Rexroth BOSCH Proportional Directional Valve – Type 4WRA 6 E07-2X · 模型 48370
The 4WRA is a direct-operated proportional directional valve used for controlling the direction and size of hydraulic flow . The "4" indicates it has 4 main ports (P, T, A, B), and the "6" refers to the nominal size (NG6) . Model Code Breakdown (4WRA-6-E07-2X): Code Meaning 4WRA Proportional directional valve without integrated electronics (requires external control) 6 Nominal size 6 (NG6) E Spool symbol (E) 07 Nominal flow rate: 7 L/min at Δp = 10 bar 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 7 L/min at Δp = 10 bar Max Flow 22 L/min Supply Voltage 24 VDC Electrical Connection 3-pole connector (2 + PE) to EN 175301-803 Mounting Pattern ISO 4401-03-02-0-05 (NG6) Seals FKM (Viton) Weight ~3.5 kg Design & Operation: · Direct operated with proportional solenoids (central thread, detachable coil) · Spring-centered control spool returns to neutral when de-energized · No electrical position feedback – requires external control electronics · Progressive flow characteristics through orifice-type cross-sections Typical Applications: · Industrial hydraulics (presses, machine tools) · Automation systems requiring precise flow/direction control · Closed-loop hydraulic circuits
