The Bosch Rexroth M-Z4SEH16E2X/3CG24PTK4/N (R901335457) is a high-performance directional seat valve designed for precise control in hydraulic systems. This sandwich plate valve, which belongs to component series X, is characterized by its electrohydraulic actuation and compatibility with porting patterns according to ISO NG. It is engineered to handle a maximum operating pressure of up to 350 bar and can facilitate a maximum flow rate as required by the application.
This model boasts a robust design that incorporates a pilot operated check valve installation set and pilot control valve, ensuring reliable performance with leak-free operation when switching between open or blocked states. The valve's functionality is pressure-dependent, utilizing forces from compression springs and pressure in the control chamber against those generated in channels A and B. This balance of forces determines the spool's position, allowing for precise regulation of fluid flow.
The M-Z4SEH16E2X/3CG24PTK4/N offers versatility with different versions available for pilot oil supply and return configurations – including external (XY), internal from the P channel with external return (PY), internal from the P channel with internal return (PT), and external supply with internal return (XT). This flexibility enables integration into various circuit designs.
Additionally, this model can be equipped with optional features such as manual override capabilities for emergency operations and an individual electrical connection for ease of integration into existing systems. The wet-pin DC solenoid ensures reliable electric actuation under wet conditions. With its combination of locking and pass-through functions, this Bosch Rexroth directional seat valve is suitable for applications that demand precise control over fluid direction and flow within hydraulic systems.

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.
