Proportional Directional Valve 4WRZ16W6-125-7X/6EG24N9ETK4/D3M - Bosch Rexroth R901381046

Nominal flow determines how much oil passes per percent of command value and therefore how finely an axis can be controlled. The pilot-operated proportional directional valve 4WRZ16W6-125-7X/6EG24N9ETK4/D3M works with a nominal flow of 125 l/min in size 16 and permits a maximum of 460 l/min.

Benefits

• Nominal flow 125 l/min, maximum flow 460 l/min, operating pressure up to 350 bar.
• Spool symbol W6, three switching positions on four ports.
• Version with pressure reducing valve, internal pilot oil supply and internal pilot oil return.
• Concealed auxiliary actuation, NBR seals for HL hydraulic fluid.
• Electrical control with external electronics, 24 VDC, connector 7-pole (6 + PE) to EN 175201-804, weight 12.04 kg.

Application

The valve controls axes that are positioned slowly and accurately, for example in test rigs and forming machines. The smaller nominal step spreads the command range across a narrower flow band. Control is provided by external amplifier electronics.
