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 typically causes the boiler to produce either heating or hot water — but not both simultaneously. As the valve wears or seizes internally, it can no longer switch hydraulic flow correctly between the central heating and domestic hot water circuits. The Biasi Garda M90F 24S Boiler Diverter Valve (Part No. BI1141500) is the correct OEM-specification replacement for a wide range of Biasi M90 series boilers, restoring full hydraulic switching and dual-mode 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 control at a fraction of the cost of a new valve.
