Biasi Garda M90F 24S Boiler Diverter Valve – Refurbished | Part No. BI1141500

A stuck or failed diverter valve in a Biasi Garda, Riva, or Parva boiler prevents the hydraulic circuit from switching correctly between central heating and domestic hot water — leaving you with either heating or hot water, but not both on demand. The Biasi Garda M90F 24S Boiler Diverter Valve (Part No. BI1141500) is the correct OEM-specification replacement for the full Biasi M90 series range, restoring accurate hydraulic switching and dual-mode boiler operation.

This is a professionally refurbished genuine Biasi component. Each unit is stripped, cleaned, inspected, and function-tested to original manufacturer specifications before dispatch — providing dependable hydraulic performance at a fraction of the cost of a new valve.
