Description
Based on the official Bosch Rexroth technical documentation, a Type WMR roller-operated directional spool valve in NS6 directly meets your specifications for maximum flow and pressure, as well as the required porting patterns .The valve is a direct-operated directional spool valve, available in 4/3, 4/2, and 3/2-way versions .Technical SpecificationsThe following specifications are confirmed for the WMR valve family in NS6.Parameter Specification Source(s)Valve Type WMR - Directional spool valve, roller plunger actuated Nominal Size (NS) 6 (NG6 / CETOP 3) Maximum Operating Pressure 315 bar (at ports P, A, B) Maximum Flow (Qmax) 60 L/min Actuation Roller plunger Porting Pattern DIN 24340 Form A, ISO 4401-03-02-0-05, CETOP-RP 121 H Understanding Spool TypesThe valve is available with a variety of spool symbols (A, B, C, etc.) to provide different flow path configurations and circuit functions . The letter in the model number, such as 3WMR6B5X/, denotes the specific spool type . A detailed list of available symbols can be found in the manufacturer's documentation .Operational NotesDetent: Directional valves with a roller plunger (WMR) are generally designed without a detent mechanism, meaning the spool does not lock into position and will return to the starting position once the actuating force is removed .Port T Pressure: It is important to note that for the WMR valve, the port T (return) has a lower maximum pressure rating of 60 bar .
