Potterton Titanium Gas Valve – Pre-Owned | Part Nos. 720301001 / 720514301

Ignition faults, unstable flame behaviour, or repeated boiler lockout in a Potterton Titanium, Gold, Promax, Apollo, or Heatmax boiler are common signs of a failing gas valve. This component regulates gas delivery to the burner — when it wears, gas flow becomes unreliable and the boiler cannot maintain safe combustion. The Potterton Titanium Gas Valve (Part Nos. 720301001 / 720514301) is the pre-owned direct replacement, covering one of the widest Potterton compatibility ranges available — spanning Titanium 24/28/33/40, Gold HE/HEA Combi, Gold System, Heatmax Combi, Apollo, Promax Combi, Promax System, and Promax HE Store series including ERP and serial number variants.

This pre-owned unit is quality-checked and verified for correct operation before dispatch. Supplied with a 6-month warranty.
