Proportional Directional Valve 4WRZ32W9-360-7X/6EG24N9K4/D3M - Bosch Rexroth R901030594

Pilot supply and pilot return both run outside the main circuit here, so pilot pressure stays constant while 360 l/min nominal flow is set. Spool symbol W9, operating pressure up to 350 bar.

Advantages

• External pilot oil supply and external return, independent of the main circuit
• Nominal flow 360 l/min, maximum flow up to 1600 l/min
• Spool symbol W9, three switching positions, four ports
• Pressure reducing valve in the pilot stage, concealed auxiliary actuation
• External amplifier electronics on 24 VDC, operating pressure up to 350 bar
• NBR seals for HL hydraulic fluid, 43.6 kg, connection diagram ISO 4401-10-09-0-05

Applications

Intended for systems with accumulator charging whose pressure drops between working strokes. A small pilot power unit then supplies constant control pressure. The amplifier card in the cabinet stays accessible for adjustment and diagnosis.
