Proportional Directional Valve 4WRZE16E180-7X/6EG24N9EK31/A1D3M - Bosch Rexroth R901404455

Pilot operated valves react sensitively to excessive control pressure. The 4WRZE16E180-7X/6EG24N9EK31/A1D3M therefore carries a pressure reducing valve in the pilot circuit, takes control oil internally, drains through Y to the outside and controls 180 l/min nominal flow at up to 350 bar.

Benefits

• Integrated pressure reducing valve in the pilot circuit, keeping control pressure unaffected by system pressure up to 350 bar.
• 180 l/min nominal flow in size 16 against a series maximum flow of 460 l/min.
• Internal pilot oil supply with external return through Y, free of back pressure in the T port.
• Concealed auxiliary actuation for commissioning without an electrical signal.
• Plus or minus 10 V command, spool symbol E, NBR seals, weight 12.1 kg, UKCA conformity.

Applications

The valve is used on presses, on injection moulding machines and on lifting axes whose system pressure goes beyond the design value of the pilot stage. Concealed auxiliary actuation lets the axis be moved by hand during commissioning. Spool position is fed back electrically.
