Proportional Directional Valve 4WRDE16V220L-6X/VXYWG/24A1 - Bosch Rexroth R901537033

Where a size 16 cylinder has to extend quickly and still stay under control, nominal flow decides. The 4WRDE16V220L-6X/VXYWG/24A1 delivers 220 l/min, 70 l/min more than the 150 version on the same interface, and holds the spool on a ±10 V command value through internal position feedback.

Benefits

• 220 l/min nominal flow with a maximum flow of 460 l/min.
• Operating pressure up to 350 bar on an ISO 4401-07-07-0-05 interface, size 16.
• On-board electronics process ±10 V without a separate amplifier card.
• External pilot oil supply and external pilot oil return keep the control circuit clear of pressure peaks.
• FKM seals, 3 switching positions, spool symbol V, 10.5 kg.

Applications

The 220 l/min step targets axes that cover a long stroke in a short time, for example closing movements on injection moulding machines or feed drives in rolling mills. The analog command value throttles that flow steadily, so the end position is approached softly.

Manufacturer

Bosch Rexroth, material number R901537033. The type code 4WRDE16V220L-6X/VXYWG/24A1 differs from the 150 version only in nominal flow, while size, spool symbol V and electronics stay the same.
