GasValve

Gas valves permit or prevent the flow of gas using ball, gate, plug, or other mechanisms. Valves are pressure-rated by the American National Standards Institute (ANSI). Valves designated as ‘key’ valves are critical to modeling and analysis. Indicating key valves is a Department of Transportation (DOT) requirement. Key valves may need to be inspected more often.

GasValve inherits characteristics from the abstract class GasDevice. Any model names assigned to this class should be assigned to GasValve as well.

Gas tracing requires the VALVE class model name.
