The Bosch Rexroth M-Z4SEH10E2X/3CG96PTK4/N (R901335432) is a high-performance directional seat valve designed for electrohydraulic actuation. This particular model, part of the Type MZSEH series, offers precise control in hydraulic systems. The valve features a robust housing and includes a pilot-operated check valve installation set and pilot control valve. It operates in a leak-free manner, ensuring efficient flow direction that is independent of the flow direction when switched on or off.
The functionality of this valve is pressure-dependent, utilizing forces from compression springs and pressures in the control chamber to close, while pressures in channels A and B work to open the valve spool with spool sealing. The switching position of the check valve installation sets is determined by these opening and closing forces. Pilot pressure application or unloading is managed through the pilot control valve based on the selected pilot oil supply, which can be sourced from the highest pressure among channels A, B, P, or X.
This model comes with different versions for varied applications: XY version allows external pilot oil supply via channel X and external return via channel Y; PY version has an internal supply from P channel with external return via Y; PT version features internal supply from P channel and return via T channel; XT version combines external supply through X with internal return through T.
Equipped with wet-pin DC solenoids for reliable operation, this sandwich plate valve offers different combinations of locking and pass-through functions to suit diverse system requirements. It also includes options for manual override and individual electrical connections. The porting pattern adheres to ISO NG standards ensuring compatibility with various hydraulic systems. With its maximum operating pressure bar and maximum flow l/min specifications, it's engineered to meet rigorous demands for consistent performance in controlling fluid power within hydraulic circuits.

General
The SEH type directional valves are directional seat valves with electro-hydraulic actuation. Here, depending on the order version, it can be switched or switched off via one or two channels.
The directional valve basically consists of a housing (1), a pilot operated check valve installation set (2), pilot control valve (3) as well as blanking plugs for the pilot oil supply. The valve is free-flowing, independent from the direction, and is opened or blocked in a leakage-free manner depending on the switching position of the pilot control valve and the pressure ratio in the main valve.
Function
The function of the valve is pressure-dependent. The force of the compression spring (4) as well as the force generated by pressure in the control chamber (5) take effect in the closing direction, while the forces generated by pressure in the channels A and B take effect in the opening direction of the valve spool (6) with spool sealing. The direction of action of the resulting force from the opening and closing forces determines the switching position of the check valve installation sets (2). The pilot pressure application and/or unloading is implemented via the pilot control valve (3) depending on the selected pilot oil supply. The pilot oil supply is implemented via the respective highest pressure from the channels A, B, P or X and is secured via a check valve (7).
Notice!
For nozzles and plug fitting, please refer to the project planning information.
