Proportional Directional Valve 4WRZE32W6-520-7X/6EG24N9EK31/F1M - Bosch Rexroth R900746204

Uneven mould filling only shows on the finished casting, so the axis has to be guided cleanly. The 4WRZE32W6-520-7X/6EG24N9EK31/F1M meters up to 520 l/min at 350 bar, takes pilot oil internally and drains it separately, commanded through 4...20 mA.

Benefits

• Separate pilot drain with internal supply protects the pilot stage against back pressure in the return.
• 520 l/min nominal flow at 350 bar, the size 32 body carries up to 1600 l/min.
• 4...20 mA current command through a 7-pole connector (6 + PE) to EN 175201-804, 24 V DC supply.
• W6 spool, four ports, three switching positions, ISO 4401-10-09-0-05 interface.
• 43.32 kg, NBR seals, HL hydraulic fluid, UKCA conformity for electromagnetic compatibility.

Technical data

Applications

Besides casting plants the valve fits chill casting and core shooting machines as well as presses with long holding phases. The separate pilot drain shields the pilot circuit from back pressure. A current command stays unambiguous even in electrically noisy surroundings.
