This disclosure relates generally to valves, and more particularly, to gas valve assemblies. In one example, a valve leakage test may be performed on a valve assembly including a valve body with a first valve and a second valve, where the valves may be positioned across a fluid path in the valve body with an intermediate volume between the valves. A pressure sensor may be in fluid communication with the intermediate volume and may sense a measure that is related to the pressure in the intermediate volume. The pressure sensor may communicate with a controller to determine a measure that is related to a pressure change in the intermediate volume and compare the measure that is related to a pressure change to a first and/or second threshold value. The controller may output a signal if the measure meets and/or exceeds the first and/or second threshold value.

Gas valve with valve leakage test

This disclosure relates generally to valves, and more particularly, to gas valve assemblies. In one example, a valve assembly may be configured to perform a valve proving test as part of an operational cycle of a combustion appliance coupled to the valve assembly. The valve assembly may include a valve body having a fluid path, first and second valve sealing members translatable between an opened position and a closed position, and one or more pressure sensors in fluid communication with an intermediate volume of the fluid path between the first and second valve sealing members. A valve controller may be in communication with the pressure sensor and may monitor a measure related to a pressure change rate in the intermediate volume. The valve controller may then output a signal if the measure related to a pressure change rate in the intermediate volume meets and/or exceeds a threshold value.

Gas valve with electronic valve proving system

This disclosure relates generally to valves, and more particularly, to gas valve assemblies. In one illustrative but non-limiting example, a valve assembly may include a valve body having an interior and an exterior, a valve or valve sealing member positioned in the valve body, a sensor element (e.g., a magnet and/or a ferrous core) secured relative to the valve sealing member and a sensor (e.g., a magnetic field sensor) positioned outside of the interior of the valve body. The valve sealing member may be movable between an opened position and a closed position, and the sense element may move with the valve sealing member. The sensor may be configured to detect a position of the valve sealing member and communicate that position to a valve controller.

Gas valve with electronic proof of closure system

This disclosure relates generally to valves, and more particularly, to gas valve assemblies. In one example, the valve assembly may include a valve body with an inlet port, an outlet port, and a fluid path extending between the inlet and outlet ports, one or more valves situated about the fluid path, one or more valve actuators for selectively moving respective valves, one or more sensors for sensing one or more parameters within the fluid path, and a controller secured relative to the valve body and in communication with the one or more sensors for determining one or more valve assembly conditions based on the one or more sensed parameters. Illustratively, the controller may be configured to communicate information from the valve assembly to a combustion appliance controller that is located remotely from the valve assembly through a communications interface of the controller and across a communications bus.

Gas valve with communication link

This disclosure relates generally to valves, and more particularly, to gas valve assemblies. In one illustrative but non-limiting example, a valve assembly may include a valve body, a valve situated in a fluid path of the valve body, a valve actuator for selectively moving the valve actuator, one or more sensors in communication with the fluid path, a controller secured relative to the valve body and in communication with the sensors, and memory operatively coupled to the controller. A user interface may be in communication with the memory and the controller and may be configured to receive a selection from a user for selecting one of two or more selectable options from the memory. The controller may compare sensed parameters to threshold values associated with the selected option. The user interface may have a lock on it to prevent tampering and to provide accountability.

The housing ( 2 ) circumferential wall ( 12 ) and first and second axially opposing end walls ( 14, 16 ) support bearing flanges with bearings ( 18 ) for the shaft ( 6 ). Two cooling fan impellers ( 20, 22 ) are connected to the shaft ( 6 ). An inner cooling fan impeller ( 20 ) positioned inside the housing ( 2 ) generates an inner cooling air circuit (A) inside the housing ( 2 ). An outer cooling fan impeller ( 22 ) provided outside the housing ( 2 ), generates an outer cooling air flow (B). The first end wall ( 14 ) is formed with a thermal conductivity of at least a specified value and has an outer cooling rib geometry ( 28 ) on its outer side facing the outer cooling fan impeller ( 22 ), and an inner cooling rib geometry ( 30 ) on its opposing inner side.
