The Bosch Rexroth LC2A025A40D-1X/XQ7G24F (R901335062) is an advanced, actively controllable two-level active logic cartridge valve designed for precise hydraulic control. This model features a compact modular design, allowing for flexible integration into various circuit setups. The core components of this valve include a cartridge control spool and socket, an intermediate cover, and a control cover type LFA which facilitates the connection with pilot control valves and other hydraulic elements.
The LC2A025A40D-1X/XQ7G24F valve is distinguished by its differential spool with an additional control area A, enhancing its functionality by allowing it to open and remain open through pilot pressure independently of the main ports A or B pressure. The spring chamber area encompasses individual areas A1, A2, and A3 that are effective in the opening direction while area A4 and the spring force act in the closing direction. This configuration provides benefits in terms of closing force and velocity.
This model ensures leakage-free operation due to its spool sealing, guaranteeing a hydraulically tight seat area. It can be directly installed into a standard installation bore conforming to ISO specifications, making it suitable for retrofitting existing passive logics systems that require internal leak-proof performance or position monitoring.
The LC2A025A40D-1X/XQ7G24F also offers optional position switch integration for monitoring the closed position of the valve poppet. The switch can be retrofitted at any time without adjustments as the receiving hole is provided as standard.
In summary, this Bosch Rexroth directional cartridge valve boasts energy efficiency due to its flow-optimized geometry and is certified by BG standards. It supports maximum operating pressures up to bar and maximum flow rates measured in liters per minute (l/min), ensuring robust performance across a wide range of hydraulic applications.

General
The 2-way cartridge valves type LC2A (hereinafter referredto as "active logics" (2) are designed in compact modular design and basically consist of cartridge (control spool (3) and socket (4), intermediate cover (5) as fixed functional unit and a control cover type LFA (1) that is part of the Rexroth standard logics program. This control cover (separate order, see data sheet 21010 or 21050) establishes the connection with the pilot control valves and/or other hydraulic elements and thus integrates the most different functions - irrespective of the basic assembly. Virtually all standard and special control covers type LFA can be mounted. Optionally, the active logics (2) is available with position switch (6). By default, the "closed" position of the control spool (3) is recorded. The receiving hole for the position switch is provided as a standard. This means that the position switch "Q7" can be retrofitted at any time without requiring adjustments. In contrast to the logic assemblies with only one control area in the spring chamber ("passive logics"), the name "active logics" significantly stands for a version with differential spool, with at least one additional control area A4 ("two-level active logics"). This area allows for the opening and keeping open of the active logics (2) by means of pilot pressure (without the necessity of pressure in the main ports A or B). The spring chamber area A5 of the control spool (3) consists of the individual areas A1 + A2 + A4. Compared to passive logics without control area A4, this results in excess area which, with suitable hydraulic circuitry, offers advantages during closing and keeping closed (excessive force, closing velocity).
In general
Area total A5 = A1 + A2 +A4 = A3 + A4 The areas A1, A2 and A4 are effective in the opening direction, area A5 (and the spring force) in closing direction. So the resulting effective force determines the position and movement of the control spool (3). Usually, there are no interim positions in the directional function variants. The direction of flow is free and can thus be perfectly adjusted to the application. Active logics type LC2A are generally equipped with spool sealing and are therefore leakage-free inside. The seat area is hydraulically "tight".
Active logics for directional function
Depending on the task, different control spool versions are possible. The active area can be connected with the available pilot oil guides in almost any way and in this way, most different functions can be realized with only 1 basic assembly.
Installation bore
The active logics type LC2A can be directly installed in a standard installation bore according to ISO 7368 (see dimensions). Thus, it is also suitable as retrofitting for existing "passive logics" that must be leakage-free inside or require position monitoring or faster closing times.

Depending on the "Active area" ordering code, the number of possible orifice fittings is different in the continuous pilot oil guides, see "Orifice assignments" below.

The fitting and assignment of the "active area" is not shown here (see "Assignment of the active area")
For details on the dimensions of the orifice installation bores "X" to "L", see "Dimensions".
On the component side, the orifice installation bores are always completely available; on the plate side, only the combinations of versions "H" and "L" or "D" and "S" are possible, see "Ordering code".
Notice:
With control channels that are not required, you must either use a blanking plug ".99" or the corresponding cover.
Circuit examples (schematic diagram, function must be checked with the application)
Notice:
It has to be ensured that pilot oil ports that are not required (blanking plugs) and all pressurized transitions between LFA and LC2A (R-rings) are sealed. This is particularly true for variants marked with *.

Control spool remains open as long as FZ2 ≥ FA + 30 bar
In case of failure or drop of the pilot pressure, the logic element closes hydraulically. Irrespective thereof, the logic element can be opened by unloading the spring chamber (minimum pilot pressure required).
"Pulling" and "Safe keeping closed" function
| 1) | Consumer |
The control spool of the active logics can be opened or closed depending on the two pilot oil pressures X and Z2. Thus, free flow is possible in both directions, irrespective of the pressure level in port B.

Notice!
The length of the valve mounting screws of the active logics (intermediate cover) must be selected according to the related control cover type LFA....
Screw type, screw length and tightening torque are to be adjusted to the conditions depending on the application.
For reasons of stability, exclusively the following valve mounting screws may be used:
Installation bore and connection dimensions according to ISO 7368
Dimensions in mm
|
|
Required surface quality of the valve contact surface |
|

Depth of fit |
|
2 |
Port B may be positioned around the central axis of port A. However, it must be observed that the mounting bores and the pilot oil bores are not damaged. |

| 1) | Due to the use of a bore with ØD3*, port B protrudes over the upper limit of the area intended in ISO 7368. This is, however, possible due to the sealing concept and reduces the pressure loss during flow through the valve. Thus, we recommend a bore with ØD3*. |
