Proportional Directional Valve 4WRTE25V350P-4X/6EG24K31/A1M - Bosch Rexroth R900972791

A cylinder that must travel fast and still position cleanly needs a characteristic with two characters. The 4WRTE25V350P-4X/6EG24K31/A1M solves that with a spool that carries a fine control range and handles 350 l/min nominal flow.

Benefits

• Spool with fine control range, small command values act flat, large ones act steep.
• 350 l/min nominal flow, up to 870 l/min maximum flow, operating pressure up to 350 bar.
• External pilot oil supply and external return, independent of the pressure in the main channel.
• Internal spool position feedback, plus/minus 10 V command value on the on-board electronics.
• Spool symbol V, three switching positions on four ports, ISO 4401-08-08-0-05.
• 18 kg, NBR seals, 7-pole connector (6 + PE), 24 VDC supply voltage.

Technical data

Application

The valve fits rapid and creep speed axes on presses, saws and test rigs. An external pilot circuit is a precondition and has to come from its own supply. For purely internal pilot supply there is a matching sister build.
