The 4WH16G7X/ valve belongs to the WEH Directional Spool Valves series and is produced by Bosch Rexroth for hydraulic automation tasks that require controlled flow direction. Valve size is NG16, allowing installation in medium-flow circuits, and it mounts on subplates that follow porting pattern ISO 4401-07-07-0-05 for interchangeability with standard CETOP 07 components. At 280 bar on ports P, A, and B the valve handles a flow of 210 l/min, supporting rapid cylinder or motor movement. The design accepts hydraulic media with viscosities between 2.8 and 500 mm²/s, and the operating fluid can be between –20 °C and +80 °C while ambient temperature is limited to –20 °C to +50 °C. Oil cleanliness must meet ISO 4406 20/18/15 to prevent spool sticking.
Pilot actuation is supplied externally on X and Y lines, so the main ports remain unpressurized during standby. The pilot circuit must deliver at least 14 bar to shift the spring-centered three-position spool and may rise to 250 bar without overstressing the control stage; the same 250 bar limit applies to pilot return line Y and to the tank port T. Each switching cycle consumes 5.72 cm³ of pilot oil, which assists in sizing the supply accumulator. Mechanical fastening uses M10 screws tightened to 58 Nm with a ±10 % tolerance to secure the body against manifold leakage, and the installed mass is 7.3 kg for manual handling during maintenance.
