Proportional Directional Valve 4WRKE32W8-400L-3X/6EG24ETK31/A1D3V - Bosch Rexroth R901249056

An oversized valve makes the control loop nervous, because small command changes release a lot of flow. The 4WRKE32W8-400L-3X/6EG24ETK31/A1D3V is therefore rated at 400 l/min nominal flow and 350 bar.

Benefits

• 400 l/min nominal flow, finer resolution than the 600 l/min step at the same size 32.
• 1550 l/min maximum flow as headroom for short fast strokes.
• Plus minus 10 V command value on a 24 VDC supply, electronics integrated in the valve.
• Internal pilot oil supply and internal pilot oil return, no separate pilot circuit required.
• 350 bar operating pressure at 37 kg weight, FKM seals, HL hydraulic fluid.

Application

The rating suits cylinders whose speed must stay bounded, for example in force control on presses and testing machines. With symbol W8 and three switching positions it replaces existing valves of the same symbol directly. Sizing at 400 l/min keeps power loss and oil heating lower than an oversized step would.
