Proportional Directional Valve 4WRZ32W6-520-7X/6EG24N9K4/M - Bosch Rexroth R900957303

A fully separate pilot circuit can be filtered and cooled on its own. The 4WRZ32W6-520-7X/6EG24N9K4/M is laid out for that and controls 520 l/min nominal flow with spool symbol W6.

Benefits

• Pilot oil fed in and drained externally, dedicated circuit for filtering and cooling.
• 520 l/min nominal flow, flow up to 1600 l/min.
• Spool symbol W6, three switching positions, subplate mounting.
• 350 bar maximum operating pressure, ISO 4401-10-09-0-05 pattern.
• 43.71 kg weight, NBR seals, concealed auxiliary actuation.

Applications

The valve is used in large plants where pilot oil is conditioned separately. That keeps the pilot stage clean even when the main circuit is heavily loaded. For a swap, check mounting pattern, symbol and pilot variant.
