES
OPTIONS
Danfoss ICS proportional flow control valves, where noted in the individual
catalog pages, have optional manual overrides - “SPS” and “PB” (note
that it if the valve has a manual override option, it comes standard with
a push-pin style override). The manual overrides are “safety” features for
when power is lost and the proportional valve needs to be operated. If
using the “SPS” option, the screw-style manual override can be used to
proportionally adjust the flow setting when no power is supplied to the
coil. When using the “PB” option, the push-button manual override will
push to fully open or fully close the valve, which can send full flow, or
cut-off the flow to the system. So caution must be taken when applying
in a proportional system. The “SPS” proportional control is preferred. The
manual overrides, when activated, shift the valve to its energized position.
Standard for any valve with push-pin manual
override feature, where indicated in the catalog.

PSV10-34-05
OPERATION
This is a proportional, non-compensated, 3 position 4 way,
directional flow control solenoid valve, with float-center spool.
APPLICATION NOTES
These cartridge valves are typically applied to provide
bi-directional, proportional control of hydraulic cylinders and
motors. In applications requiring load-holding, PO checks or
counterbalance valves can be added to provide a low leakage
solution. For load-independent flow control, apply with a
pressure compensator, such as CP700-4 (see Example Circuit).
Port 1 should be used as the tank port, with a maximum backpressure of 150 bar. For applications with unequal flows, the
highest flow should be connected to Port 2.
Note: For optimal performance install with the solenoid valve
below the tank oil level in the horizontal position, reducing the
chance for trapped air in the valve.

Proportional Valves Technical Information
Proportional Flow Divider
PFD10-OD
OPERATION
PDF10-OD: Proportional Flow Divider, 10 Size, Normally Open, Divider
This is a proportional, compensated, normally open, flow dividing, preengineered HIC. When there is no current applied to the coils, the inlet flow
is divided equally between ports A and B. As an example, if inlet flow is 40
LPM, the flow out Ports A and B will divide equally 20 LPM. The performance
curve below shows input flow examples of 40, 20 and 10 LPM. Minimum
inlet flow is 10 LPM (2.6 GPM). The flow ratio between ports A and B will
proportionally vary as current is provided to coils S1 or S2. As current
increases to coil S2, the flow to Port B will proportionally increase, while Port
A decreases, as shown in the graph. Inversely, as current increases to coil S1,
the flow to Port A will proportionally increase, while Port B decreases.
Note that this is not a combiner, the flow only exits Ports A and B. Connect the drain port DR to tank, limiting the
pressure on this port to 50 bar (720 psi).
APPLICATIONS
Proportionally divide the input flow between two motors or hydraulic circuits (like HICs). Circuits that can take
advantage of this pre-engineered HIC include any function where the motors or the HICs continuously require
flow, and you only need to proportionally manage the amount of flow between them. Achieve repeatable, loadindependent flow dividing with the built-in pressure compensator. See performance curve below for compensation
capabilities.
Note: For optimal performance, install with the solenoid valve in the horizontal position, reducing the chance for

Proportional Valves Technical Information
PPR09-POD
OPERATION
Proportional Pressure Reducing / Relieving Valve, Pilot Operated, Normally Open to Drain.
With no current to the coil, the “reduced pressure” (port 3) is connected to drain (port 4), while
blocking the inlet (port 2). As current is increased to the coil, inlet (port 2) is connected to
“reduced pressure” (port 3), proportionally increasing the “reduced pressure” as shown on the
performance curve(s). If the “reduced pressure” exceeds the setting induced by the coil, pressure
is relieved to drain (port 4). This 09 Series valve uses a 10 size cavity with an 08 size tube and coil,
providing an optimal product for high flow and low pressure, while minimizing pressure drop in
the system. This valve was formerly branded as XRP 044.
APPLICATION
Common applications include low-pressure proportional pilot control of clutches or hydraulically
piloting large directional spool valves. Refer to example circuits. Use the optional screen to help
protect the actuator from large particles. Select the robust coil for those extreme environmental
conditions – voltage extremes, high temperature, shock & vibration, chemicals, and/or water
ingression.
