Directional Spool Valve 4WEH16HD7X/6EG24N9EK4/12B15 - Bosch Rexroth R901133276

Maximum operating pressure of 280 bar sets the limit for subplate, fittings and relief valve on the 4WEH16HD7X/6EG24N9EK4/12B15. The pilot-operated size 16 spool passes up to 300 l/min and uses spool symbol D across two switching positions on four ports. Pilot supply is internal, pilot drain external, and the valve weighs 9.5 kg.

Benefits

• 280 bar maximum operating pressure in the main circuit
• up to 300 l/min flow, size 16
• spool symbol D across 2 switching positions on 4 ports
• subplate mounting to connection diagram ISO 4401-07-07-0-05
• 24 VDC solenoid actuation, 3-pole connector (2 + PE) to EN 175301-803
• NBR seals for HL hydraulic fluid, 9.5 kg weight

Applications

The valve runs in circuits filled with HL hydraulic fluid, on clamping cylinders, feed drives and power units in plant engineering. Set the relief valve of the power unit below 280 bar. The external pilot drain needs its own line back to tank, which has to be planned into the piping.
