Proportional Directional Valve 4WRZ32E1-520-7X/6EG24N9K4/M - Bosch Rexroth R900244192

The larger the main flow, the less the pilot stage should depend on it. The 4WRZ32E1-520-7X/6EG24N9K4/M separates both cleanly: 520 l/min nominal flow in the main channel, pilot oil from an external circuit and return through a dedicated line.

Benefits

• 520 l/min nominal flow, peaks up to 1600 l/min, sized for the main axis of a large press.
• Pilot oil fed in and drained externally, pilot pressure and relief are decoupled from the main flow.
• 350 bar maximum operating pressure on the ISO 4401-10-09-0-05 pattern in size 32.
• Spool symbol E1, 43.35 kg weight, including concealed auxiliary actuation for setup mode.
• NBR seals, HL hydraulic fluid, commanded at 24 VDC through a 7-pole (6 + PE) plug.

Technical data

Applications

The valve serves presses, stretching lines and large lifting gear that move big oil volumes on every cycle. The external pilot circuit can run together with other pilot-operated valves of the plant. In maintenance the valve replaces identical units of the same pilot variant.
