Rexroth BOSCH Proportional Directional Valve – Type 4WRA 10 W60-2X · 模型 48367
The 4WRA is a direct-operated proportional directional valve for controlling the direction and magnitude of oil flow without electrical position feedback . "10" refers to the nominal size (NG10/CETOP D05), and "W60" defines the spool symbol and nominal flow . Model Code Breakdown (4WRA-10-W60-2X): Code Meaning 4WRA 4 main ports; direct operated proportional valve; requires external control electronics 10 Nominal size 10 (NG10); ISO 4401-05-04-0-05 subplate mount W Hydraulic spool symbol W 60 Nominal flow: 60 L/min at Δp = 5 bar per control edge 2X Component series 20–29 (unchanged installation dimensions) Key Specifications: Parameter Value Operating Pressure (P, A, B) Up to 315 bar Operating Pressure (T) Up to 210 bar Nominal Flow 60 L/min Max Flow 75 L/min Mounting Pattern ISO 4401-05-04-0-05 (NG10/D05) Seals FKM (Viton) Weight ~6.6 kg Design & Operation: · Direct operated with proportional solenoids (central thread, detachable coil) · Spring-centered control spool returns to neutral when de-energized · Progressive flow characteristics through orifice-type cross-sections · Requires external control electronics for proportional actuation · Compatible fluids: Mineral oils (HL, HLP) and fire-resistant fluids (HFDU, HFDR) Typical Applications: · Industrial hydraulics (presses, machine tools) · Automation systems requiring precise flow/direction control · Closed-loop hydraulic circuits without position feedback All designs are original engineering work.
