Directional Spool Valve H-4WEH25Y6X/6EG24N9S2K4 - Bosch Rexroth R900704998

An axis running in shift operation switches thousands of times a day and its pilot supply should stay independent of the main circuit. The H-4WEH25Y6X draws pilot oil externally and switches 700 l/min to spool symbol Y.

Benefits

• External pilot oil supply and external pilot oil return, independent of the pressure in the main circuit.
• Spool symbol Y with two switching positions across four ports.
• 700 l/min of flow in size 25 at a maximum of 350 bar.
• 18.18 kg, subplate mounting to ISO 4401-08-08-0-05.
• 24 V DC solenoid through a 3-pole connector (2 + PE) to EN 175301-803, NBR seals.

Applications

Axes in shift operation are found in presses, injection moulding lines and handling equipment. A dedicated pilot supply keeps switching times stable even when system pressure varies through the cycle. Spool symbol Y defines how the ports connect at rest.
