Description

Six cylinder sizes are available: 10, 20, 40, 70, 125, and 200 lb. capacities. They can be filled as shown below:

All sizes are charged with FM-200TM 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. Cylinder and valve assemblies, FM-10H, 20OH, 40H and 70H are furnished with an internal siphon tube having a urved 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 1% inch unified thread outlet; the 200 Ib. 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 pilt 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 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.

Valve Controls

All valve sizes are threaded to accept the same set of valve controls described below:

A. Electric Solenoid Valve •
The Solenoid valve is normally closed and opens upon electric energy being applied, thus relieving the pressure above the valve piston and causing the cylinder valve to open. The solenoid valve has a swivel nut for mechanical connection to the cylinder valve. For electrical connection it is furnished with 18″ pigtails which are led through flexible metallic conduit to allow convenient removal of the solenoid valve from the cylinder valve when servicing.
B. Manual Control Head – Local •
Moving the actuating lever through 90° causes a pin to depress and open the pilot check on the valve and releases FM-200TM pressure above the valve piston.
C. Manual Control Head – Remote •
Same actuation as the local manual, except the lever is controlled remotely by a 1/16 inch diameter stainless steel pull cable enclosed in ½ inch E.M.T. with corner pulleys at each change in direction. The cable terminates in a remotely located pull box.
D. Pressure Actuator •
The pressure actuator replaces the local and remote control heads on the valve. It contains a piston of sufficient area to provide the necessary force to open the pilot check when pressure from the FM-200TM discharge of a master cylinder is applied through 5/16″ tubing. The pressure actuator is used on pressure operated slave cylinders which are to be released simultaneously with the master cylinder. One master cylinder can be used to pressure operate up to a maximum of four slave cylinders. If more than four cylinders are required, up to 15 may be pressure operated using a nitrogen pilot cylinder. All cylinder valves have a pressure actuation outlet port. It opens into the same space as the valve outlet and is under pressure only while the valve is discharging. The port has a 1/8″ pipe thread which is fitted with a pipe plug. The pipe plug is removed when the port is to be used, and a master cylinder adapter kit is installed. The tubing or pipe is connected to the outlet of the adapter kit and run to the pressure actuators on the slave cylinders.
E. Combination Pressure Actuator and Manual Control
A special pressure actuator is also available to which either a local or remote type manual control head can be attached. It is used when both pressure actuation and manual control is required for the same cylinder
