Proportional Directional Valve 4WRZ32W8-360-7X/6EG24N9K4/V - Bosch Rexroth R900958404

Moving a large axis slowly and under control means choosing a nominal flow below the maximum the size allows. The 4WRZ32W8-360-7X/6EG24N9K4/V provides 360 l/min with spool symbol W8, is supplied and drained externally and works up to 350 bar.

Benefits

• Spool symbol W8 in size 32, 360 l/min nominal flow across 4 ports.
• External pilot oil supply and external pilot oil return separate the pilot circuit from the main circuit.
• This version carries no pressure reducing valve in the pilot stage, operating pressure reaches 350 bar.
• The amplifier sits outside the valve, and supply is 24 VDC through a 7-pole connector (6 + PE) to EN 175201-804.
• FKM seals, HL fluid, mounting pattern ISO 4401-10-09-0-05, maximum flow 1600 l/min, 43.4 kg weight.

Applications

It is typically installed in drawing presses, stretching lines and test rigs where speed has to stay uniform. The separate pilot supply gives every valve in the group the same response. Control comes from an external amplifier card.
