RANGE OF ORIFICE SIZE
The control covers LD-CCE of the H6 series are available with standard orifice. These types ensure the basic
functionality of the comination with cover and cartridge valve and should be used if the application is not known or
defined yet.
The final adjustment of the orifice diameter to optimise switching time and/or damping performance is the
responsibility of the user or is only possible during application.

General directional function
For a directional function, logic valves with poppet B, C, E or F are fundamentally suitable.
Furthermore, a cover is necessary to control the forces acting on the poppet.
The pressure acting on port A and B results to an opening force. The pressure in the spring chamber results to a
closing force. The valve is closed due to the sring force if there is only a small pressure or no pressure.
You can see the 1D cover in the example. The pressure acts on the poppet via the port X causing the closing gof the
valve. If X is connected to the tank, only the spring force remains to close the valve.

General pressure function
Typical applications for a pressure relief function in cylinder and pumps.
For a pressure function, logic valves with poppet A and EX are fundamentally suitable. The special feature of these
types is a minimal area ratio or no area ratio between port A and B. This leaves only two control areas (A and C).
The limited pressure is on port A, but is also channelled to port C of the cover at the same time. If the pressure in port
A exceeds the value of the current pressure setting of pilot valve in port C, the valve opens.

DIRECTIONAL VALVE FUNCTION ¹
If a 1D cover is used in combination with a 2-way cartridge valve, the
pressure at cover port X relieves to the tank by realising a 2-way function –
flow direction from A B or B A.
The highest system pressure or the highest pressure from A or B on port X of
the cover results a blocking of the flow from A to B – and conversely.
CHECK FUNCTION ¹
If a 1D cover is used in combination with a 2-way cartridge valve, a check
function can be realised by connecting control port X to port B - flow direction
A B (B A blocked).

Standard models
The 1D cover is equipped with a single orifice in X, which can be accessed from the outside. This orifice is used to limit
the flow from and to the C port of the cover and thus limit the opening and closing rate of the logic valve. For support
with orifice configuration, please contact HYDAC Fluidtechnik GmbH.

FUNCTION
Control cover in combination with a 2-way cartridge valve for directional and
check functions – depending on port X
Control cover with remote control port to ISO 7368
Orifice can be installed at port X
Adjustable stroke limitation (throttle function)
The control cover 1H can be combined with 2-way cartridge valves with
poppet B, C, E and F.
DIRECTIONAL VALVE FUNCTION ¹
If a 1H cover is used in combination with a 2-way cartridge valve, the
pressure at cover port X relieves to the tank by realising a 2-way function –
flow direction from A B or B A.
The highest system pressure or the highest pressure from A or B on port X of
the cover results a blocking of the flow in both directions.
THROTTLE FUNCTION ¹
The adjustable stroke limitation throttles the flow in both directions.
Adjustment of the stroke limitation is only partially possible under pressure.
The stroke limitation could also cause the 2-way cartridge valve to close – but
this is not the standard function.
CHECK FUNCTION ¹
If port X of the 1H cover is connected to port B of the logic, a check function
is realised. There is flow from A to B, but it is blocked in the opposite
direction.
Hint
The 1H cover is incompatible with the following 2-way cartridge valves and
must not be used with them: poppet A.
Other cartridge types, e.g. other cartridge series (D) or cartridge valves from
other suppliers are not compatible with the 1H cover.

FUNCTION
Control cover with remote control port to ISO 7368
Orifice can be installed at port P, A, B, T
Pilot port interface size 6 and 10 (size 6 pilot valves can be used up to
control cover size 50, and size 10 pilot valves for control covers size 63 and
above)
Depending on the function, control cover RM can be combined with the
following 2-way cartridge valves:
- Pilot-operated directional function:
2-way cartridge valves with poppet B, C, E and F.
- Pilot-operated pressure relief function:
2-way cartridge valve with valve poppet A or E.
DIRECTIONAL VALVE FUNCTION ¹
If an RM cover is used in combination with a 2-way cartridge valve and a 4/2-
way pilot valve, a 2-way function is realised ich the solenoid is energized and
a plug is in port B of the cover - with flow direction A B or B A. This is
achieved by pressure release of the spring chamber of 2-way cartridge valve.
If the solenoid is not energized and a plug is in port B of the cover, the
pilot pressure is applied to the spring chamber at port X. Depending on the
pilot pressure, the corresponding flows are blocked. If the plug is installed in
port A of the cover, the function for energized and de-energized solenoids is
precisely the opposite.
PRESSURE RELIEF FUNCTION ¹
If an RM cover is used with a 2-way cartridge valve and a pilot pressure relief
valve, a pressure relief function can be realised.

DIRECTIONAL VALVE FUNCTION ¹
If a 1W cover is used in combination with a 2-way cartridge valve and a pilot
valve, the same function is realised as RM cover.
If the solenoid of the directional valve is energized, the spring chamber of the
cartridge valve is connected to the tank. This enables flow from port A to B,
and conversely.
If the solenoid is de-energized, the spring chmaber is supplied with pilot
pressure from port X.
If this pilot pressure comes from port A of the cartridge valve, flow from A
B is blocked; if it comes from port B, it is blocked in the opposite direction.
Furthermore, port Z1 and Z2 can be used to actuate another 2-way cartridge
valve.

Control cover with integrated dhuttle valve
Control cover with remote control port to ISO 7368

covers size 63 and above)
The control cover 2W can be combined with 2-way cartridge valves with
poppet B, C, E and F.
CHECK FUNCTION ¹
2W cover with a 4/2-way pilot valve results in a pilot operated check function.
As long as no port Z2 is not relieved - flow from port B A is constantly
blocked.
The flow direction A – B can be influenced by the switching position of the
pilot directional valve. If there is a plug in B, flow A to B is open if the solenoid
is energized; if the solenoid is de-energized, A to B is blocked.
If there is a plug in port A, the pilot function is conversely.
Depressurising Z2 opens flow from A to B on both sides.
Additionally, Z2 can be used to actuate other valves.

FUNCTION
Control cover with parallel check valves at port X and Z1
The higher pressure of both is at port P
This feature is useful in applications where the risk of the 2-way
cartridge valve briefly opening during the pilot pressure change needs
to be fully eliminated.
Control cover with remote control port to ISO 7368
Orifice can be installed at port P, A, B, T, C, Z2
Pilot port interface size 6 and 10 (size 6 4/2-way pilot valves can be used
up to control cover size 50, and size 10 4/2-way pilot valves for control
covers size 63 and above)
The control cover 4W can be combined with 2-way cartridge valves with
poppet B, C, E and F.
DIRECTIONAL VALVE FUNCTION ¹
If a 4W cover is used in combination with a 2-way cartridge valve and a pilot
valve, a bidirectional directional function or a check function can be realised.
If the solenoid is energized and a plug is installed in port B of the cover, the
spring chamber of the cartridge valve is connected to the tank. This enables
flow via 2-way cartridge valve in both directions.
If the solenoid is de-energized, the higher of the two pilot pressures is at port
X and Z1 in the spring chamber. This enables a check function - depending
on location decrease of pilot pressure at port A or B in the corresponding
direction:
If the pilot pressure of port A is reduced, flow from A to B is blocked.
If the pilot pressure of port B is reduced, flow from B to A is blocked.
Precisely the opposite functions are achieved in terms of a switching valve,
which is on and off if a plug is installed in port A instead of port B.
Furthermore, port Z2 can be used to actuate a second 2-way cartridge valve.

The control cover 1WDB can be combined with 2-way cartridge valves with
poppet A and EX.
PILOT OPERATED PRESSURE RELIEF FUNCTION ¹
When using a 1WDB cover in combination with a 2-way cartridge valve, two
pressure relief valves in sandwich plate design and a directional control valve
as pilot valve, a pilot operated pressure relief function can be realized.
Due to a two-stage pressure relief function, it is possible to work with two
preset pressures.
When the directional valve is energized, port P is connected to port A. The
pressure in port X is passed to the pilot valve (2) via port A on the directional
control valve, acting on both pilot valves. The lower pressure setting opens
the pilot valve (2). After overcoming the spring force, the cartridge valve
opens from port A to port B. If the directional valve is not energized, the pilot
valve (2) is switched to the low-pressure side. This limits the pressure at the
pilot valve (1) and the cartridge valve opens.

PRESSURE RELIEF FUNCTION ¹
When using a DRE cover in combination with a 2-way pressure cartridge
valve, a pressure relief valve and a directional valve, a pressure relief
function can be realized.
When the directional valve is energized, port P is connected to A. The
cartridge valve opens when the pressure is higher than the pressure setting
on the pressure relief valve. The spring chamber is relieved by the orifice in
port A.
If the directional valve is de-energized, a pressureless circulation from port A
to port B of the cartridge valve results and the oil flows to the tank after
overcoming the spring force.
