Pilot control on this valve works with its own pressure reducing valve that brings pilot pressure to a fixed level. Nominal flow is 360 l/min with spool symbol W9, pilot oil returns externally and operating pressure reaches 350 bar.

Advantages

• Pressure reducing valve in the pilot stage for constant pilot pressure
• External pilot oil return with internal supply
• Nominal flow 360 l/min, maximum flow up to 1600 l/min
• Spool symbol W9, three switching positions, four ports
• External amplifier electronics on 24 VDC, concealed auxiliary actuation
• NBR seals for HL hydraulic fluid, 44.02 kg, connection diagram ISO 4401-10-09-0-05

Applications

Intended for large axes on presses and rolling mills whose return line is pressurised. The fixed pilot pressure keeps the characteristic curve repeatable across the whole load range. The concealed auxiliary actuation stays available for commissioning and emergency operation.
