Proportional Directional Valve 4WRZE32W6-520-7X/6EG24N9K31/A1D3V - Bosch Rexroth R900964254

In circuits with strongly fluctuating or temporarily low system pressure, pilot control has to come from its own source. The 4WRZE32W6-520-7X/6EG24N9K31/A1D3V therefore uses external pilot oil supply and external pilot oil return while still providing 520 l/min nominal flow.

Benefits

• External pilot oil supply and external pilot oil return, independent of main circuit pressure
• 520 l/min nominal flow, max. flow 1600 l/min
• ±10 V command, 24 V DC supply via 7-pole connector (6 + PE) to EN 175201-804
• Spool symbol W6, 3 switching positions, 4 ports
• Max. operating pressure 350 bar, FKM seals for HL hydraulic fluid
• Weight 43.95 kg

Applications

Intended for systems with a separate control circuit, for example large presses with their own pilot pump or accumulator circuits whose pressure can drop below the minimum pilot pressure. The external return carries pilot oil separately to tank and keeps the pilot circuit clear of return line back pressure.
