The Bosch Rexroth M-Z4SEH10E2X/3CG96N9PYK4/F (R901325334) is a high-performance directional seat valve designed for precise control in hydraulic systems. This electrohydraulically actuated valve is part of the MZSEH series, characterized by its robust construction and versatility in application. The valve features a housing, a pilot operated check valve installation set, and a pilot control valve. It offers leak-free operation, allowing for efficient flow direction switching or shutoff through one or two channels.
Functionally, the M-Z4SEH10E2X/3CG96N9PYK4/F operates on pressure dependency; forces generated by pressure in the control chamber and compression spring work against those in the channels A and B to determine the spool's position. The pilot pressure is applied or relieved through the pilot control valve, which can be supplied with oil via various configurations—internally from channel P or externally from channel X—depending on the version of the valve.
The model code indicates specific features: an external pilot oil supply through channel X and an external pilot oil return through channel Y (XY version). This particular configuration ensures that the valve can be integrated into systems requiring an external source for pilot oil supply and return.
This sandwich plate valve supports wet-pin DC solenoids and offers multiple locking and pass-through function combinations. It includes manual override options for emergency or manual operations. The electrical connection is designed as an individual connection, adding to its ease of integration into various system designs.
With a maximum operating pressure of up to bar and a maximum flow rate of l/min, this Bosch Rexroth directional seat valve stands as a reliable component suitable for demanding hydraulic applications where precise flow direction control is essential.

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.
