Proportional Directional Valve 4WRZE32W8-360-7X/6EG24N9ETK31/F1D3V - Bosch Rexroth R901163311

A power unit without a separate pilot pump still has to drive a large axis proportionally. This version with fully internal pilot supply does that with 360 l/min nominal flow and an operating pressure of up to 350 bar.

Key benefits

• Fully internal pilot supply, so neither an extra pilot pump nor external control lines are needed.
• Spool symbol W8 with three switching positions and four ports for cylinders with a defined mid position.
• 360 l/min nominal flow, with a permitted flow of 1600 l/min.
• A pressure reducing valve in the pilot circuit separates control pressure from working pressure up to 350 bar.
• A 7-pole connector (6 + PE) to EN 175201-804 joins the 24 VDC supply and the 4 to 20 mA command in one step.

Applications

Size 32 is applied on presses, shears and hoists in which one cylinder takes several hundred litres of oil per stroke. Subplate mounting to ISO 4401-10-09-0-05 allows a swap against an existing valve of the same size without changing the piping. FKM seals are rated for higher oil temperatures.
