Proportional Directional Valve 4WRZ32E1-520-7X/6EG24N9TK4/D3M - Bosch Rexroth R900740262

Where a regulated pilot pressure supply exists while the tank gallery runs without counter pressure, this combination fits. The 4WRZ32E1-520-7X/6EG24N9TK4/D3M uses an external feed and an internal return at a 520 l/min nominal flow.

Advantages

• External pilot feed through X, pilot pressure comes from a regulated source.
• Internal return to T, so a Y port on the manifold is dropped.
• Nominal flow of 520 l/min, up to 1600 l/min total flow.
• Pressure reducing valve in the pilot stage, operating pressure up to 350 bar.
• Spool symbol E1, three switching positions, connection diagram ISO 4401-10-09-0-05.
• Weight of 43.66 kg, NBR seals, concealed manual override.

Applications

The valve is used on large positioning axes served by a central pilot pressure grid. The internal return saves a line but assumes a largely unpressurised tank gallery. Control is handled by external amplifier electronics on 24 VDC.
