4.3.1 1” NPT CHECK VALVE INSTALLATION
1" NPT check valves are installed in the piping network when 20, 35, 60 or 100 lb. (8, 15, 27 or 44 L) containers
are grouped into a manifold or form a "Main & Reserve" system. The check valves have threaded bodies;
therefore, the piping leading into and exiting from each check valve must be threaded as well.
4.3.2 2" NPT CHECK VALVE INSTALLATION
2" NPT check valves are installed in the piping network when 125 or 215 lb. (51 or 90 L) Inverted Containers are
grouped into a manifold or form a "Main & Reserve" system. The check valves have threaded bodies; therefore,
the piping leading into and exiting from each check valve must be threaded as well.
4.3.3 3" NPT CHECK VALVE INSTALLATION
3" NPT check valves are installed in the piping network when 215, 375, 650 or 1000 lb. (87, 153, 267 or 423 L)
Large Capacity Containers are grouped into a manifold or form a “Main & Reserve” system. The check valves
have threaded bodies; therefore, the piping leading into and exiting from each check valve must be threaded as
well.
NOTE: The check valves must be installed with the flow arrow pointed in the same direction as the discharge. If
reversed, the system will not discharge properly.
NOTE:
The Check Valves must be installed with
the flow arrow pointing in the direction of
discharge. If reversed, the system will not
discharge properly.
