Abstract (en)
A gas boiler valve assembly comprises a gas path (3) extending between a gas inlet opening (4) and a gas outlet opening (5) to a burner, adjustably intercepted by a disk (17) operated by respective membrane control means (21). Advantageously, the valve assembly comprises control devices (22, 23) capable of driving in a broad modulation range the membrane control means (21) in response to the air flow fed to the burner and, respectively, to an electrical signal proportional to the thermal power required to the burner. <MATH>
