The Bosch Rexroth M-Z4SEH 16 E2X/3CG24K4 (R901102934) is a high-performance directional seat valve with electrohydraulic actuation, designed for reliable control in hydraulic systems. This valve is part of the SEH series, known for its capability to switch or shut off flow through one or two channels, depending on the configuration. It is constructed from a robust housing that includes a pilot operated check valve installation set and a pilot control valve, as well as blanking plugs for the pilot oil supply. The operational functionality of the M-Z4SEH 16 E2X/3CG24K4 valve is pressure-dependent, utilizing forces generated by both a compression spring and pressure in the control chamber to close, while pressures in channels A and B encourage opening. The balance between these forces dictates the position of the check valve installation sets. Pilot pressure application or unloading is managed via the pilot control valve and can be sourced from various channels based on system requirements. This model offers flexibility with multiple versions available for different pilot oil supply configurations: XY (external supply via X channel and external return via Y channel), PY (internal supply from P channel and external return via Y channel), PT (internal supply from P channel with internal return via T channel), and XT (external supply from X channel with internal return via T channel). Each version has specific porting arrangements on the subplate to accommodate these configurations. The M-Z4SEH 16 E2X/3CG24K4 also features wet-pin DC solenoids, manual override options, and electrical connections for individual wiring setups. It adheres to ISO NG porting patterns, ensuring compatibility with industry-standard interfaces. This versatility makes it suitable for various locking and pass-through functions in hydraulic systems that require precise control and leakage-free operation.
