Cylinder
:
The welded seam steel cylinders are
A
manufactured to the requirements of the Depart-
ment of Transportation (DOT) for compressed gas
and have internal neck threads for cylinder valve
connection.
Dip Tube
: A threaded dip tube extends from the cyl-
B
inder valve down to within approximately 1-1/2 in.
(38 mm) of the bottom of the cylinder.
Cylinder Valve
: A pressure differential type cylinder
C
valve having a forged brass body is attached to the
cylinder neck and serves to control the flow of FM-
200 from the cylinder.
The valve is secured to the cylinder by means of 4.5-
12UN-2A screw threads and is sealed by a cylinder O-
ring. A synthetic rubber seat is attached to a steel
seat retainer, which is screwed into the bottom of
the valve. The seat retainer also supports the dip
tube.
The cylinder valve has six connections, as follows:
Manual-Pneumatic Actuator Connection
: This is a
1
threaded connection housing a check valve and
serves as the attachment point for the manual-
pneumatic actuator.
Pressure Gauge/Solenoid Pilot Valve Assembly
2
Connection
: This is a threaded connection housing
a check valve and serves for the attachment of:
Solenoid pilot valve assembly (with pressure
gauge) for pilot cylinders.
Pressure gauge assembly for all other system
cylinders.
Pneumatic Actuator Connection
: This is a threaded
3
connection housing a check valve located on top of
the cylinder valve. It serves as an attachment point
for the pneumatic actuators.
Safety Disc Connection
: Two frangible safety discs
4
are located on opposite sides and serve to protect
the cylinder against excessive internal pressure. The
discs are designed to burst in a range of 850 psi to
1000 psi (5860 kPa to 6895 Kpa).
Discharge Connection
: This connection (2 in. nomi-
5
nal pipe size) (51 mm) is in the form of an outlet fit-
ting that threads into the valve body and is sealed
with an O-ring. The exposed end is grooved for at-
tachment of grooved fittings (Victualic, etc.). The
outlet fitting can be removed for replacement if
necessary.
COMPLETER KIT
Either a primary or slave completer kit is required to
complete the installation of each FM-200 cylinder. The
components included in the primary and slave completer
kits are detailed in the following chart.
