Proportional Directional Valve 4WRKE32E400L-3X/6EG24K31/A1D3V - Bosch Rexroth R901199629

When the pilot circuit of a valve has to stay fully separated from the working circuit, pilot oil is supplied and drained externally. The 4WRKE32E400L-3X/6EG24K31/A1D3V is built that way and meters 400 l/min rated flow with FKM seals and a plus or minus 10 V voltage command.

Benefits

• Pilot oil supplied and drained externally, so pilot pressure can be set independently of working pressure.
• 400 l/min rated flow in size 32 at a maximum flow of 1550 l/min.
• FKM seals for HL hydraulic fluid, installed mass 37.06 kg.
• Command value plus or minus 10 V into the on-board electronics, 24 VDC supply through a 7-pole connector (6 + PE) to EN 175201-804.
• Spool symbol E, 3 switching positions, 4 ports, maximum operating pressure 350 bar.

Applications

This build suits plants with a dedicated pilot pump, or working circuits that deliver too little pilot pressure at small setpoints. The external drain keeps the pilot circuit depressurised even when the plant return line is loaded. Test rigs and forming equipment in size 32 are typical.
