Proportional Directional Valve 4WRZE25W6-325-7X/6EG24N9ETK31/F1V - Bosch Rexroth R901133816

A 4...20 mA current command makes control of this valve immune to voltage drop over long cable runs. Behind it works a pilot-operated main spool rated 325 l/min nominal flow, 870 l/min flow limit at 350 bar operating pressure.

Benefits

• Current command 4...20 mA, insensitive to cable length as well as electrical noise
• 325 l/min nominal flow at 350 bar, flow limit 870 l/min
• Pilot oil supplied internally, drained internally, no extra piping needed
• Spool symbol W6 with 3 switching positions, concealed manual override
• FKM seals for HL fluid, UKCA to SI2016/1091, size 25 at 20.58 kg

Applications

A current interface pays off in rolling mills, foundries and paper machines where cabinet and valve sit far apart. The fully internal pilot path allows a compact manifold layout. For emergencies the concealed manual override remains reachable.
