Proportional Directional Valve 4WRZE32W6-520-7X/6EG24N9EK31/A1D3M - Bosch Rexroth R901062036

On the clamping unit of an injection moulding machine system pressure is present almost continuously, while cooler plus filter build back pressure in the return. The 4WRZE32W6-520-7X matches that with internal pilot oil supply alongside an external pilot drain, rated for 520 l/min at 350 bar.

Benefits

• Pilot oil taken internally, drained externally saves a feed line while keeping the drain free of back pressure.
• 520 l/min nominal flow in size 32, up to 1600 l/min possible.
• ±10 V command into on-board electronics, supply 24 VDC.
• Spool symbol W6, three switching positions, four ports.
• 350 bar operating pressure, NBR seals, HL hydraulic fluid, 43.78 kg.
• ISO 4401-10-09-0-05 interface with a 7-pole connector (6 + PE) to EN 175201-804.

Application

Besides clamping units, core pull axes as well as ejector drives are typical applications where cycle time meets repeatability. Because the pilot drain runs separately, switching time stays constant even at high return pressure. Concealed auxiliary actuation serves setup work along with emergencies.
