The 4WEH16P7X/6EW110N9S2K4 CSA directional spool valve is produced by Bosch Rexroth for the WEH Directional Spool Valves series. Designed for hydraulic automation tasks, it steers flow through a nominal size NG16 body that incorporates a 4-way passage network and a spool marked by symbol P. A spring-centered return brings the spool back to neutral when pilot pressure is removed, and the three-position element begins to shift once 14 bar is applied to the pilot ports. The pilot cavities hold 5.72 cm³ of fluid, supporting repeatable switching behavior. When system pressure at ports p, a, and b reaches 280 bar, the valve carries up to 170 l/min; at a reduced 70 bar the permissible flow climbs to 300 l/min.
The pilot circuit can be charged to a maximum of 250 bar, the same limit assigned to port T, while port Y adheres to a 160 bar ceiling to protect auxiliary drains. Interface geometry follows ISO 4401-07-07-0-05, and attachment to a manifold uses four M10 × 60 screws compliant with ISO 4762. Switching delay can be modified through the S2 adjustment, allowing the user to match valve timing to machine cycles. Hydraulic fluid introduced to the unit must satisfy ISO 4406 class 20/18/15 to preserve internal clearances and sealing surfaces.
