Description:Based on the search results, here is the information for the Rexroth Type WN directional spool valve with pneumatic (fluidic) actuation at a pilot pressure of 1.5 to 6 bar. 🔧 Valve Overview The Type WN valve is a direct-operated directional spool valve that uses fluidic (pneumatic) actuation. This means it is controlled by applying a pilot pressure to a hydraulic cylinder integrated into the valve . These valves are used to control the start, stop, and direction of a hydraulic fluid flow . ⚙️ Technical Specifications For the WN 10 (size 10) variant, which is the most documented in the search results, the key specifications are as follows: Parameter Specification Valve Type WN - Directional spool valve with fluidic actuation Actuation Pneumatic (Hydraulic pilot pressure) Pilot Pressure Range 1.5 ... 10 bar (Your specified 1.5 to 6 bar falls within this range) Nominal Size 10 (NG10 / CETOP 5) Maximum Operating Pressure 350 bar (Ports P, A, B) Maximum Flow 160 l/min Porting Pattern ISO 4401-05-04-0-05 Seals NBR (standard) or FKM 🔄 Spool Symbols and Valve Configurations The valve is available in a variety of spool symbols (A, B, C, D, etc.), including the Y-Spool you mentioned, to provide different flow path configurations . It is available in 4/3, 4/2, and 3/2-way versions, meaning it can have either three or four main ports and two or three switching positions . The specific spool symbol is selected as part of the ordering code .
