What it is
The Ariston 65114917 is a by-pass valve used in Ariston ONE and ONE NET series gas appliances. It regulates flow through the primary heating circuit, maintaining a minimum flow rate across the heat exchanger when system demand falls. It is fitted across the Alteas, Cares, CLAS, E-Combi, E-System and Genus ONE ranges.
