Proportional Directional Valve 4WRZE10W8-50-7X/6EG24N9K31/F1V - Bosch Rexroth R901258597

On a calender the roll loading decides thickness and finish of the web. The 4WRZE10W8-50-7X/6EG24N9K31/F1V meters 50 l/min rated flow at 315 bar maximum for that and works from a current command value that fits into existing process control equipment.

Benefits

• 50 l/min rated flow, flow up to 170 l/min, operating limit 315 bar.
• Current command value 4...20 mA, fed straight from existing analogue outputs.
• Spool symbol W8, three switching positions, size 10, port pattern ISO 4401-05-05-0-05.
• External pilot oil supply and external pilot oil return, without a pressure reducing valve.
• Concealed manual override, 7.92 kg, FKM seals, HL fluid.

Application

Calenders, coating lines and winding stations in paper and film processing use this control for nip force. Because pilot oil is supplied externally, the pilot stage stays fed while working conditions are lowered. The same axis with a voltage signal is served by the A1 build.
