CHECK VALVE SET TORCH

REVERSE FLOW
CHECK VALVES
For torch and regulator applications,
Western Check Valves guard against
danger caused by plugged tips, overpressurizing
or incorrect startup
procedures. Proper Check Valve
installation helps prevent accidents
caused by gases mixing in hoses,
regulators or cylinders.
NOTE: CHECK VALVES DO NOT
STOP FLASHBACKS. SEE PAGE
