Check Valves

Check valves are a means of preventing a reverse flow and are to be installed in the gas line where air ix mixed with fuel gas prior to combustion, as with gas/air brazing torches, jewelery torches, and many types of industrial burners. Check valves should also be fitted in the corresponding air line where there is a possibility of the pressure falling below that of the gas, a condition frequently encountered when starting up. Larger sizes of check valves can be fitted on the outlet side of the gas meter to give general protection, and smaller sizes should be fitted on the inlet pipe to any appliance where gas and air are mixed.
