INTRODUCTION
Cartridge Covers
PRODUCTPRODUCT OOVERVERVIEWVIEW
The $artridge Valve Covers featured in this catalog are
designed for PVS 2-way Slip-in Cartridge Valves (CEE
series). These valves offer the highest nominal flows and
lowest pressure drops available on the market (see
cartridge catalog for more details). Additionally, the
covers can also be used with most PGPVS Slip-in Cartridge
Valves (CKE, CEHFE and previous CEE series) which are
designed according to ISO 7368.
The rated pressure of the covers is up to 420 bar (6,000 psi),
depending on cover type and seal material. State-of-the-art
development techniques were used to optimize the cover
design for this rated pressure. This results in reliable
performance in even the most extreme load applications.
The cover series offers a variety of directional, flow and
pressure control functions. Due to the integration of
check and shuttle valves as well as interfaces for subplate
pilot valves, a compact system design even for complex
functions can be achieved.
13 different cover types are available for the nominal
diameters (sizes) 16, 25, 32, 40, 50, 63, 80, 100, 125 and
160 mm according to ISO 7368. Each cover type can be
equipped with different seals for use with a wide variety
of operating fluids.

INTRODUCTION
DESCRIPTION OF OPERATIONDESCRIPTION OF OPERATION
Operating Principle for Directional Function
In order to successfully create a directional function for
an application, it is important to understand the basic
operating principles of a directional cartridge valve in
combination with a cartridge cover.
A directional function requires, first of all, a cartridge
valve with a B, C, E or F poppet (6). These poppets all
have a stepped shape resulting in 3 different control
surfaces; a control surface for the A (7), B (5) and C (2)
ports.
Second, a cartridge cover (1) is necessary to control the
sum of the forces applied to each of these control
surfaces. Pressure applied to the surfaces at A and B will
work to open the valve; pressure applied to the surface
at C will work to close the valve. Should little or no
pressure be present, the force of the spring (3) will hold
the valve closed.
In the example of the 1D cover shown, the X port supplies
the pressure working to close the valve. If X is connected
to the tank, there is only the spring force remaining to
close the valve. This results in a bi-directional function
where the flow direction is A ĺ B or B ĺ A.
If the X port is connected to the A or B port of the
cartridge valve, then the pressure in X will close the valve
and the flow from A ĺ B or B ĺ A respectively will be
blocked.

INTRODUCTION
DESCRIPTION OF OPERATIONDESCRIPTION OF OPERATION
Operating Principle for Pressure Function
Pressure relief valves and covers are vital components of
any hydraulic system. Together, these components are
used to limit the maximum permissible hydraulic pressure
where necessary.
Typical applications include limiting pump and cylinder
pressures. The limiting of cylinder pressures not only
protects the cylinder from damage, but also enables the
reliable control of the force applied by the cylinder.
In combination with a cover and a pilot valve, both manual
and electrical proportional pressure settings can be
realized with or without relief functionality. In order to get
the most out of these functions, it is important to
understand the basic operating principles of a pressure
cartridge and cover.
The A0 and EX poppets used in pressure functions have no
or only a small control surface at port B. Leaving only 2
primary control surfaces, surface A working to open the
valve, and surface X together with the spring force
working to close the valve.
The pressure to be limited is applied to port A (8), and is
also routed simultaneously to port C (3) of the cover (2)
and the pilot valve (1) via a pilot line (10) equipped with a
suitable metering orifice. If the pressure in port A exceeds
the present pressure setting of the pilot valve, the pilot
valve opens venting the pressure at port C. The pressure
compensated poppet (7) then opens against the spring
force (4) and set pressure, limiting the pressure at port A.
When ordering components for a pressure function, it is
important to note that it is also possible to enhance the
functionality of a cover (e.g., a depressurizing function or
additional pressure stages) by using additional sandwich
plate valves.
For pressure reducing and compensating functions XF
offer the DMO series of 2-way Slip-in Cartridge Valves
with a spool design. Please refer to the catalog for more
information.

1)
to create both check and directional functions;
depending on how the X port of the cover is connected.
Directional Function
If the X port of the cover is connected to tank, then flow
is enabled in both directions from A ĺ B and B ĺ A.
Whereas, if the X port is connected to sufficient pilot
pressure, flow will be blocked in both directions.
Check Function
If the X port of the cover is connected to the B port of the
cartridge, a check function is created with the flow
direction being only A ĺ B. The flow in the other
direction, B ĺ A is blocked.

TECHNICAL DATA
RRM M CCOOVERVER
Functional Description
The
RM cover is a versatile cover that can be used for
both pressure and directional functions depending on the
type of pilot valve used.
Pilot-Operated Directional Function
When using an RM cover in combination with a cartridge
1)
and a control valve
2)
, a bi-directional function or a check
function can be achieved depending on the state of the
solenoid.
When the solenoid is energized, and there is a plug in port
B of the cover, then the spring chamber of the cartridge is
connected to tank. This enables flow over the cartridge in
both directions: from A ĺ B and from B ĺ A.
When the solenoid is de-energized, then the spring
chamber is subject to the pilot pressure from control port
X of the cover. For example, if this pilot pressure is drawn
from the A side of the cartridge, then flow from A to B is
blocked; and vice versa when the pilot pressure is drawn
from B.
Normally Closed vs. Normally Open
The above configuration can also be regarded as
“Normally Closed”. When the solenoid is de-energized, the
pilot pressure from X will hold the cartridge valve in the
closed position.
A “Normally Open” function can be achieved by moving the
plug from Port B to Port A. This will allow the cartridge
pilot oil to vent to tank, leaving only the cartridge spring
force to maintain the cracking pressure.
1) Cartridge with a B, C, E or F poppet.
2) Control valve: An ISO 4401, size 03 directional control valve
for cover sizes up to 50 or an ISO 4401, size 05 directional
control valve for cover sizes 63 to 100.

Functional Description
The DRE cover is a versatile cover that is used primarily
for more complex pressure functions requiring multiple
pilot valves.
Pressure Relief and Soft Unloading Function
When using a DRE cover in combination with a pressure
cartridge
1)
, a pressure relief valve
2)
and a "99&30/
):%30-69 soft unloading control valve
3)
; a pressure
relief function or a soft unloading function can be
achieved depending upon the state of the solenoid.
When the solenoid is energized, a pressure relief function
is created as the pressure from the X port of the DRE
cover holds the cartridge closed with a pressure
determined by the relief valve.
When the solenoid is de-energized, a very soft and
pressure independent unloading function is achieved.
When the solenoid is re-energized, the cartridge closes at
full speed.
An AO or EX poppet.
For example, a direct-operated pressure relief valve.

11WW CCOORVEVER
Functional Description
The 1W cover is a versatile cover that can be used for
both pressure and directional functions depending on the
type of pilot valve used.
Pilot-Operated Directional Function
When using a 1W cover in combination with a cartridge
1)
and a control valve
2)
, a bi-directional function or a check
function can be achieved depending on the state of the
solenoid.
When the solenoid is energized, the spring chamber of the
cartridge is connected to tank. This enables flow over the
cartridge in both directions: From A ĺ B and from B ĺ A.
When the solenoid is de-energized, the spring chamber is
subject to the pilot pressure from control port X of the
cover. For example, if this pilot pressure is drawn from
the
A side of the cartridge, then flow from A to B is
blocked; and vice versa when the pilot pressure is drawn
from B.
The Z1 or Z2 port can be used in order to activate another
cartridge
1)
.
Pressure Reducing Function
2-way pressure reducing valves are used to reduce a
variable input pressure (primary pressure at B) to a lower,
constant output pressure (secondary pressure at A).
The reduced pressure can be set using a pressure relief
valve on the valve cover. Depending on configuration, this
valve can also function as a pressure compensator.
The valves are available as “normally open” or “normally
closed” versions. For more detailed information please
refer to the pressure reducing valve (DMO series)
catalog.
1) Cartridge with a B, C, E or F poppet.
2) Control valve: An ISO 4401 size 03 directional control valve
for cover sizes up to 50 or an ISO 4401 size 05 directional
control valve for cover sizes 63 to 100.

TECHNICAL DATA
11WDWDB B CCOOVERVER
Functional Description
The
1WDB cover is a versatile cover that is used primarily
for more complex pressure functions requiring multiple
pilot valves.
Pilot-Operated Pressure Relief Function
A two stage pressure relief function is capable of
operating at two different preset pressures depending on
the state of the solenoid valve. For this function a 1WDB
cover in combination with a cartridge
1)
, two pressure relief
sandwich valves
2)
and a directional pilot valve
3)
are needed.
When the solenoid is energized, the pressure in the X port
of the cover is connected to the secondary pressure relief
pilot valve by means of the A port on the solenoid valve.
This secondary pilot valve, with a lower pressure relief
setting, will override the higher pressure setting of the
main pressure relief pilot valve.
When the solenoid is de-energized, the secondary
pressure relief valve is no longer part of the circuit. This
leaves only the main pressure relief valve with the higher
pressure relief setting as active.
1) An AO or EX poppet.
2) For example, a direct-operated pressure relief valve.
3) Control valve: An ISO 4401 size 03 directional control valve
for cover sizes up to 50 or an ISO 4401 size 05 directional
control valve for cover sizes 63 to 100.

Functional Description
The
2D cover contains an integrated shuttle valve
designed to allow only the highest of the available pilot
pressures to continue to the C port. Depending on how the
pilot ports are connected, the 2D can be used in
combination with a cartridge
1)
to create both check and
directional functions.
Directional Function
If the X and Y ports of the cover are connected to tank,
then flow is enabled in both directions from A ĺ B and
B ĺ A. If one or both of the X and Y ports are pressurised,
then the highest of both pressures is acting to close the
cartridge.
Check Function
If the X or Y port is connected to the A port of the
cartridge, a check function is created, blocking the flow
from A ĺ
B. Likewise, if the X or Y port is connected to
the B port, flow will be blocked in the opposite direction,
from B ĺ A.

22WW CCOOVERVER
Functional Description
The 2W cover contains an integrated shuttle valve
designed to allow only the highest of the available pilot
pressures to continue to the C port. In contrast to the 2D
cover, the 2W cover is equipped with a port pattern. This
additional port pattern enables more complex functions to
be created by using a pilot valve.
Pilot-Operated Check Function
The 2W cover can be used in combination with a cartridge
1)
and a control valve
2)
to create a check function that can be
enabled depending upon the state of the solenoid.
When the solenoid is energized, the flow direction is
A ĺ B only. This is due to the plug in the B port of the 2W
cover blocking the pilot pressure from the A port of the
cartridge. The remaining pilot pressure connected to the B
port of the cartridge blocks the flow direction B ĺ A.
When the solenoid is de-energized the flow in both
directions, from B ĺ A and A ĺ B, is blocked.
If the plug is installed in port A of the cover, the function is
exactly the opposite with regard to an energized and de-
energized solenoid. In other words, the flow in both
directions will be blocked when the solenoid is energized.
When the solenoid is de-energized, flow will only be
permitted in the direction A ĺ B.
Finally, the Z2 port may be used in combination with an
additional control valve
2)
to unlock the check function
from B ĺ A by connecting the spring chamber of the
cartridge to tank. This will enable flow through the
cartridge in both directions. Or, the Z2 port can also be
used to activate a second cartridge valve.
1) Cartridge with a B, C, E or F poppet.
2) Control valve: An ISO 4401 size 03 directional control valve
for cover sizes up to 50 or an ISO 4401 size 05 directional
control valve for cover sizes 63 to 100.

22WRWR CCOOVERVER
Functional Description
The
2WR cover contains an integrated shuttle valve
designed to allow only the highest of the available pilot
pressures to continue to the C port. In contrast to the 2W
cover, the 2WR cover uses only the X and the A ports to
control the integrated shuttle valve. Ports B and Z2 can be
used for other control functions.
Pilot-Operated Check Function
The 2WR can be used in combination with a cartridge
1)
and
a control valve
2)
to create a check function that can be
enabled depending upon the state of the solenoid.
When the solenoid is energized, the flow direction is A ĺ
B only. This is due to the directional valve routing the pilot
pressure from the A port of the cartridge away from the
spring chamber and towards the Z2 port. If, however, the
pressure in port B exceeds the one in port A, it closes the
cartridge and blocks the flow direction B ĺ A.
When the solenoid is de-energized the flow in both
directions, from B ĺ A and A ĺ B, is blocked.
Finally, Uhe Z2 port may be used to activate another
cartridge
1)
.
1) Cartridge with a B, C, E or F poppet.
2) Control valve: An ISO 4401 size 03 directional control valve
for cover sizes up to 50 or an ISO 4401 size 05 directional
control valve for cover sizes 63 to 100.

TECHNICAL DATA
44WW CCOOVERVER
Functional Description
The
4W cover offers parallel check functions on the X and
Z1 ports. The larger pressure of the two is then applied to
the P port. This feature is helpful in applications where the
risk of a short-term opening of the cartridge
1)
during pilot
pressure switching must be positively prevented.
Directional Function
When using a 4W cover in combination with a cartridge
1)
and a control valve
2)
, a bi-directional function or a check
function can be achieved depending on the state of the
solenoid.
When the solenoid is energized, and there is a plug in port
B of the cover, then the spring chamber of the cartridge is
connected to tank. This enables flow over the cartridge in
both directions: From A ĺ B and from B ĺ A.
When the solenoid is de-energized the spring chamber is
subject to the larger of the pilot pressures from the X and
Z1 ports creating a check function.*GUIFQJMPUQSFTTVSFJT

GSPNQPSU#UIFGMPXGSPN#UP"JTCMPDLFE
If the plug in the 4W cover is installed in port A instead of
port B, then the functions with respect to an energized and
a de-energized solenoid are reversed.
Finally, the Z2 port may be used to activate another
cartridge

Functional Description
The RV cover contains an integrated shuttle valve with the
possibility of an override.
Pilot-Operated Check Function
When using a RV cover in combination with a cartridge
1)
, a
check function is achieved by connecting the Z2 port with
port B of the cartridge valve. The flow direction is A ĺ B
(B ĺ A blocked).
An override of the check function is possible if the X port
is subject to pressure. This will cause the shuttle valve to
open towards the Y port and drain the spring chamber of
the cartridge to tank. For the override to function, the
pilot pressure at port X must be at least 20 % (1:5) of the
load pressure in port B.

DBA COVER
Functional Description
A DBA cover uses an integrated pressure relief valve to
create simple pilot operated pressure relief functions.
Pilot operated pressure relief function
A more detailed description of how a pilot operated
pressure relief valve works can be found in the
description of operation on page 6. Additionally,
complete pressure relief valve configurations (cartridge
valve plus cover) can be found in our %#7.13&4463&
3&-*&'7"-7&4DBUBMPH.
Orifice Configuration
In order to get the maximum performance out of a DBA
cover, it is important to select the right orifice
combination. Failing to do this may result in poor valve
performance.
The preferred standard orifice configurations provided
here assume the use of an A poppet and the pressure
range desired. Not included are configurations using EX
poppets or with tamper proof seals on the pressure
settings. For more assistance regarding orifice
configurations please contact VT.

TECHNICAL DATA
DDBBDD CCOOVERVER
Functional Description
A DBD cover is a versatile cover with an integrated
pressure relief valve that is used primarily for more
complex pressure functions requiring multiple pilot valves.
Pressure Relief with Unloading Function
When using a DBD cover in combination with a pressure
cartridge
1)
, and a directional pilot valve
2)
; a pressure relief
function or an unloading function can be achieved
depending upon the state of the solenoid.
When the solenoid is de-energized, a pressure relief
function is created as the pressure from the X port of the
DBD cover holds the cartridge closed with a pressure
determined by the relief valve.
When the solenoid is energized, the relief valve is
bypassed and the pressure in the system is unloaded
as the pilot volume of the cartridge is drained to tank and
the cartridge opens.
1) An AO or EX poppet.
2) Control valve: An ISO 4401 size 03 directional control valve
for cover sizes up to 50 or an ISO 4401 size 05 directional
control valve for cover sizes 63 to 100.

BACKGROUND
SELECTION OF ORIFICE SIZESELECTION OF ORIFICE SIZE
This calculation is used to select the orifice size which
influences the opening and closing times. It may be
necessary to optimize the settings on the machine. Using
the diagram below, the cartridge opening and closing times
may be calculated for various orifice sizes.
Equation:
Opening and closing time [ms] =
Pilot oil volume cartridge [cm
3
] x 60
Orifice flow (diagram) [l/min]
The pilot oil volume can be read from the applicable
cartridge catalog.
Example:
To determine the closing time of a size 25 cartridge with
a B poppet, it is necessary to know the orifice size and the
ǻp across the orifice. Using the equation shown an orifice
of 0.8mm in diameter and a ǻp of 90 bar across the orifice
will result in a closing time of 184 ms.
Opening and closing time [ms] = = 184 ms
