Proportional Directional Valve 4WRKE32W8-600L-3X/6EG24K31/F1D3M - Bosch Rexroth R900709134

Interference-proof signal transmission can be combined with pilot pressure that is independent of the main circuit. This pilot-operated NG32 valve processes an impressed 4-20 mA command value while drawing pilot oil through external supply plus external return, at 600 l/min of nominal flow with a 350 bar maximum.

Benefits

• Impressed command value of 4-20 mA is unaffected by voltage drop on long cables
• External pilot oil supply with external pilot oil return holds pilot pressure steady
• Nominal flow of 600 l/min, maximum flow 1600 l/min, spool symbol W8
• Operating pressure to 350 bar, 3 switching positions, connection diagram ISO 4401-10-09-0-05
• On-board electronics on 24 VDC with internal spool position feedback, mass 37.1 kg

Application

Proven in extensive plants with a dedicated pilot pump, such as rolling mills plus large press lines. The current command value stays stable even across several hundred metres of cable. An external pilot circuit allows separate filtration along with its own pressure tapping.
