Proportional Directional Valve 4WRKE32E600L-3X/6EG24K31/A1D3M - Bosch Rexroth R900734062

A suspended load has to stay in place at standstill, so the centre position must never open to tank. The 4WRKE32E600L-3X/6EG24K31/A1D3M uses spool symbol E for that, receives pilot oil externally, is relieved externally and releases 600 l/min in the main stage at up to 350 bar.

Benefits

• Spool symbol E blocks the centre position, the load stays in place without extra poppet valves.
• External pilot supply through X and external pilot return through Y, independent of working pressure.
• 600 l/min rated flow, 1600 l/min maximum, operating pressure up to 350 bar.
• Analogue actuation with plus minus 10 V command, on-board electronics, 24 VDC supply.
• ISO 4401-10-09-0-05, 4 ports, 3 switching positions, NBR seals, 36.92 kg.

Applications

The valve is intended for lifting gear, press rams and slewing drives where the axis must not drift while stopped. External pilot supply suits power units with a dedicated pilot pump or an accumulator. With HL fluid the NBR seals work inside their standard range.
