At Industrial Ancillaries our range of excess flow valves are available in a variety of pressure classes, materials and end connections. Excess flow valves (EFVs) are safety devices installed on gas or liquid lines to help prevent any leaks.
Designed to shut off the flow of gas or liquids when the flow rate exceeds a predetermined level. Flow valves can be used for both residential and industrial uses, to protect buildings from the potential dangers of a leak.
