4.2.3 3" (80mm) VALVE CONNECTIONS
The 3" (80 mm) valve used on the 215, 375, 650 & 1000 lb. (87, 153, 267 and 423 L) containers has a 3" (80 mm)
groove machined into the outlet of the valve. The transition from the grooved outlet to pipe thread is made
through the use of an adapter nipple (supplied by Fike) that receives 3" (80mm) female pipe thread.
It is not necessary to supply a pipe union after the grooved coupling to facilitate removal of the container for
service or maintenance purposes.
IMPORTANT: Remove the Baffle Plate located inside the grooved coupling before connecting the discharge
piping to the container. The Baffle Plate is an anti-recoil device that must be installed whenever
transporting or handling charged containers that are not connected to the discharge piping.
4.3 MANIFOLDS
Discharge manifolds are used to connect multiple containers into a common supply and discharge piping network.
Simple two container manifolds may be used to create Main & Reserve systems without the need for redundant
piping systems. Larger multiples of containers are often manifolded to create larger bulk supplies of agent for
areas that require more than 1,045 lbs. (474 kg) of agent.
Manifolds are assembled in the field using approved fittings meeting the requirements of NFPA 2001. Larger
manifolds are commonly assembled using grooved fittings, but threaded, welded or flanged fittings can be used
as well. If grooved couplings are used, the gaskets must be lubricated with a non-petroleum base lubricant as
recommended by the fitting manufacturer.
Once the manifold is assembled and the containers connected, the manifold should not be supported by the
containers. The manifold piping should be secured with pipe hangers or brackets to support the manifold when
the containers are removed for service.
