Proportional Directional Valve 4WRZ16W6-150-7X/6EG24N9ETK4/V - Bosch Rexroth R900946595

On an axis where neither an external pilot supply nor a separate return line is to be routed, the version with internal pilot oil supply and return saves piping. The pilot-operated proportional directional valve 4WRZ16W6-150-7X/6EG24N9ETK4/V meters a nominal flow of 150 l/min in size 16 and permits a maximum of 460 l/min.

Benefits

• Nominal flow 150 l/min, maximum flow 460 l/min at 350 bar operating pressure.
• Internal pilot oil supply and internal pilot oil return, no additional pilot lines needed.
• Spool symbol W6, three switching positions, four ports, without pressure reducing valve.
• FKM seals for HL hydraulic fluid, connection diagram ISO 4401-07-07-0-05.
• Electrical control with external electronics, 24 VDC, connector 7-pole (6 + PE) to EN 175201-804, weight 11.3 kg.

Technical data

Application

Typical installations are presses, auxiliary rolling mill drives and test rigs with continuous position or speed setpoints. Since the pilot stage is supplied internally, sufficient pilot pressure has to be present in the main line. The setpoint is handled by external amplifier electronics.
