Proportional Directional Valve 4WRZ32E1-360-7X/6EG24N9K4/D3M - Bosch Rexroth R901038780

Large installations often maintain pilot pressure in a separate circuit so that the pilot stage stays clear of the load cycle. The 4WRZ32E1-360-7X/6EG24N9K4/D3M is built for that and meters a 360 l/min nominal flow.

Advantages

• External pilot oil supply through X and external return through Y.
• Nominal flow of 360 l/min, up to 1600 l/min total flow.
• Pressure reducing valve in the pilot stage keeps pilot pressure limited and constant.
• Operating pressure up to 350 bar, spool symbol E1 with three switching positions.
• Concealed manual override, connection diagram ISO 4401-10-09-0-05.
• Weight of 43.55 kg, NBR seals, external amplifier electronics on 24 VDC.

Applications

It is used on presses, forging plants and test rigs with a central pilot pressure supply. Because both pilot paths run outside, the operating point survives heavy load changes. The manifold has to provide ports X and Y.
