Directional Spool Valve 4WEH16H7X/6EG24N9TS2K4 - Bosch Rexroth R900952123

The pilot-operated 4WEH16H7X/6EG24N9TS2K4 works on spool symbol H and therefore covers a circuit diagram of its own. In size 16 it passes 300 l/min at 280 bar maximum operating pressure, takes pilot oil from an external source and hands it internally to tank. Weight is 10.8 kg.

Benefits

• Spool symbol H with three switching positions and 4 ports
• External pilot oil supply, internal pilot oil return
• 300 l/min flow at 280 bar maximum operating pressure
• 10.8 kg, NBR seals, HL hydraulic fluid
• Subplate mounting to ISO 4401-07-07-0-05, 24 VDC

Application

The spool symbol decides whether a cylinder is held, unloaded or circulated in mid position. When an existing valve is replaced, that letter has to match. The external pilot source keeps the pilot stage working even when working pressure fluctuates.
