Proportional Directional Valve 4WRZ32E520-7X/6EG24N9K4/D3V - Bosch Rexroth R900958942

A nominal flow of 520 l/min meets a blocking symbol E and a fully external pilot circuit here. 520 l/min are set without pilot pressure depending on the state of the main circuit. 350 bar are permitted.

Advantages

• Nominal flow 520 l/min, maximum flow up to 1600 l/min
• Symbol E blocks in mid position and holds the load
• External pilot oil supply and external return, independent pilot circuit
• Pressure reducing valve in the pilot stage, concealed auxiliary actuation
• External amplifier electronics on 24 VDC, connection diagram ISO 4401-10-09-0-05
• FKM seals for HL hydraulic fluid, operating pressure up to 350 bar, 43.4 kg

Applications

Used on forging and forming presses with accumulator charging whose pressure swings between strokes. A separate pilot power unit supplies constant control pressure. The blocked centre holds the load as long as no signal is present.
