06 Excess Flow Valves

05 Valves » 06 Excess Flow Valves

These valves are designed for liquid or vapor fill or withdrawal and for vapor equalization in containers or line applications. They are intended to close when the liquid or vapor passing through the hose or the piping system exceeds the prescribed flow rate.  


Once the flow exceeds the valve setting, the valve closes and will remain closed until the system equalizes. Once the pressures on both sides have equalized through the built-in equalizing passage, the valve automatically opens the valve.
