Proportional Directional Valve 4WRZE25W6-325-7X/6EG24N9K31/F1V - Bosch Rexroth R901122968

A dedicated pilot circuit holds pilot pressure steady even when working pressure collapses. That is what this build is made for, with external supply as well as external drain, 325 l/min nominal flow at a 870 l/min limit.

Benefits

• External pilot oil supply plus external drain, pilot pressure stays independent of working pressure
• 325 l/min nominal flow, 870 l/min flow limit, 350 bar operating pressure
• Current command 4...20 mA into on-board electronics, 24 VDC supply
• Spool symbol W6, 3 switching positions across 4 ports, concealed manual override
• FKM seals for HL fluid, UKCA to SI2016/1091, mass 20.58 kg

Applications

Plants with widely swinging working pressure, forging hammers or scrap presses among them, benefit from a separate pilot feed. While heavy loads are lowered, the pilot stage keeps its authority. Mounting is on a subplate to ISO 4401-08-08-0-05.
