What it is

The Valor expansion vessel Z1-1100000806 is a sealed pressure vessel used in Valor Group boiler installations. It absorbs the volumetric expansion of water as the heating circuit warms, limiting pressure rise across the system. The part carries the manufacturer reference Z1-1100000806 and the catalogue number 97392032.

Signs this part needs replacing

  • System pressure rises sharply when the boiler heats up and falls again once it cools.
  • The pressure relief valve discharges water during normal operation.
  • Pressure is lost repeatedly and the system needs frequent topping up.
  • Water or moisture is present at the vessel's air valve connection.
  • The vessel feels heavy or full of water when disconnected and checked.

Before you order

  • Confirm your appliance model against the manufacturer's parts list.
  • Check the existing vessel's part number matches Z1-1100000806.
  • Verify the system volume and required vessel capacity before fitting.
  • Depressurise and isolate the appliance before removal or installation.
