Directional Spool Valve 4WEH16L7X/6EG24N9ES2K4/10B08 - Bosch Rexroth R900617871

The type code 4WEH16L7X/6EG24N9ES2K4/10B08 describes a pilot-operated spool valve carrying symbol L, an internal pilot oil supply and an external pilot oil return. In size 16 it passes 300 l/min and holds 280 bar operating pressure at 11.32 kg.

Benefits

• Spool symbol L, three switching positions, 4 ports to ISO 4401-07-07-0-05
• 300 l/min flow at a maximum operating pressure of 280 bar
• Internal pilot oil supply from port P, external pilot oil return
• 24 VDC solenoid actuation through a 3-pole connector (2 + PE) to EN 175301-803
• 11.32 kg, NBR seals, HL hydraulic fluid

Application

The valve drives double-acting cylinders that should stand relieved in the centre position, for example in presses and test rigs. Because the pilot drain runs outside the valve, back pressure at port T does not act on the pilot stage. An existing size 16 valve station takes it unchanged.
