A valve seat of the valve cooperates with the passage opening to regulate the flow of gas through the valve. An electrical actuator assembly is operatively coupled with the valve seat to regulate the flow of gas through the valve. In one implementation the gas enclosure is at least in part sealed by an elastic sealing member that is pressed upon by a printed circuit board that electrically connects the actuator assembly to an exterior of the gas valve. ## Claims ### Claim 1 A gas valve comprising a valve body having a gas enclosure with a gas inlet, a gas outlet and a passage opening situated between the gas inlet and the gas outlet; a valve member comprising a valve seat that is moveable in relation to the passage opening to regulate a gas flow between the gas inlet and the gas outlet; an electrical actuator assembly disposed within the gas enclosure, the electrical actuator assembly operatively connected to the valve member and adapted to impart movement to the valve member to regulate the flow of gas between the gas inlet and the gas outlet; a printed circuit board situated adjacent an exterior of the valve body and electrically coupled to the electrical actuator assembly by at least one electrical connector, the printed circuit board having one or more electrical traces that couple the at least one electrical connector to a connection area of the printed circuit board, the connection area being accessible from an exterior of the valve body; and an elastic sealing member situated between the printed circuit board and the gas enclosure, the elastic sealing member having a first surface facing toward the gas enclosure and an opposite second surface facing toward a first surface of the printed circuit board, the first surface of the printed circuit board pressing against the second surface of the elastic sealing member to form a gas-tight seal between the gas enclosure and the exterior of the valve body. ### Claim 2 (depends on 1) A gas valve according to claim 1, wherein the elastic sealing member comprises at least one hole and the printed circuit board comprises at least one respective hole, the at least one electrical connector extending through the at least one hole of the elastic sealing member and the at least one respective hole of the printed circuit board and being connected to a second surface of the printed circuit board opposite the first surface. ### Claim 3 (depends on 2) A gas valve according to claim 2, wherein at least a portion of the elastic sealing member extends through the at least one hole of the printed circuit board surrounding the at least one electrical connector. ### Claim 4 (depends on 1) A gas valve according to claim 1, wherein the connection area corresponds with an extension of the printed circuit board. ### Claim 5 (depends on 4) A gas valve according to claim 4, wherein a portion of the valve body at least partially covers the connection area. ### Claim 6 (depends on 4) A gas valve according to claim 4, wherein the valve body comprises a housing accessible from the exterior of the valve in the area of the connection area, the housing adapted to receive a connector to be connected to the connection area. ### Claim 7 (depends on 1) A gas valve according to claim 1, wherein the printed circuit board is made of a metal. ### Claim 8 (depends on 7) A gas valve according to claim 7, wherein the printed circuit board is made of aluminium. ### Claim 9 (depends on 1) A gas valve according to claim 1, further comprising a sensor disposed within the gas enclosure, the sensor electrically coupled to the connection area of the printed circuit board via one or more signal conduction paths running through the printed circuit board. ### Claim 10 (depends on 9) A gas valve according to claim 9, wherein the printed circuit board has a first signal conduction path for transmitting signals generated by the sensor to the connection area and a second signal conduction path for transmitting signals from the connection area to the sensor. ### Claim 11 (depends on 1) A gas valve according to claim 1, wherein the printed circuit board is electrically coupled to the electrical actuator assembly by first and second electrical connectors, the first electrical connector coupled to a first electrical trace of the printed circuit board that couples the first electrical connector to the connection area, the second electrical connector coupled to a second electrical trace of the printed circuit board that couples the first electrical connector to the connection area. ### Claim 12 A gas valve comprising a first valve body having a gas enclosure with a gas inlet, a gas outlet and a passage opening situated between the gas inlet and the gas outlet; a second valve body having an air enclosure; a valve member comprising a valve seat that is moveable in relation to the passage opening to regulate a gas flow between the gas inlet and the gas outlet; an electrical actuator assembly disposed within the air enclosure, the electrical actuator assembly operatively connected to the valve member and adapted to impart movement to the valve member to regulate the flow of gas between the gas inlet and the gas outlet; a printed circuit board situated between the gas enclosure and air enclosure and having a first surface facing toward the air enclosure and an opposite second surface facing toward the gas enclosure, the printed circuit board electrically coupled to the electrical actuator assembly by at least one electrical connector, the printed circuit board having one or more electrical traces situated on the first surface that couples the at least one electrical connector to a connection area of the printed circuit board, the connection area being accessible from an exterior of the gas valve;
