M-3SED6CK1X/315CG24N9K4/P CSA

The M-3SED6CK1X/315CG24N9K4/P CSA valve belongs to the M-SED Poppet Valves series from Bosch Rexroth and serves to route flow in automated hydraulic manifolds. It is driven by a solenoid so shifting depends on an electrical command rather than pilot pressure. A wet-pin, detachable coil makes replacement possible without depressurizing the line, and the coil can be rotated 90° to align the cable with adjoining components. The unit is supplied in a normally closed CK variant, which holds all passages shut until the coil is energized. Three main ports provide P, A, and T connections for supply, work, and return, while a concealed manual override lets technicians stroke the valve during commissioning or power loss. Electrical hookup uses a DIN EN 175301-803 plug and the coil accepts 24 V DC, ensuring compatibility with standard machine wiring practices.

A leak-free blocked-port design prevents internal bypass when the valve returns to its de-energized state, protecting cylinders from unintended drift. A built-in check-valve insert permits reverse flow so actuators can retract without extra plumbing. The assembly functions as a directional poppet valve, giving positive sealing at each switching position. NBR seals resist common hydraulic oils and retain flexibility through typical operating temperatures. Position monitoring hardware is absent, which keeps the envelope compact and reduces cost, while the mating electrical connector is not included, leaving installers free to choose field-specific cable sets. Together these features support compact, energy-efficient hydraulic controls where zero leakage, straightforward electrical integration, and rapid serviceability are required.
