Cartridge Valves Technical Information Introduction
Cartridge Valves
CARTRIDGE VALVE INTRODUCTION
Cartridge valves are compact and economical components that can be used for directional, pressure, or ow control in systems from 0.4 L/min [0.1 US gal/min] up to 400 l/min [100 gpm], and for pressures up to 350 bar [5000 psi]. By combining standard cartridge valves almost any hydraulic circuit can be easily created. Using cartridge valves in a custom manifold, a designer can create a hydraulic integrated circuit (HIC) that provides a compact package for hydraulic control with reduced plumbing, easier installation, easier service, and fewer leak points than traditional hydraulic systems.
Each valve has several key ratings, specications, and settings:
· Each Danfoss ICS cartridge valve ts a Danfoss ICS standard cavity. These cavities are designed around SAE or metric standard o-ring straight thread ports. In many cases these cavities are interchangeable with cavities used by other manufacturers. See catalog sheets for details.
· The pressure rating is based on NFPA T.2.6.1 fatigue test standards and a burst test with a minimum safety factor of 3:1
· The ow rating is based on the ow at a pressure drop of 7 bar [100 psi] for directional valves or a pressure rise or drop of 7 bar [100 psi] for pressure relief and reducing valves, with 32 mm2/s (cSt) [151 SUS] uid. Note that for many valves this ow can be exceeded if the resulting higher pressure drop and the associated heat generation are acceptable. The exceptions to this are solenoid-operated spool­type directional valves and proportional ow control valves where the ow ratings indicate a performance limit.
· The solenoid voltage is a nominal value. All solenoid valves are designed to operate at 85% of nominal voltage with full rated ow and pressure and at an ambient temperature of 40 °C [104 °F].
· Pressure settings for check, relief, reducing, sequence, and motion control valves, commonly referred to as the crack pressure, are set at a ow rate of 0.95 L/min [0.25 gpm] through the valve.
· Leakage is generally measured at rated pressure limits or in the case of relief and motion control valves at 70-80% of crack pressure setting, with 32 mm2/s (cSt) [151 SUS] uid. See individual catalog sheets for details.
· Temperature ratings vary by model and options. Seal materials provide ranges of -40 °C to 100 °C [-40°F to 212 °F] (buna-n or polyurethane) or -26 °C to 204 °C [-15 °F to 400 °F] (viton). The recommended minimum uid viscosity is 12 mm2/s (cSt) [66 SUS] which will override the maximum seal temperature limit for most uids. Solenoid valves are rated for 60 °C [140 °F] maximum ambient temperature for continuous duty. Consult factory for extreme applications.

Cartridge Valves Technical Information Introduction
Fluid and ltration recommendations
FLUIDS
FILTRATION
Ratings and performance data for cartridge valves are based on operating with premium hydraulic uids containing oxidation, rust, and foam inhibitors.
These premium uids include premium turbine oils, API CD engine oils per SAE J183, M2C33F or G automatic transmission uids (ATF), Dexron II (ATF) meeting Allison C-3 or Caterpillar TO-2 requirements, and certain specialty agriculture tractor uids. For further information see Danfoss publication 520L0463, Hydraulic Fluids and Lubricants Technical
Information.
CAUTION Never mix hydraulic uids.
Product performance will generally be within catalog limits with uids meeting the recommended viscosity limits shown below.
Product can be operated at viscosities outside the recommended limits, however performance may be greatly degraded. Extreme conditions must be evaluated by the user to determine acceptibility of product performance.
Contact your Danfoss ICS representative for more information regarding uids.
It is imperative that only clean oil be used with cartridge valves to maintain valve operation and prevent premature wear. System ltration capable of controlling the uid cleanliness to the limits shown below is required.
The selection of lters depends on a number of factors including the contamination ingression rate and the desired maintenance interval. Filters are selected to meet the below requirements using rating parameters of eciency and capacity.
Filter eciency may be measured using a Beta (β) ratio.* A lter with a β-ratio within the range of β10=10 is typically required.
Since each system is unique, the ltration 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 nal criteria for judging the adequacy of the ltration system. For further information see Danfoss publication 520L0467, Design Guidelines for Hydraulic Fluid Cleanliness
Technical Information.

* Filter βx ratio is a measure of lter eciency dened by ISO 4572. It is dened as the ratio of the number of particles greater than a given size (x) upstream of the lter to the number of particles greater than the same size downstream of the lter. The βx ratio applies to a specic particle size, measured in microns.

CAVITY PORT IDENTIFICATION
Refer to specic pages within this catalog to ensure proper port identication for cartridge functions. Inspect the valve cavity to be sure it is free of burrs, chips or other contamination.
Check the cartridge to ensure it is free of external contamination, and the O-rings and back-up rings are intact. Dip the cartridge in clean oil to the top of the threads to lubricate the O-rings.
Insert and screw the cartridge into its cavity by hand. It should turn easily up to the top O-ring. If it does not turn easily, the cavity has been machined improperly and the body should not be used.
Torque all cartridges per specication shown on catalog sheet. Torque all coil nuts to 5-8 N•m [4-6 lbf•ft] unless otherwise specied.
Test the entire system to ensure that the cartridges are performing correctly and to check for leaks.

Hydraulic integrated circuits
DESCRIPTION
DESIGN CAPABILITIES
Cartridge valves can be installed in custom designed manifolds to create a Hydraulic Integrated Circuit (HIC). HICs provide many advantages over traditional hydraulic
control systems:
· HICs are compact packages that simplify machine plumbing, reducing costs for ttings, tubes, hoses, and installation.
· Leak points are eliminated.
· Service time and costs are dramatically reduced. Components can be replaced without disturbing machine plumbing.
· HICs can be centralized on a machine or strategically located near a function. Using a custom HIC provides the designer unlimited exibility to optimize machines for assembly, plumbing, wiring, service, and weight distribution.
A custom HIC can be specied and designed to meet your circuit requirements using Danfoss’s EasyManifold tool.
· EasyManifold allows you to eortlessly create your hydraulic circuit schematic from Danfoss’s digital library of cartridge valves using a drag and drop interface.
· With the new Automatic Design feature, small to medium sized HIC designs can now be completed through the tool. At the click of a button, your project can be submitted and EasyManifold will generate a 2D drawing and 3D model. In less than an hour, you can take your project from a concept to a design ready for manufacturing.
· For larger HICs, manifolds are designed using our state of the art CAD software by our regional HIC engineering design teams.
HICs can be designed with custom interfaces to mount directly to other Danfoss
products, including stackable spool valves and motors. This provides a compact and ecient hybrid solution to meet your machine requirements.
Industry-leading rapid prototyping is available globally to support your program
requirements.
