Reduces System Space
Requirements
Sandwich valves make com-
pact hydraulic systems in which
specific function valves are
“sandwich” mounted between
a directional valve and a
standard mounting surface.
Reduce Cost
Sandwich valves eliminate inter
valve piping and leak-prone
tube and pipe connections.
Installed cost is less than when
using conventional valves.
Versatile and Easy to Install
Sandwich valves have all the
internal passages necessary to
serve the directional valve top-
ping them. Mounting surfaces
and port patterns are to inter-
national standards: any valve
conforming to ISO 4401 size
03; ANSI/B93.7M size D03;
NFPA-D03; CETOP 3; and
DIN 24340, NG6 mounting
interface can be used with
these Sandwich valves.
Linking and blanking plates are
available to facilitate a variety of
circuit designs and flexibility in
applying these valves.
Rugged and Reliable
Cartridges are produced from
hardened steel and mounted in
aluminum housings. Excellent
reliability is ensured. Cartridges
are accessible without remov-
ing valves from an assembled
stack. The housings are
assembled in a kit
containing a locating pin for
error free installation, all neces-
sary plugs and
standard Viton seals.
Sandwich Systems... Easy to
Understand, Easy to Design
Sandwich circuitry is best
shown using slightly
different symbols than those
for traditional valve configura-
tions. Each Sandwich symbol
has the same basic form and
size as shown in figure 1.
For ease of understanding,
remember the directions of
flow for each line, and that all
four flow paths pass through
each valve (see figure 2).
For clarity, directional valves are
drawn vertically in Sandwich
circuit diagrams (see figure 3).
Each station (valve stack) is
a combination of functions.
When designing and assem-
bling Sandwich valves, care
must be taken to ensure that
they interact as required by
stacking the functions in the
correct sequence (figure 4 is an
example).
Relief valves should normally
be positioned next to the
mounting surface (i.e. at the
bottom of the stack). When
both a flow control and a
pilot operated check valve are
required, it is recommended
that the flow control valve be
between the check valve and
the actuator to prevent check
valve chatter.
A combination of directional
valve, sandwich valve(s) and
subplate/manifold block com-
pletes the assembly.
Sandwich Valve Assemblies
Aluminum sandwich valve
assemblies consist of a hous-
ing kit, and one or more car-
tridges. They can be purchased
complete by specifying a sand-
wich model code or built by
mixing an appropriate housing
kit with cartridges to attain a
desired function.
A housing kit contains a hous-
ing, locating pin, all necessary
plugs and
standard Viton seals.
Sandwich Valve Locators
Sandwich valve locators group
products by function and pro-
vides an easy way to identify a
specific sandwich valve in the
catalog.
It presents a sandwich valve
functional symbol, function
description and basic model
code. Since every sandwich is
put together by inserting
cartridges into a housing kit,
the locator provides concise
information for easy selection
of the components to build a
specific function.
The following information is
shown in the locator for every
function: Housing kit model,
part number, catalog page with
the detailed information for the
housing kit, model code and
the catalog number for the car-
tridges & cartridge cavity.
Housing Kits Data Page

Ordering Information
To order sandwich valve com-
ponents, use the information
in the sandwich valves locator
pages L-6 thru L-19.
To order a sandwich valve
complete for models with one
cartridge:
• Selectthemodelcodefrom
the sandwich valve locator.
Note that the housing kit
model code substitutes for
the standard inline body
code in the same model
field.
• Gotothereferenced
cartridge valve literature to
complete the balance of the
sandwich model code.
To order a sandwich valve
complete for models with two
cartridges:
• Selectthemodelcodefrom
the sandwich valves locator.
• Gotothereferencedpage
for the model code

Sandwich Valve
Model Codes
In order to speed the release
of new products to customers,
the sandwich valve product
line has been configured with
a fixed length model code. A
fixed length model code simpli-
fies the ordering process for our
customers and facilitates the
automated production release
of new valves and settings. In
general, we have followed the
standard model code for the
base valve with the following
three exceptions:
1. Seals: When specifying
Buna-N seals, an N should be
used in the model code for
sandwich valves. (In the stan-
dard valve model code Buna-N
seals are specified by leaving
this column blank.)
2. Pressure settings: To avoid
confusion on pressure settings,
the setting should always be
specified and not left blank. In
addition, the confusing decimal
system has been eliminated
for sandwich valves. In the
sandwich valve model code,
simply specify the entire pres-
sure setting in PSI using four
digits for relief valves and 3
digits for check valves. Include
leading zeros if necessary. For
example:
Relief and Counterbalance
Valves
500 psi – 0500
50 psi – 0050
1525 psi – 1525
Check Valves
210 psi – 210
20 psi - 020
3 psi - 003

if where required.)

Spare Parts
For Sandwich Valve Assemblies
Accessory Plates
& Stud Rods
Accessory Plates
Linking and blanking plates are
available to facilitate a
variety of circuit designs and
flexibility in applying these
valves. All accessory plates
come with Viton O-Rings.
Stud Rods
To simplify the installation of
the sandwich valves, stud rod
& nuts kits can be ordered and
cut to length in the field. Once
the rods are installed, they act
as a guide when assembling
the sandwich valves stack. After
assembling the directional con-
trol valve on top of the stack,
special nuts are used to retain
the stack. Eaton offers 178 mm
(7 in) or 305 mm (12 in) bolt kits
(one bolt kit for these Sandwich
valves comprises 4 bolts). To
determine your needs, use the
following guide for bolt length
calculation.
