What it is

The Potterton 2-Way Mod. Valve VVP459.20-4 is a two-way modulating valve for Potterton Commercial boiler applications. It controls water flow through the boiler circuit by varying the valve position rather than simply opening or closing it. The part is listed under Potterton Commercial boiler spares as a diverter valve and carries the manufacturer part number 5138656.

Before you order

  • Check the existing valve is marked VVP459.20-4 and that the boiler's part number reference is 5138656.
  • Confirm the installation is a Potterton Commercial boiler application.
  • Verify that a two-way modulating valve, not a two-port on/off valve, is what the circuit requires.
  • Compare the valve against the item being replaced before fitting.
