Rexroth BOSCH Proportional Directional Valve – Type 5WRZE 52 E3-1000-7X · 模型 48353
The 5WRZE is a pilot-operated proportional directional valve from Bosch Rexroth, designed for controlling the direction and flow rate of oil in high-flow hydraulic systems . This large-size valve uses a pilot control valve to proportionally move the main spool, enabling it to handle very high flow rates. Model Code Breakdown (5WRZE-52-E3-1000-7X): Code Meaning 5 5 main ports (P, T, A, B, and R for NG52) WRZE Pilot-operated proportional directional valve with on-board electronics (OBE) 52 Size 52 E3 Spool symbol (standard 5/3-way) 1000 1000 L/min nominal flow 7X Component series 70...79 (installation dimensions unchanged) Key Specifications: Parameter Value Max. Operating Pressure 350 bar Max. Flow 2800 L/min Nominal Flow 1000 L/min Supply Voltage 24 VDC Mounting Pattern ISO 4401 Seals FKM (Viton) / NBR depending on version Design & Operation: · Pilot-operated – Uses a NG6 pilot control valve to hydraulically shift the main spool · With OBE – Integrated electronics eliminate need for separate amplifier · Spring-centered – Spool returns to neutral when de-energized · 5 main ports – Includes additional "R" port for the NG52 size ⚠️ Critical Design Considerations: · Internal leakage is inherent to the design and may increase over the life cycle · Pilot oil supply can be internal (via P port) or external (via X port) · Manual override is optional and should be used with caution to avoid uncontrolled machine movements Typical Applications: · Large hydraulic presses · Steel mills and heavy industry · High-flow mobile hydraulics · Test benches and large machine tools All designs are original engineering work based on Rexroth specifications.
