Proportional Directional Valve 4WRTEM16W6-220L-4X/6EG24K31/A1M - Bosch Rexroth R901484633

When a press runs on accumulator supply, falling system pressure must not reach the pilot stage. The 4WRTEM16W6-220L-4X/6EG24K31/A1M is therefore fed through X and relieved through Y, at 220 l/min nominal flow and operating pressures up to 350 bar.

Benefits

• 220 l/min nominal flow in size 16 against a series maximum flow of 460 l/min.
• External pilot oil supply and external return, independent of P and T.
• Spool symbol W6 with 3 switching positions and a linear characteristic across the full stroke.
• Plus or minus 10 V command, 24 VDC supply at a 7-pole connector (6 + PE) to EN 175201-804.
• Mounting pattern ISO 4401-07-07-0-05, NBR seals for HL mineral oil, weight 11.5 kg.

Applications

The mounting place is accumulator presses, die cushions and lifting gear under changing load. 220 l/min nominal flow allows brisk rapid strokes at medium to large piston areas. Position feedback inside the valve corrects spool deviations on its own.
