VISCOSITY

In this section you will find a variety of technicalinformation pertinent to general hydraulics as well as
cartridge valve technology.

Catalog data is from tests conducted on mineral oil at
a viscosity of 30 cSt (140 SSU) using an ISO VG:46
test fluid.

HYDRAULIC FORMULAS

Product should ideally be used at viscosities in therange of 15 to 50 cSt (80 to 230 SSU).

Below are a few of the common hydraulic formulas toassist you in calculating the requirements for yoursystem:Flow = Volume ÷ Unit of Time

Product will perform with reduced efficiency in theranges, 5 to 15 cSt (42 to 80 SSU) and 50 to 500 cSt(230 to 2300 SSU). These extreme conditions must be
evaluated by the user to establish suitability of the
product’s performance.

RATINGS & TESTING
All Parker cartridge valve products have been performance tested with the results shown on the individual
valve catalog pages. The performance data shown
represents typical operation characteristics of the
product. In addition, our valves are endurance tested.
Validation is conducted by testing or similarity indesigns.
Note: Not every cartridge option is endurance tested.
In other words, one three way spool is endurance
tested, and the others are assumed by similarity.

TEMPERATURE RATINGS
Product operating limits are broadly in the range -30°C
to 150°C (-20°F to 300°F) but satisfactory operation
within the specification may not be accomplished.
Leakage and response will be affected when used attemperature extremes and it is the user’s responsibility
to determine acceptability at these levels.

TD

THERMAL SHOCK
It is unreasonable to expect product to withstand rapid
temperature changes - this could affect both performance and life and care should be taken to protect the
product from such situations.

SERVICE & COMPONENTS
One of the advantages of integrated hydraulic circuits
is their serviceability. Should a valve need to be
replaced for any reason, a user only needs to unscrew
the valve from the manifold and screw the replacement
into the cavity. As such, there are few replacement
parts available for the Parker cartridge products. As
with any hydraulic system, the operator should bleed
off any trapped pressure and consult machine service
manuals prior to service. Parker does not offer any
service parts for internal components, but external
components such as coils, knobs, and seals areavailable.

LIMITATIONS IN USE
Parker cartridge valves are designed for a wide variety
of industrial and mobile applications. Despite theirflexibility, Parker Hannifin does not recommend or
support the use of our cartridge valves in any onhighway or aerospace applications. We also do notrecommend our products for use in the transport of
explosive products or in hazardous environments.

LM

LE
Logic
Elements“D”-Ring (4301 Polyurethane RESILON™ Material)
The “D”-Ring is the standard seal material on theWinner’s Circle threaded cartridge valves. The “D”Ring is molded of a special 4301 Polyurethane
RESILON™. Polyurethane materials exhibit better
wear resistance and tensile strength than standard
Nitrile or Fluorocarbon material. In addition, it has an
excellent resistance to compression set. This increased strength eliminates the need for back-ringsand simplifies installation.

The unique shape of the Parker “D”-Ring also provides
a variety of design advantages. The seal is molded into
a “D” shape where the seal is higher in the middle andlower on the ends. This prevents the seal edge fromfolding over on a corner inside the manifold during
installation. In addition, this design has a minimal lip,
thus, friction is reduced. Another unique feature of the“D”-Ring is its symmetrical design, resulting in no
performance degradation from the reverse direction, or
worry of backward installation. The “D”-Ring is also
equipped with “pressure pedestals” to reduce theeffects of “blow-by” common in reverse cycling. The pressure pedestals increase the sealing capability of the“D”-Ring, by reducing the radial pressure forces thatcompress the sealing face of the o-ring. The drawing
below depicts the shape and highlights the features.

You should match the seal compatibility to the temperature and fluid being used in your application.
Parker offers three seal materials to meet your application requirements. Parker’s standard material is a 4301
Polyurethane RESILON™ material “D”-Ring. We alsooffer Fluorocarbon and Nitrile seals. A brief synopsis ofeach seal material is given below to help you choose
the best seal for your application.

Thus, the “D”-Ring outperforms standard polyurethaneo-rings, especially when using high water content fluids
at elevated temperatures. The “D”-Ring is compatible
with most water-glycol, water/oil emulsions, and highgrade petroleum based hydraulic fluids at temperatures between -45°C to +93°C (-50°F to +200°F)

Parker recommends using top-quality mineral based orsynthetic hydraulic fluids with lubricating properties at
viscosities of 45 to 2000 SSU (6 to 420 cSt) at 38°C
(100°F). The absolute viscosity range 80 to 1000 SSU(16 to 220 cSt.). Fluids should have high anti-wear
characteristics and be treated to protect against
oxidation.

Hydraulic systems that include Parker valves should
be carefully protected against fluid contamination. The
proper cleanliness level for Parker cartridge valves
should be maintained at an ISO cleanliness level of
18/16/13.

Pressure
Controls

75% of all system failures are a direct result of contamination. Contamination interferes with four functionsof hydraulic fluids.
1. To act as an energy transmission medium.
2. To lubricate internal moving parts of components.

Logic
Elements

3. To act a heat transfer medium.

A number of interrelated system factors combine todetermine proper media and filter combinations. To
accurately determine which combination is ideal foryour system, all these factors need to be accountedfor. With the development of filtration sizing software
such as Parker inPHorm, this information can be used
to compute the optimal selection. In many instances
the information available may be limited. In thesecases, “rules of thumb” based on empirical data andproven examples are applied to get an initial starting
point.

HYDRAULIC FILTRATIONLEDCThere is no direct correlation between using a specific
ISO cleanliness classification. Numerous other variables
should be considered such as particulate ingression,actual flow through filters, and filter location.

4. To seal clearances between moving components.
A properly selected filter will provide adequate protection and reduce operating cost. This is achieved byincreasing the expected life of the valves and reducing
the cost of maintenance and repairs. Operation will besmoother and more precise.

APPLICATION OF PRODUCTCAUTION - It is important to note that the Parker
Hydraulic Cartridge Systems Division makes a varietyof valves, many of which fit into the same cavity.
However, their functionality may differ considerablyfrom one valve type to another. Accordingly fit
interchangeability does not necessarily mean formor function interchangeability. Users should ensurethat the appropriate valve is installed in the cavity bycross checking the part number stamped on the valve
with that published in approved service literature or in
the installation drawing.
