Description
Based on the official Rexroth technical documentation, your specified Type WMM valve in NG6 size is confirmed. This direct-operated directional spool valve is designed with a hand lever for reliable manual control of hydraulic flow direction and meets your key specifications: a maximum operating pressure of 315 bar, a flow rate of 60 L/min, and porting patterns compliant with DIN 24340 Form A and ISO 4401 .⚙️ Product SpecificationsYour requirements match the established technical data for the WMM series (NG6).Parameter Specification Source(s)Valve Type WMM - Manual directional spool valve Nominal Size (NS) 6 (NG6 / CETOP 3) Maximum Operating Pressure 315 bar (at P, A, B ports) Maximum Flow (Qmax) 60 L/min Actuation Hand lever Porting Pattern DIN 24340 Form A, ISO 4401-03-02-0-05, CETOP-RP 121H 🔧 Understanding Spool Types and OrderingThe valve is available in a variety of spool symbols (A, B, C, etc.) to provide different flow configurations and circuit functions (e.g., 4/3, 4/2, 3/2-way). The letter in the model number, such as 4WMM6D6X, denotes the specific spool type .A key variant is the detent version, indicated by /F in the model number (e.g., 4WMM6D5X/F). This locks the spool in each position for stable, hands-free operation . A typical ordering code follows the structure: 4WMM 6 6X/... . A notable operational note is that port T (return) has a significantly lower pressure rating of 160 bar .
