1.11 CHECK VALVES
Check Valves are required for all HFC-227ea Containers connected in a manifold arrangement. NFPA 2001,
Section 2-1.3.5 requires all containers connected to a manifold have an automatic, mechanical, means of
preventing agent loss from an open leg of a manifold if the system is activated while a container is removed for
maintenance. Therefore, the Check Valves are required for each container in a manifold arrangement.
 1” NPT (25 mm) Check Valves (P/N 02-2980) are used for manifold arrangements, including connected
main-to-reserve systems, that utilize Small Capacity HFC-227ea Containers with the 1” (25 mm)
Discharge Outlet Valve.
 2” NPT (50 mm) Check Valves (P/N 02-4158) are used for manifold arrangements, including connected
main-to-reserve systems, that utilize Inverted HFC-227ea Containers with the 2-1/2” (65 mm) Discharge
Outlet Valve.
 3” NPT (80 mm) Check Valves (P/N 02-4157) are used for manifold arrangements, including connected
main-to-reserve systems, that utilize Large Capacity HFC-227ea Containers with the 3” (80 mm)
Discharge Outlet Valve.
