Benefits

• External pilot oil supply and external return protect the pilot stage against fluctuating main pressure.
• 325 l/min nominal flow at 350 bar, up to 870 l/min flow in size 25.
• 4 to 20 mA command value on the on-board electronics, internal spool position feedback.
• Spool symbol W6, 3 switching positions, supply voltage 24 V DC.
• 20.58 kg installed weight, UKCA declaration, NBR seals for HL hydraulic fluid.

Applications

Used in forging and drawing presses, in scrap shears and in plants with strongly changing loads. A separate pilot circuit keeps switching times and the zero point stable through load changes. Connection diagram ISO 4401-08-08-0-05.
