Proportional Directional Valve 4WRZE32E1-520-7X/6EG24N9EK31/F1D3M - Bosch Rexroth R900728721

Large press cylinders and hoists need cross section. The 4WRZE32E1-520-7X delivers 520 l/min nominal flow, passes 1600 l/min at peak and works up to 350 bar operating pressure, driven by a 4...20 mA current command.

Benefits

• Nominal flow of 520 l/min, size 32 connection diagram ISO 4401-10-09-0-05.
• Maximum flow of 1600 l/min for short rapid traverse phases.
• Maximum operating pressure 350 bar with NBR seals for HL mineral oil.
• Internal pilot supply with external pilot drain suits circuits carrying back pressure in the tank line.
• Current command 4...20 mA on on-board electronics, supplied at 24 VDC.
• Pilot-operated spool valve with a pressure reducing valve in the pilot stage and concealed manual override.

Application

Size 32 goes into forging and drawing presses, lift cylinders on heavy gantries and test rigs with high flow. The mass of 44.6 kg calls for a bolted manifold. The external pilot drain needs its own Y line to tank.
