Proportional Directional Valve 4WRZ16E180-7X/6EG24N9K4/D3M - Bosch Rexroth R901459682

If the main line drops to low values during operation, an internally supplied pilot stage loses its working basis. The pilot-operated proportional directional valve 4WRZ16E180-7X/6EG24N9K4/D3M therefore draws its pilot oil from outside and meters a nominal flow of 180 l/min in size 16.

Benefits

• External pilot oil supply and external pilot oil return, pilot stage works independently of the main line.
• Nominal flow 180 l/min, maximum flow 460 l/min, operating pressure up to 350 bar.
• Version with pressure reducing valve, spool symbol E, three switching positions on four ports.
• Concealed auxiliary actuation for commissioning and fault finding.
• Electrical control with external electronics, 24 VDC, connector 7-pole (6 + PE) to EN 175201-804, weight 12 kg.

Technical data

Application

The valve controls axes in presses and test rigs whose system pressure varies strongly or is lowered at times. Operation requires an external pilot oil source and amplifier electronics. NBR seals and HL hydraulic fluid define the permitted fluid range.
