Proportional Directional Valve 4WRKE16W6-150L-3X/6EG24TK31/A1D3M - Bosch Rexroth R901492716

In a continuous casting line the oscillation axis moves without pause inside a narrow tolerance band. The 4WRKE16W6-150L-3X/6EG24TK31/A1D3M serves it with 150 l/min nominal flow, draws pilot oil from a filtered external circuit and returns it internally to tank.

Benefits

• External pilot supply, internal pilot drain, filtered pilot oil with just one extra line
• 150 l/min nominal flow, maximum flow 460 l/min in size 16
• Spool symbol W6 with a linear curve, well suited to cyclic motion profiles
• 350 bar operating pressure on the ISO 4401-07-07-0-05 pattern
• ±10 V command value, 24 VDC, 12.05 kg, NBR seals for HL hydraulic fluid

Applications

The valve is used on oscillation and withdrawal axes in continuous casting and on other plants running permanently cyclic duty. Clean pilot oil from the auxiliary circuit keeps the pilot stage serviceable over long running times. The internal drain saves the second pilot line on the manifold.
