Total price
Large press and rolling mill axes demand flow rates that size 25 no longer covers. This pilot-operated size 32 proportional valve puts 520 l/min nominal flow on the axis, holds pilot pressure steady through an integrated pressure reducing valve and is driven by an external amplifier.
Benefits
- 520 l/min nominal flow, with up to 1600 l/min possible across the valve
- An integrated pressure reducing valve in the pilot circuit keeps control pressure independent of system pressure up to 350 bar
- External pilot oil supply with internal pilot oil return
- Spool symbol W8, three switching positions, four ports, ISO 4401-10-09-0-05 port pattern
- Concealed auxiliary actuation for commissioning without a signal
- 24 VDC supply through a 3-pole (2 + PE) connector, weight 43.66 kg
