Proportional Directional Valve 4WRZ32W8-520-7X/6EG24N9ETK4/D3M - Bosch Rexroth R900761494

Existing large manifolds rarely offer room for extra pilot lines. The 4WRZ32W8-520-7X/6EG24N9ETK4/D3M is piloted entirely internally and meters a 520 l/min nominal flow in size 32.

Advantages

• Internal pilot oil supply and internal return, no X and Y lines needed.
• Nominal flow of 520 l/min, up to 1600 l/min total at pressures reaching 350 bar.
• Pressure reducing valve in the pilot stage keeps pilot pressure limited.
• Spool symbol W8, three switching positions, four ports to ISO 4401-10-09-0-05.
• Concealed manual override for commissioning and maintenance.
• Weight of 43.58 kg, NBR seals, driven by external amplifier electronics.

Technical data

Applications

The version is intended for retrofits on large manifolds and for plants with little room on the valve carrier. Pilot pressure must be present at port P throughout the cycle. Back pressure in the tank line has to be limited.
