Excess Flow valves also referred to as velocity check or seismic valves, are created to shut down immediately after a sudden surge of flow. An excess flow valve is basically an in-line valve via which liquid or pressurized gas flows in both the directions. They shut down after excessive discharge of vapor or liquid caused due to the breaking of the pipe system.
AEPL provides excess flow check valves in numerous pressure materials, classes, end connections and flange designs. These valves undergo stringent checks in a certified flow laboratory for performance and durability. The excess flow valve is basically a spring loaded check valve that closes only after flow of vapor or liquid via the valve produces sufficient force or flow for overcoming the strength of the spring that helps in keeping it open. The excess flow valves are utilized for different fluids as well as processes including excess flow check valve for lpg gas, anhydrous ammonia, butane, nitrogen air, anhydrous chlorine, water etc.
The valves are ideal for handling fluid components for oil and gas, chemical as well as petrochemical industries as well as water blast organizations.
