Proportional Directional Valve 4WRZE10W6-50-7X/6EG24ETK31/F1D3V - Bosch Rexroth R901204400

Changing a screen on a running extruder must not let melt conditions jump. The 4WRZE10W6-50-7X/6EG24ETK31/F1D3V drives the cylinder at 50 l/min rated flow and 315 bar maximum, and spool symbol W6 gives the overlap suited to axes that have to block in centre position.

Benefits

• Spool symbol W6 with three switching positions for axes that should block at centre.
• 50 l/min rated flow, flow up to 170 l/min, operating limit 315 bar.
• Internal pilot oil supply and internal pilot oil return, plus a pressure reducing valve in the pilot stage.
• Current command value 4...20 mA into the on-board electronics, 24 VDC supply.
• Size 10, port pattern ISO 4401-05-05-0-05, 9.16 kg, FKM seals for HL fluid.

Application

Screen changers, melt pump drives and calender gaps in plastics processing work with this control. The blocked centre of symbol W6 keeps the cylinder in place if the signal fails. For an axis run on a voltage signal, the A1 build applies.
