What it is

The Honeywell VXE25B6.3MFS is a 3-way valve (3WVS) with external connection, DN25 nominal size, PN16 pressure rating, Kvs 6.3 flow coefficient, and modulating (Mod) control. It is intended for flow regulation in hydronic heating or cooling circuits. The Fs suffix denotes a specific factory configuration; consult the valve datasheet for its precise function.

Before you order

  • Confirm DN25, PN16, and Kvs 6.3 match the system requirements.
  • Verify the external connection is compatible with the pipework.
  • Ensure a modulating (Mod) actuator is suitable for this valve.
  • Check that the Fs configuration is correct for the intended application.
