***Disclaimer: The following summary contains information gathered from various sources such as product descriptions, technical specifications and catalogs. While efforts have been made to provide accurate details, inaccuracies may occur. It is advised to verify all information by contacting Bosch Rexroth directly.***
The Bosch Rexroth LC16A05D7X/V (R900925950) is a high-performance industrial hydraulic valve designed for efficient and reliable switching of oil flow directions. This bidirectional, hydraulically actuated spool type AD valve is part of the standard series with component series X, X, and X. It boasts a maximum operating pressure of bar and can accommodate a maximum flow of l/min. The LC16A05D7X/V features a cartridge valve design optimal for compact block integration, adhering to ISO standards for ease of installation.
Equipped with FKM seals, this valve is compatible with various hydraulic fluids such as HL, HLP, HLPD, HVLP, HVLPD, HETG, HEES, HEPG, HFDU, and HFDR. The control cover includes control bores and can optionally come with stroke limitation function or other hydraulic control elements like directional seat valves or shuttle valves depending on the overall required function. The installation kit comprises essential components such as bushing and ring (up to NG), valve poppet (with or without damping nose), and closing spring.
The functionality of the LC16A05D7X/V valve is pressure-dependent with three pressurized areas (A1, A2, A3) that contribute to its operation. With varying area ratios such as . : 1 or 1 : 1 between A1 : A2 and different annulus areas A2, this enables diverse cracking pressures to be achieved. The spool position is determined by the direction of the resultant force from opening and closing forces acting on areas A1 and A3 respectively along with the spring mechanism.
This versatile way cartridge valve permits fluid flow from port A to B or vice versa when piloted correctly. It ensures that channel A remains blocked without leakage when area A3 is pressurized through pilot oil discharge from channel B or through an external pilot oil supply. The LC16A05D7X/V model code represents Bosch Rexroth's commitment to providing robust solutions for hydraulic system needs across various applications requiring precise flow control.

2-way cartridge valves are elements that have been designed for a compact block design. The power section with connections A and B is installed into the control block in a receiving hole standardized according to ISO 7368 and closed with a cover. In most cases, the cover is also the connection from the control side of the power section to the pilot control valves.
By control with respective pilot control valves, the power section can be applied for pressure, directional and throttle functions or a combination of these functions. Particularly efficient solutions are realized by adjustment of the size to various flows of the individual ways of an actuator. The application of power sections of elements for multiple functions is very cost-effective.
2-way cartridge valves generally consist of control cover (1) and installation kit (2). The control cover contains the control bores and optionally a stroke limitation function, a hydraulically controlled directional seat valve or a shuttle valve according to the required overall function. Additionally, electrically operated directional spool or seat valves can be installed at a control cover. The installation kit consists of a bushing (3), ring (4) (only up to NG32), valve poppet (5), optionally with damping nose (6) or without damping nose (7) as well as closing spring (8).
The function of 2-way cartridge valves is pressure-dependent. This way, three crucial pressurized areas are realized for the function. A1, A2, A3. The area at valve seat A1 is observed as 100 %. Depending on the version, the annulus area A2 realized by grading is 7 % or 50 % of area A1. The area ratio A1 : A2 is respectively either 14.3 : 1 or 2 : 1. The area A3 is identical to the sum of areas A1 + A2. Due to the different area ratios A1 : A2 and the resulting different annulus areas (A2), the area A3 is one time 107 % and another time 150 % of the area A1 at the seat, which is observed as 100 %.
In general, the following applies:
The areas A1 and A2 are effective in opening direction. The area A3 and the spring are effective in closing direction. The direction of action of the resulting force from the opening and closing forces determines the spool position of the 2-way cartridge valve.
The 2-way cartridge valves can be passed from A to B or from B to A. Pressurization of area A3 by pilot oil discharge from channel B or external pilot oil supply, channel A is blocked without leakage.

2) | 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*. |
