Proportional Directional Valve 4WRLE25V400L-4X/MPT/24A1 - Bosch Rexroth R901478128

When valve and amplifier share the same machine frame, a voltage command is enough. The 4WRLE25V400L-4X/MPT/24A1 uses plus minus 10 V, routes pilot oil internally in supply as well as return and provides 400 l/min rated flow at 350 bar.

Benefits

• Command value plus minus 10 V, connects straight to common analogue outputs of a controller.
• Fully internal pilot circuit, which shortens assembly time on the valve block.
• Linear characteristic curve, spool symbol V, 3 switching positions, internal position feedback.
• 400 l/min rated flow, 1250 l/min maximum flow, 350 bar operating pressure.
• ISO 4401-08-08-0-05, CE marked, NBR seals, 24 VDC, 19.44 kg.

Applications

Typical duties are clamping units of injection moulding machines, feed axes on saws and lifting gear at medium flow. Internal return assumes a tank line without noticeable back pressure. Where returns are shared, the version with a Y port is the safer choice.
