The Bosch Rexroth M-Z4SEH10E2X/3CG24PTK4/F (R901335438) is a high-performance directional seat valve designed for precise control in hydraulic systems. It features electrohydraulic actuation and can be configured to switch or block flow through one or two channels, ensuring versatile application across various hydraulic circuits. This model is part of the MZSEH series and incorporates a pilot-operated check valve installation set, a pilot control valve, and blanking plugs for the pilot oil supply.
The valve operates with a pressure-dependent function, where the compression spring and pressure in the control chamber exert closing force, while pressures in channels A and B influence the opening direction of the valve spool with spool sealing. The final switching position is determined by the balance of these forces. Pilot pressure application or unloading is managed via the pilot control valve, with supply sourced from the highest pressure among channels A, B, P, or X.
This particular model offers different versions for pilot oil supply and return configurations: XY version uses external sources from channel X; PY version uses internal sources from channel P; PT version also uses internal sources from channel P but returns oil internally via channel T; XT version combines an external supply from channel X with an internal return through channel T.
As a sandwich plate valve with electrohydraulic actuation conforming to ISO NG6 and ISO NG10 porting patterns, it supports maximum operating pressures up to 350 bar and maximum flow rates as required by specific applications. It can be equipped with various locking and pass-through functions along with optional manual override capabilities. The electrical connection is designed for individual wiring setups. This model ensures leak-free operation while offering flexibility in hydraulic system design due to its various internal and external pilot oil supply options.

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!
