Proportional Directional Valve 4WRZE32E520-7X/6EG24N9K31/A1D3M - Bosch Rexroth R900737261

A separate control oil unit is standard on large presses, because switching times as well as repeatability depend on it. The 4WRZE32E520-7X is built for that, drawing pilot oil externally, discharging it externally, while controlling 520 l/min at 350 bar.

Benefits

• External pilot supply with external drain keeps switching times clear of the main circuit state.
• Spool symbol E in three switching positions across four ports.
• 520 l/min nominal flow in size 32, flow limit 1600 l/min.
• ±10 V command on 24 VDC, on-board electronics without a separate amplifier card.
• 350 bar operating pressure, NBR seals, HL hydraulic fluid, 44 kg.
• ISO 4401-10-09-0-05 subplate mounting with a 7-pole connector (6 + PE) to EN 175201-804.

Application

Hydraulic presses, deep drawing lines or testing machines with their own control oil loop are the field of use. Since the pilot circuit works independently, acceleration as well as braking ramps stay repeatable across the whole cycle. Concealed auxiliary actuation permits movement without control voltage.
