Glowworm Ultracom Gas Valve – Pre-Owned | Part No. 2000802664 / 801649

A gas valve that is failing in a Glowworm Ultracom or CXI boiler will typically cause ignition errors, unstable flame, inconsistent heating output, or complete lockout. This component controls gas flow to the burner and is essential for safe, regulated combustion. When it deteriorates, the boiler cannot maintain stable performance. The Glowworm Ultracom Gas Valve (Part Nos. 2000802664 / 801649) is the direct pre-owned replacement, restoring precise gas regulation across the Ultracom CX, CXI, HXI, and SXI series, as well as compatible Glowworm 24CXI and 30CXI models.

This pre-owned unit is sourced from a fully functioning boiler and tested by our experienced engineering team to verify safe, reliable operation before dispatch. Minor cosmetic marks may be present, but all functional performance is confirmed prior to sale. Supplied with a 6-month warranty.
