Directional Spool Valve 4WEH10HD4X/OF6EG24N9S2K4 - Bosch Rexroth R901004591

The suffix OF in the type code marks pilot control without a channel of its own inside the valve, so both pilot paths lie outside. The port pattern follows ISO 4401-05-05-0-05 and the spool carries symbol D across two positions.

Benefits

• External pilot oil supply and external drain, pilot stage fed from its own source
• Spool symbol D with 2 switching positions and 4 ports
• Flow up to 160 l/min at an operating pressure of 280 bar maximum
• Size 10 with a port pattern to ISO 4401-05-05-0-05, mass 8.35 kg
• Solenoids at 24 VDC, connector 3-pole (2 + PE) according to EN 175301-803, NBR seals

Application

The valve steers cylinders in machines that carry a separate control pressure supply. Since pilot pressure stands ready regardless of working pressure, it also shifts during start-up at low system pressure. Flow up to 160 l/min matches feed and clamping axes.
