Specifications
Supplier part number: M-3SED_6_CK1X-350CG_
Name:Switching Directional Valve (Rexroth - BOSCH). - Directional Spool Valve. - Directional Spool Valve With Wet Pin Solenoids. - Type WE. - Nominal Size 6. - A : B-Spool. - Qmax = approx. 80 L/min. - Pmax = 350 bar. - Porting Pattern To DIN 24340 Form A. - I
Description:Based on the official Bosch Rexroth technical documentation, a directional spool valve with the B spool symbol (Type 4WE6B) matches your specifications for a size 6, solenoid-operated valve with wet-pin solenoids. The 'B' designation indicates the spool symbol, which defines the specific fluid flow paths when the valve is actuated. A product listing confirms a model with the "B" spool is a 3-way, 2-position (3/2) valve, featuring three ports and two switching positions. Key performance parameters confirmed for this valve series include the maximum flow and pressure ratings you specified, compliant with the listed porting standards. ✅ Confirmed Technical Specifications Parameter Specification Source(s) Valve Type WE – Directional spool valve, solenoid-operated Nominal Size 6 (NG6 / CETOP 3 / ISO 4401) Spool Type B (3/2-way) Maximum Flow (DC) 80 L/min Maximum Operating Pressure 350 bar (at ports P, A, B) Actuation Solenoid operated (wet-pin) Porting Pattern DIN 24340 Form A, ISO 4401-03-02-0-05, NFPA D03 🔧 Understanding the Valve Design The valve uses a control spool moved by one or two wet-pin solenoids, which are immersed in hydraulic fluid for quiet operation, good heat dissipation, and long service life. In the de-energized state, the spool is held in its central or initial position by return springs. When a solenoid is energized, it pushes the spool to direct flow according to the hydraulic symbol, enabling reliable switching of the oil flow direction.
