Worcester Greenstar CDI Gas Valve – Refurbished | Part No. 87161165150 / 87182213470

Ignition failure, unstable flame, or complete boiler lockout in a Worcester Greenstar CDI or Highflow boiler is a strong indicator of a failing gas valve. This component controls the precise flow of gas to the burner — when it deteriorates, it can no longer regulate combustion accurately, resulting in unsafe or unreliable boiler operation. The Worcester Greenstar CDI Gas Valve (Part Nos. 87161165150 / 87182213470) is the fully refurbished direct replacement, restoring precise gas regulation and safe, stable heating performance across one of Worcester's most widely installed CDI model ranges.

This is a fully refurbished Worcester Bosch component, removed from a working boiler and quality-checked by our experienced engineering team to the highest standard before dispatch. It covers an extensive compatibility range including Greenstar Combi 25 to 42 CDI, CDI System and Conventional, 29/34/38/42 CDI Classic, CDI Classic ERP, FS 30/42 CDI, and Highflow 440/550 CDI models — including LPG variants. Supplied with a 12-month warranty.
