The 3WP6A6X/OFN/5 valve is part of the WP Pneumatic Spool Valves series from Bosch Rexroth and directs hydraulic flow in automated circuits. Pneumatic actuation moves the spool, so an external air signal shifts the internal passages without the need for electrical coils. With valve size 6, it fits installation patterns common to compact hydraulic manifolds. Three main ports allow pressure supply, work connection, and return to be handled by a single body. The unit tolerates operating pressures up to 315 bar in ports a, b, and p to suit high-pressure systems. When fully shifted it passes up to 60 liters per minute, matching medium flow machines. It can be mounted in any position, and the interface follows NFPA T3.5.1 D03 for direct sub-plate assembly.
The sub-plate layout matches the ISO 4401-03-02-0-05 porting pattern, ensuring interchangeability with standard manifolds. A switching rate of 7,200 cycles per hour supports high-frequency control loops. The pilot stage requires at least 4 bar to shift the spool and accepts up to 10 bar without damage. A pilot volume of 4.24 cm³ defines the air demand for each shift. Tank port t withstands back-pressure up to 160 bar so return lines can run at elevated levels. Internal passage cleanliness must stay at ISO 4406 class 20/18/15 to prevent wear. These parameters complete its performance profile for pneumatic-pilot actuation in hydraulic automation.
