Notes

Excess Flow Valves with a nominal gas flow rate of 2.5m³/hr in 20 and 25mm.

Excess Flow Valves are maintenance free and cannot be disabled by an external action. They can handle inlet pressures from 1.5kpa to 10kpa and are designed to shut of at 1.3 to 1.45 times the total flow rate of the pipeline they are installed into.
