• Internal pilot oil supply and internal pilot oil return, no extra line
• Without pressure reducing valve in the pilot stage
• Nominal flow 180 l/min, flow up to 460 l/min
• Spool symbol W8, 3 switching positions, 4 ports
• Maximum operating pressure 350 bar, size 16, weight 11.2 kg
• Concealed auxiliary actuation, connector 7-pole (6 + PE) to EN 175201-804
