Directional Spool Valve 4WEH32G6X/6EG24N9K4/10 - Bosch Rexroth R901077797

Where a dedicated pilot circuit with stable pressure is available, external piloting is the sensible choice. The 4WEH32G6X/6EG24N9K4/10 is built for exactly that, with pilot supply and pilot return brought out. In size 32 it switches up to 900 l/min in three positions to symbol G.

Benefits

• External pilot supply and external return, keeping pilot pressure independent of main pressure
• 900 l/min flow at an operating pressure of up to 280 bar
• Three switching positions across four ports, switching diagram symbol G
• 3-pole connector (2 + PE) to EN 175301-803 at 24 VDC supply voltage
• NBR seals, released for HL hydraulic fluid
• 37.38 kg valve mass on the ISO 4401-10-09-0-05 mounting pattern

Application

An external pilot circuit pays off in systems whose main pressure fluctuates strongly or temporarily falls below the minimum pilot pressure, for instance with accumulator operation or pumps under zero stroke control. The valve keeps working because its pilot stage is fed from a separate source.
