A valve outlet adapter connects the cylinder valve outlet to the discharge piping when a flexible
discharge hose is not used (see Figure 3-27 and Table 3-14).

connection in lieu of a valve outlet adapter.

Check Valve, 1/4-inch, P/N WK-264985-000
Check Valves are installed in sections of piping in main/reserve systems to prevent the
actuation of the reserve system when the main system is discharged.
1/4-inch check valves are installed in the pilot manifold to ensure the proper number of
cylinders are discharged (see Figure 3-28).
