Proportional Directional Valve 4WRZE25W6-325-7X/6EG24ETK31/F1V - Bosch Rexroth R987099281

A 4 ... 20 mA command value stays diagnosable when a cable breaks, because the current then drops to zero. The 4WRZE25W6-325-7X/6EG24ETK31/F1V uses exactly that signal range and meters 325 l/min nominal flow, up to 870 l/min when required. The pilot stage works without a pressure reducing valve and is both fed and relieved internally.

Benefits

• Command value range 4 ... 20 mA, so a broken cable is visible in the signal itself.
• Nominal flow 325 l/min with a maximum flow rate of 870 l/min.
• Pilot stage without a pressure reducing valve, with pilot supply and return routed internally.
• Spool symbol W6 with three switching positions and an operating pressure of up to 350 bar.
• FKM seals and a valve weight of 20.58 kg on mounting pattern ISO 4401-08-08-0-05.

Technical data

Application

The valve controls large cylinders and hydraulic motors in presses, rolling mills and test plants. Mineral oil of class HL is the intended fluid, and the FKM seals widen fluid compatibility. The electrical connection is a 7-pole plug to EN 175201-804.
