Abstract

A valve unit (1) for regulating the flow-rate of a fuel gas in dependence on the flow-rate of water, particularly for water-heaters, comprises a valve (11) for regulating the flow-rate of the fuel gas and a hydraulic turbine (2) which in turn includes a rotor (2a), the rate of rotation of which is associated with the flow-rate of water. The hydraulic turbine (2) is connected to the regulation valve (11) in order to regulate the flow-rate of the fuel gas in dependence on the flow-rate of water supplied to the turbine.
