Proportional Valves Technical Information

Application Notes

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™ COMPLIANT Danfoss 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.

PROPORTIONAL FLOW CONTROL 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.

Current sensing resistor

Proportional Valves Technical Information

Application Notes

TERMS AND	Compensator is a hydraulic component that maintains a constant pressure drop across
DEFINITIONS	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 Current feedback circuit maintained.

Deadband is the range from zero to the	Solenoid
minimum current which causes the valve	Input
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.

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:

(88-80) = 5%

160

Imin is the minimum current required for valve response (see deadband).

Imax is the current required for maximum valve output.

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

Proportional Valves Technical Information

Application Notes

TERMS AND	PWM is an acronym for Pulse-Width-Modulation. Most valve drivers use a current
DEFINITIONS	controlled PWM which produces an average output that is a function of duty cycle in
(continued)	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 pre-
	programmed 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.

PSV10-34-02

OPERATION

This is a proportional, non-compensated, 3 position 4 way, directional flow control solenoid valve, with closed-center spool.

APPLICATION NOTES

These cartridge valves are typically applied to provide bi-directional, proportional control of hydraulic cylinders and motors where low leakage is not required. 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 back-pressure 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.

PSV12-34-02

OPERATION	Shown with Deutsch
This is a proportional, non-compensated, 3 position 4 way, directional	connector
flow control solenoid valve, with closed-center spool.
APPLICATION NOTES
These cartridge valves are typically applied to provide bi-directional,
proportional control of hydraulic cylinders and motors where low
leakage is not required. For load-independent flow control, apply with
a pressure compensator, such as HLE10-OPO (see Example Circuit). Port
1 should be used as the tank port, with a maximum back-pressure 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	Shown with DIN
tank oil level in the horizontal position, reducing the chance for trapped	connector
air in the valve.

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.
