All sizes are charged with FM-200
TM
and pressurized with nitrogen
to 360 psig at 70°F. They are manufactured, tested, and marked in
accordance with D.O.T. specifications: 4BA500 or 4BW500 for the
various sizes. The 125 and 200 lb. cylinders are fitted with lifting
lugs for convenience in handling.
furnished with an internal siphon tube having a curved lower end
which permits mounting horizontally. Cylinder bracketing is
available for vertical, horizontal and wall mounting.
Cylinder Valves
The 10, 20, 40, 70 and 125 lb. size cylinders use a valve with a 1½
inch unified thread outlet; the 200 lb. size uses a valve with a 2 inch
unified thread outlet. Both valves are of a pressure-seated high
flow rate design in order to meet the rapid discharge time specified
in NFPA 2001. Both have a brass body, a brass piston with resilient
seat, a pressure releasing pilot check assembly for manual and
pressure actuation, a safety disc assembly, a pressure guage, and
a connection port with a built-in check valve for attachment of an
electric solenoid valve which relieves the pressure above the
piston and permits the piston to travel upward, thus fully opening
the valve and permitting the FM-200
TM
to discharge through the
outlet. The discharge outlet is fitted with an anti-recoil plug which is
a safety device to prevent movement of the cylinder in the event of
discharge while the cylinder valve is not connected to the piping
system and the cylinder is not securely fastened to a solid
structure.
