Directional Spool Valve 4WEH16J7X/6EG24N9K4/11B08 - Bosch Rexroth R901346830

A valve that receives its pilot supply from outside also switches when the main circuit is pressureless. The pilot-operated directional spool valve 4WEH16J7X/6EG24N9K4/11B08 uses external pilot oil supply and external pilot oil return and offers three positions to symbol J.

Benefits

• External pilot oil supply and external pilot oil return, switching independent of the main circuit.
• Symbol J in three switching positions across four ports.
• Up to 300 l/min to port pattern ISO 4401-07-07-0-05.
• Maximum operating pressure 280 bar, solenoid actuation at 24 VDC.
• 10.02 kg, NBR seals, subplate mounting, HL hydraulic fluid.

Application

While a machine starts up there is no pressure in the main circuit yet, and the axes should still move into a defined position. A separate pilot supply makes that possible. The centre position to symbol J then holds the axis until the control releases it.
