Proportional Directional Valve 4WRTE25V350P-4X/6EG24ETK31/A1V - Bosch Rexroth R901044430

Every extra drilling in a manifold is a possible leak. The 4WRTE25V350P-4X/6EG24ETK31/A1V draws its pilot oil internally and returns it internally, at 350 l/min nominal flow and an operating pressure up to 350 bar.

Benefits

• Pilot oil entirely internal - neither X nor Y has to be machined into the manifold.
• 350 l/min nominal flow, with up to 870 l/min allowed through the valve.
• Symbol V with fine control range, three switching positions, four ports.
• Command value ±10 V on 24 VDC, on-board electronics, 7-pole connector (6 + PE).
• 17.78 kg on the ISO 4401-08-08-0-05 interface, FKM seals.

Application

This version is the simplest answer when retrofitting existing manifolds and in series machines with tight installation space. It expects a system pressure that keeps the pilot pressure available at all times. For plants with strongly fluctuating pressure a version with external pilot supply fits better.
