Proportional Directional Valve 4WRZ32W6-520-7X/6EG24N9K4/D3V - Bosch Rexroth R900942516

A separate pilot circuit for supply and return keeps the characteristic curve independent of pressure swings in the main circuit. This size 32 version sets 520 l/min nominal flow at operating pressures up to 350 bar.

Advantages

• External pilot oil supply and external return, separate pilot circuit
• Nominal flow 520 l/min, maximum flow up to 1600 l/min
• Symbol W6 opens all four ports in mid position
• Pressure reducing valve in the pilot stage, concealed auxiliary actuation
• External amplifier electronics, 24 VDC supply, operating pressure up to 350 bar
• FKM seals for HL hydraulic fluid, 44.15 kg, connection diagram ISO 4401-10-09-0-05

Applications

Used on systems with accumulator charging or a variable pump at zero stroke where system pressure occasionally falls below the minimum pilot pressure. Symbol W6 relieves cylinder and lines after shutdown. A small auxiliary unit is enough for the pilot circuit.
