4WE10D4X/CG96NDK23L/V

The 4WE10D4X/CG96NDK23L/V directional spool valve is produced by Bosch Rexroth as part of the WE Directional Spool Valves series. It shifts hydraulic flow paths in automation circuits by moving a spool with a direct-acting solenoid. The NG10 nominal size accommodates medium frame manifolds and keeps pressure drop within limits on machines using standard 3/8-inch lines. Interface compatibility is defined by the D05 CETOP pattern, allowing the unit to bolt onto common subplates without adapters. The spool marked with symbol D provides a three-position, closed-center flow pattern suited for actuator holding duties during idle periods. A high-power wet-pin solenoid with a detachable coil generates the required shifting force while immersing the armature in oil for extended service life. System passages in ports P, A, and B withstand operating pressures up to 315 bar, supporting high-pressure industrial power units. When flow demand peaks, the valve can pass up to 120 liters per minute without exceeding rated differential limits.

The energizing coil draws 96 V DC, a supply level that avoids mains potential and reduces arcing at disconnection. Electrical hookup is made through a DK23L Mini-Change three-pole connector with an integral LED, giving quick-disconnect convenience and visual power indication. A recessed mechanical button provides a manual override so technicians can shift the spool during commissioning or when electrical power is absent. The return path to tank can tolerate pressures up to 160 bar, allowing remote mounted return filters without risking cavitation. Once the connector is fixed in place, the assembly meets IP65, blocking dust ingress and low-pressure water jets common in plant wash-down zones. FKM seals are installed to resist heat and aggressive hydraulic fluids such as synthetic esters. These characteristics support reliable duty cycles in mobile or stationary machines that require frequent electrical isolation yet sustained hydraulic performance.
