Excess Flow valves are also known by other names such as;
.
Flow Fuse
Flow Limiter
Flow Check Valves
Velocity Check Valves
Line Burst Control Valves
Pipe-break valve
.
The design concept of the valve is that the internal disc is held open by a spring. When the flow of the fluid exceeds a certain preset limit the valve disc closes and shuts of the flow.
This can be the case In the event of a vessel rupture, disconnection, or pipe-line break. In this event the pressure will drop, the flow will surge exceeding the spring load limit, and the valve will close creating a safe situation.
.
There are many applications for Excess flow valves but main installed base of our excess flow valves is in bullet storage tanks.
