Regulation valve

Regulation valve for gas cooking appliance powered by different types of fuel gas, natural gas (NG) or liquefied gas (LPG), comprising: a valve body (2), a rotary regulator member (6) housed in said valve body (2), said regulator member (6) comprising a plurality of inlet or outlet orifices which, through the rotation of said regulator member ( 6), can be successively faced with an inlet or outlet conduit (4), said inlet holes comprising a first inlet or radial outlet hole with a minimum flow rate (Qmin) corresponding to a first type of fuel gas, and a second radial inlet or outlet hole with a minimum flow rate (Qmin) corresponding to a second type of fuel gas, both inlet or outlet holes being arranged in contiguous angular positions and the second inlet or outlet hole being after the first hole input or output, and a drive shaft (7) that rotates in solidarity with the regulator (6), said drive shaft (7) comprising a projection (9) that determines the end of the angular travel of the regulating organ (6) when it interacts with end-of-travel stops, the valve body (2) also comprising a stop that acts as a stop end of travel for minimum flow (Qmin), said end of travel corresponding to the angular position of the regulator (6) in which the second inlet or outlet is facing the inlet duct (4), characterized in that the regulation valve (1) also comprises a stop element (10) that can be arranged in an active position in which it acts as a limit switch for the minimum flow rate (Qmin), leaving the regulating organ (6) in an angular position in which the first inlet or outlet hole faces the inlet duct (4), and in a rest position in which it does not act as a limit switch for minimum flow (Qmin).
