How does an excess flow valve work
WebThe excess- flow valve is designed to interrupt gas flow if a certain flowrate is exceeded. It is an important safety device that can stop gas from flowing should a leak occur. It is usually available for a number of different flow ranges depending on user requirements. WebFeb 6, 2009 · A flow divider can split flow equally, unequally, and into more than two paths. One design maintains a constant flow for one outlet and directs any excess flow to a second outlet. Figure 11-1 pictures the ISO symbol for a flow-dividing valve. While the ISO symbol shows the function of the valve, it does not indicate which design it is.
