Directional Spool Valve H-4WEH25HD6X/6EG24N9S2K4 - Bosch Rexroth R900700921

Several large directional valves sit side by side on one manifold and share the pilot lines. The H-4WEH25HD6X is built for that with external pilot oil supply and external return and switches 700 l/min.

Benefits

• External pilot oil supply and external pilot oil return for valve banks with a shared pilot circuit.
• 700 l/min of flow in size 25.
• Spool symbol D with two switching positions across four ports.
• Maximum operating pressure of 350 bar at the pilot-operated main stage.
• 18.24 kg, subplate mounting to ISO 4401-08-08-0-05, 24 V DC solenoid.

Applications

Valve banks are used on press lines, in steelworks and on large test installations. A shared pilot circuit saves lines and makes the behaviour of all axes comparable. NBR seals are fitted for HL hydraulic fluid.
