Proportional Directional Valve 4WRZ32E1-360-7X/6EG24N9TK4/D3M - Bosch Rexroth R900618472

Large manifolds often run a shared pilot pressure line while the tank gallery works without noticeable counter pressure. The 4WRZ32E1-360-7X/6EG24N9TK4/D3M is designed for these conditions and meters a 360 l/min nominal flow.

Advantages

• External pilot feed through X from the shared pilot pressure grid.
• Internal return to T, so the Y port on the manifold is dropped.
• Nominal flow of 360 l/min, up to 1600 l/min total, operating pressure up to 350 bar.
• Pressure reducing valve in the pilot stage for constant pilot pressure.
• Spool symbol E1, three switching positions, connection diagram ISO 4401-10-09-0-05.
• Weight of 43.41 kg, NBR seals, concealed manual override.

Technical data

Applications

The valve is used on collector manifolds of large plants with a central pilot pressure supply. An internal return cuts the number of fittings on the manifold. Back pressure in the tank line has to be limited.
