This valve meters direction and volume of a fast large axis: 400 l/min nominal flow at 350 bar operating pressure, with a flow limit of 1250 l/min. An internal transducer reports spool position, the closed-loop electronics sit on the valve itself.

Benefits

• 400 l/min nominal flow at 350 bar operating pressure, flow limit 1250 l/min
• IO-Link over the M12 x 1 connector, coding A, carries command value, actual value and device data on one line
• On-board electronics replace a separate amplifier card, supply 24 VDC
• ISO 4401-08-08-0-05 interface with 4 ports in 3 switching positions, subplate mounting
• Spool symbol E, NBR seals for HL fluid, CE marked at a mass of 19.34 kg
