Directional Spool Valve 4WEH16D7X/6EG24N9SK4 - Bosch Rexroth R900939597

Pilot-operated 4-way directional spool valve of size 16 with external pilot oil supply and external pilot oil return, rated for 300 l/min. Pilot oil comes from a separate circuit, so the valve still switches reliably when pressure in the main circuit fluctuates.

Advantages

• External pilot oil supply and external pilot oil return, independent of the pressure in the main circuit
• 2 switching positions to spool symbol D across 4 ports to ISO 4401-07-07-0-05
• Flow of 300 l/min at a maximum operating pressure of 280 bar
• Connector, 3-pole (2 + PE) to EN 175301-803 on the 24 VDC solenoid
• NBR seals for HL hydraulic fluid at a weight of 10.4 kg

Application

The valve works in size 16 control blocks that already carry a separate pilot circuit, for example in presses and test rigs with several actuators. Spool symbol D defines how the 4 ports connect in both switching positions. HL is the intended hydraulic fluid and wiring runs through a 3-pole connector (2 + PE) to EN 175301-803.
