Directional Spool Valve H-4WEH25C6X/6EG24NK4 - Bosch Rexroth R900718178

A fully external pilot oil path makes the switching behaviour independent of the main circuit. This pilot-operated directional spool valve in size 25 works that way and moves flow of up to 700 l/min.

Benefits

• External pilot oil supply and external pilot oil return, pilot stage independent of the main circuit.
• Spool symbol C on 4 ports with 2 switching positions.
• Flow up to 700 l/min, maximum operating pressure 350 bar.
• 17.58 kg weight, connection diagram ISO 4401-08-08-0-05, NBR seals.
• 24 VDC supply voltage, HL hydraulic fluid.

Application

Valves of this kind sit in manifolds of presses and lifting gear whose pilot pressure comes from a small auxiliary pump. Pilot pressure is therefore kept even when the working pressure collapses. Wiring runs through a 3-pole connector (2 + PE) to EN 175301-803.
