Abstract: Gas flow control valve 3, wherein the gas flow control valve 3 comprises a housing 11 with a gas inlet 10, a valve seat 6 arranged in the housing 11, a valve body 5 assigned to the valve seat 6, wherein the valve body 5 is held by an upper spring and a lower spring and is centered by means of a diaphragm 26, and a gas outlet 12 which is positioned downstream of the valve body 5 and which is provided in the housing 11, wherein the valve body 5 is arranged in the valve seat 6 so as to be movable in a first movement direction 17 in order to form a controllable cross section of a passage opening 25 for the passage of gas, wherein the gas flow control valve 3 comprises an adjustable diffuser 13.

Abstract: A gas control valve (1) has a central module (40), a control module (20) and a sensor module (30). Gas can flows through the central module (40) from a valve inlet (41) to a valve outlet (42). The control module (20) is directly on the central module (40) and controls a flow of the gas through the central module (40). A throttle element (23) is fluidically arranged between the valve inlet (41) and the valve outlet (42). The sensor module (30) is arranged directly on the central module (40) and has at least one sensor (31, 32) in operative connection with the gas flowing through the central module (40) through a gas inlet (44) fluidically arranged between the throttle element (23) and the valve outlet (42). In order to control the pressure, it detects a pressure difference between the gas flowing through the central module (40) and air having a reference pressure.
