Overview
Description
Features
Series ASC Anti Spin Control Valve
The Danfoss Anti Spin Control valve (ASC-valve) is used e.g. in a propel drive line. The flow provided by a
pump is split equally and ported to two propel motors, ensuring, both run at the same speed under all
load, pressure, flow, and vehicle steering conditions. This prevents wheel slip and provides optimum
vehicle traction. The ASC-valve concept allows therefore a wide variety of applications whenever equal
flow share is demanded.
The ASC-valve in conjunction with a SUSMIC S1X microprocessor as well as steering and speed sensors
combines the capabilities of modern digital electronics with the worldwide proven Danfoss hydrostatic
components, to enhance the machine performance and operation.
The microprocessor-based SUSMIC S1X provides software flexibility and is designed for the future. With
easy-to change parameters (in software) it is possible to make an individual setup for different machine
types.

System Pressure Range
Technical Information
Series ASC Anti Spin Control Valve
General Technical Specifications
Pressure Limits
System pressure is the dominant operating variable affecting hydraulic unit life. High pressure, which
results from high load, reduces expected life in a manner similar to the affects of high load on other
mechanical assemblies such as engines and gear boxes.
Continuous pressure is the pressure at which the hydrostatic system could operate continuously and still
achieve acceptable hydrostatic life. This pressure level varies depending on operating speed, and on the
life requirements for a particular application. While most mobile applications require system pressure to
vary widely during operation, a “weighted average” pressure can be derived from a machine duty cycle.
(A duty cycle is a means of quantifying the pressure and speed demands of a particular system on a
percent time basis). Once a duty cycle has been determined or estimated for a specific application,
contact your Danfoss representative for system life ratings for the application.
Maximum pressure is the highest intermittent pressure allowed, and is the relief valve setting. It is
determined by the maximum machine load demand. For most systems, the load should move at this
pressure.
Maximum pressure is assumed to occur a small percentage of operating time, usually less than 2% of the
total. Both the continuous and maximum pressure limits must be satisfied to achieve the expected life.
Hydraulic Fluids
Temperature and Viscosity
Ratings and data are based on operating with hydraulic fluids containing oxidation, rust and foam
inhibitors. These fluids must possess good thermal and hydrolytic stability to prevent wear, erosion and
corrosion of the internal components.
Fire resistant fluids are also suitable at modified operating conditions. Please see Danfoss literature
Hydraulic Fluids and Lubricants Technical Information for more information.
It is not permissible to mix hydraulic fluids. For more information contact your Danfoss representative.
The following hydraulic fluids are suitable:
Hydraulic Oil ISO 11 158 - HM (Seal compatibility and vane pump wear resistance per DIN 51 524-2
•
must be met)
Hydraulic Oil ISO 11 158 - HV (Seal compatibility and vane pump wear resistance per DIN 51 524-3
•
must be met)
Hydraulic Oil DIN 51 524-2 - HLP
•
Hydraulic Oil DIN 51 524-3 - HVLP
•
Automatic Transmission Fluid ATF A Suffix A (GM)
•
Automatic Transmission Fluid Dexron II (GM), which meets Allison C-3 and Catapillar TO-2 test
•
Automatic transmission Fluid M2C33F and G (Ford)
•
Engine Oils API Classification CD, SE and SF
•
Super Tractor Oil Universal (STOU) special agricultural tractor fluid
•
Temperature and viscosity requirements must be concurrently satisfied. The data shown in the tables
assume petroleum-based fluids are used.
The high temperature limits apply at the hottest point in the transmission, which is normally the case
drain. The system should generally be run at or below the rated temperature. The maximum temperature is
based on material properties and should never be exceeded.

Technical Information
Series ASC Anti Spin Control Valve
General Technical Specifications
Cold oil will generally not affect the durability of the transmission components, but it may affect the
ability to flow oil and transmit power; therefore temperatures should remain 16 °C [30 °F] above the pour
point of the hydraulic fluid. The minimum temperature relates to the physical properties of component
materials.
For maximum unit efficiency the fluid viscosity should remain in the recommended operating range. The
minimum viscosity should be encountered only during brief occasions of maximum ambient temperature
and severe duty cycle operation. The maximum viscosity should be encountered only at cold start.
Heat exchangers should be sized to keep the fluid within these limits. Testing to verify that these
temperature limits are not exceeded is recommended.
Fluid and Filtration
To prevent premature wear, it is imperative that only clean fluid enter the hydrostatic transmission
circuit. A filter capable of controlling the fluid cleanliness to ISO 4406 Class 22/18/13 or better under
normal operating conditions is recommended.
The filter may be located either on the inlet (suction filtration) or discharge (charge pressure filtration)
side of the charge pump. The selected filtration system must maintain a cleanliness level of 22/18/13 per
ISO 4406.
The selection of a filter depends on a number of factors including the contaminant ingression rate, the
generation of contaminants in the system, the required fluid cleanliness, and the desired maintenance
interval. Filters are selected to meet the above requirements using rating parameters of efficiency and
capacity.
Filter efficiency may be measured with a Beta ratio1) (βX). For simple suction-filtered closed circuit
transmissions and open circuit transmissions with return line filtration,
a filter with a β-ratio within the range of β
For some open circuit systems, and closed circuits with cylinders being supplied from the same reservoir,
a considerably higher filter efficiency is recommended. This also applies to systems with gears or clutches
using a common reservoir. For these systems, a charge pressure or return filtration system with a filter βrotation in the range of β
Since each system is unique, the filtration requirement for that system will be unique and must be
determined by test in each case. It is essential that monitoring of prototypes and evaluation of
components and performance throughout the test program be the final criteria for judging the adequacy
of the filtration system.
Please see Danfoss literature Hydraulic Fluids and Lubricants Technical Information for more information.
1)
Filter βx-ratio is a measure of filter efficiency defined by ISO 4572. It is defined as the ratio of the
number of particles greater than a given diameter (“x” in µm) upstream of the filter to the number of
these particles downstream of the filter.

General Technical Specifications
Independent Braking System
The loss of hydrostatic drive line power in any mode of operation (e.g., forward, reverse, or “neutral”
mode) may cause the loss of hydrostatic braking capacity. A braking system, redundant to the hydrostatic
transmission must, therefore, be provided which is adequate to stop and hold the system should the
condition develop.
Warning
Reservoir
The function of the reservoir is to remove air and to provide make up fluid for volume changes associated
with fluid expansion or contraction, possible cylinder flow, and minor leakage.
The reservoir should be designed to accommodate maximum volume changes during all system
operating modes and to promote deaeration of the fluid as it passes through the tank.
A minimum reservoir volume equal to 1/2 to 1 1/2 times charge pump flow/min is suggested. This allows
30 seconds fluid dwell for removing entrained air at the maximum return flow. This is usually adequate to
allow for a closed reservoir (no breather) in most applications. The reservoir outlet to the charge pump
inlet should be above the bottom of the reservoir to take advantage of gravity separation and prevent
large foreign particles from entering the charge inlet line.
The reservoir inlet (fluid return) should be positioned so that the flow to the reservoir is discharged below
the normal fluid level, and also directed into the interior of the reservoir for maximum dwell and efficient
deaeration.

General Description
ASC-Valve function
Series ASC Anti Spin Control Valve
The ASC-valve is used in anti slip systems for hydrostatic drive systems. It is possible to use this valve in
wheeled machines with up to 4 wheels driven individually. The ASC System is especially useful for
applications with fixed motors, but can also be combined with variable displacement motors.
The ASC System consists of a central digital controller Susmic S1X, speed sensors for each motor, the ASCvalve and steering sensors. It is important to note that in such system the amount of impulses per wheel
rotation should show the highest possible frequency resolution in order to be able to ensure a good
performance of the anti slip system.
The ASC-valve is of twin valve design and provides both motors with the required flow, generally these
are the 2 motors for one axle not mechanical connected. The input flow in P is divided and equally ported
to port A and B (see P001 968).
ASC-valve in neutral, no wheel slips
If for example the wheel connected to port “B” slips, the speed sensor detects this and sends a signal to
the Susmic S1X controller. The Susmic S1X controller then will provide current to the electric proportional
valve for port “B” and the spool in the ASC-valve closes the connection to port “B”, so a pressure drop
across this connection is build up equal to the pressure of the other wheel connected to port “A” minus
the pressure needed to drive wheel “B” (see P001 980). This limits the flow to wheel “B” and the wheel
stops to slip and runs at the same speed as the wheel connected to port “A”

Technical Information Series ASC Anti Spin Control Valve
Application Considerations
The following measures must be considered for proper anti spin function:
Remaining flow from the ASC-valve at maximum input current limits the minimum motor speed
•
(possible remaining motor slip).
Additional pressure limiter may be required if valve with low remaining flow at maximum input
•
current is used and valve is arranged in the return line of the motor.
When using more then one ASC-valve in an application either all valves must be placed in the supply
•
line of all motors or all valves must be placed in the return line of all motors.
Sum pressure for motors at downhill and deceleration condition must be considered.
•
Integrated loop flushing is not allowed because of potential sum pressure condition (high pressure
•
hydraulic fluid would be flushed out).

Series ASC Anti Spin Control Valve
Typical ASC-valves with order numbers 507 479 (12 VDC) or 507 832 (24 VDC) with a remaining flow of 12
l/min [3.17 US gal/min] are used. These valves meet most application requirements. Please note, that due
to the 12 l/min [3.17 US gal/min] remaining flow at 400 bar [5800 psi] the spinning wheel cannot be
completely stoped.
If it is required that wheel slip is near zero at max closed position, the ASC-valves with a remaining flow of
< 2 l/min [0.5 US gal/min] at 400 bar [5800 psi] are recommended. Order numbers for such valves are 507
831 (12 VDC) or 507 833 (24 VDC) for a maximum flow of 60 l/min [16 US gal/min]. However, high sum
pressure risk at downhill condition is higher.
In some cases it may be demanded, that the ASC-valve remains in max closed position, if voltage/current
supply is lost. This is typically the case if the emergency stop button is hit. The ASC-valve with order
number 518 033 (24 VDC), 60 l/min [16 US gal/min] and remaining flow of < 2 l/min [0.5 US gal/min] at 400
bar [5800 psi] provides a separat LX port.
Scematic ASC-valve 518 033
In order to hold the ASC-valve in closed position this LX port may be closed by a solenoid valve which is
closed when not activated. This maintains the pressure acting on the main spool and keeps it closed.
Please note, that this causes the other spool to close as well. Carefully check the impact on the
application.

Spool stroke versus current
Due to tolerance stack up the spool may start to close (start to shut off one motor) already at 200 mA or
may need 300 mA (24 VDC option). To make sure the valve is securely open when the anti spin function is
not needed, the standby current has to be limited to 300 mA for 12 VDC and 150 mA for 24 VDC.
These tolerances furthermore have an impact on the maximum spool closing position. The valve may
need 650 mA for 24 VDC respectively 1300 mA for 12 VDC to be at maximum closed position.
