Directional Spool Valve H-4WEH25G6X/6EG24N9K4/P4,5 - Bosch Rexroth R901179658

From size 25 upwards the subject is large cylinders and short cycle times. This pilot-operated directional spool valve carries up to 400 l/min at 350 bar maximum operating pressure and is switched through a small pilot circuit on 24 V DC.

Benefits

• 400 l/min maximum volume flow in size 25, without an extra parallel arrangement
• 350 bar maximum operating pressure across all four ports
• Spool symbol G with three switching positions, external pilot oil supply and external pilot oil return
• 24 V DC supply, 3-pole (2 + PE) connector to EN 175301-803
• Mounting pattern ISO 4401-08-08-0-05, 18.08 kg weight, NBR seals for HL hydraulic fluid

Application

Valves of this size work in presses, forging lines, injection moulding machines and heavy duty hydraulic drives. Because pilot oil is fed and returned externally, pilot pressure stays independent of working pressure. The pilot circuit needs only a fraction of the main flow.
