What it is

The Honeywell V100U is a reverse flow insert intended for use with Honeywell T100, VT117 and VT200 valve ranges. It sits within the valve body and manages flow direction through the assembly. The insert is a service component, allowing the valve's reverse flow function to be maintained without replacing the complete valve.

Before you order

  • Confirm the valve on site is a Honeywell T100, VT117 or VT200 model before ordering.
  • Check the existing insert is removed and the valve body is clean and undamaged before fitting the replacement.
  • Verify the part number V100U against any documentation held for the valve assembly.
