Proportional Directional Valve 4WRZE25W8-325-7X/6EG24N9EK31/F1D3M - Bosch Rexroth R900753993

In blow moulding the calmness of the closing movement decides the wall thickness of the part. The 4WRZE25W8-325-7X/6EG24N9EK31/F1D3M meters 325 l/min nominal flow under position control, feeds its pilot stage internally and drains it to the outside.

Benefits

• Internal pilot oil supply with external return keeps pilot pressure calm.
• Nominal flow of 325 l/min closes the mould briskly, plant maximum 870 l/min.
• A 4 to 20 mA current command works regardless of voltage drops along the cable.
• Spool symbol W8, 3 switching positions, 350 bar operating pressure, ISO 4401-08-08-0-05.
• 4 ports, NBR seals, 24 V DC, weight 20.99 kg, UKCA to SI2016/1091.

Applications

The valve moves clamping units, blow pins and take-out axes in plastics processing. Comparable tasks appear on thermoforming lines and laminating presses. A pressure reducing valve in the pilot circuit keeps pilot pressure independent of the 350 bar system pressure.
