Installation, Operation & Maintenance
Full-Flo Series Ball Valve
Model: F150 / Model F300
Printing Date 2014/04
F150 and F300 2-Piece Ball Valves
DESIGN
Split body, two-piece construction, allows ease in maintenance of valve ball and seat, without special tools. This line of valves
utilizes the “free fl oating” ball principle. The ball is not fi xed, but is free to move with the line pressure. As a result, these valves
are capable of tight shut-off with the fl ow in either direction or dead-ended, regardless of the position of the valve in the line. The
downstream seat, which is opposite the pressurized side of closed valve must carry the load exerted by the line pressure on the ball,
while the upstream seat is subject to little load or wear. For this reason, it is sometimes possible to increase useful seat life by turn-
ing the valve end-for-end in the pipeline.
Maximum results and long life of valves can be maintained under normal working conditions and in accordance with pressure/tem-
perature chart.
The opening and closing of the valve is done by turning the handle a ¼ turn (90 degrees)
The valve in open position: the handle is in-line with the valve or pipeline.
The valve in closed position: the handle is across or perpendicular to pipeline.

GENERAL INFORMATION FOR ON-SITE INSTALLATION
DISASSEMBLY & CLEANING PROCEDURES
Valves with actuators should be checked for actuator-valve alignment. Angular or linear misalignment will result in high opera-
tional torque.
The valve may be fi tted in any position on the pipeline. Before installing the valve, the pipe should be clean of dirt, burrs and
welding residues, or you will damage the seats and ball surface.
If the valve has been used to control hazardous media, it must be decontaminated before disassembly. It is recommended that the
following steps are taken for safe removal and reassembly.
As shipped from the factory, valves contain a silicone based lubricant. This is for break-in and may be removed, if it is objection-
able for a particular application, by disassembling and solvent washing.
Remove the line pressure
Place the valve in half-open position and fl ush the line to remove any hazardous material from valve.
All persons involved in the removal and disassembly of the valve should wear the proper protective
clothing, such as face shield, gloves, apron, etc.

Flo-Tite can not anticipate all of the situations a user may encounter while installing and using valves. The user must know and
follow all applicable industry specifi cations on the safe installation and use of these valves. Mis-application of the product may
result in injuries or propery damage. Refer to product catalogues, brochures and IOM for additional product safety information or

Keep hands and objects away from the valve ports at all times. Actuated valve could be accidentally operated, resulting in
serious injury or damage.
Before removing a valve from the line always make sure the line has been depressurized and drained.
Utmost caution must be taken when handling a valve that has toxic, corrosive, fl ammable or a contaminant media fl owing
through its pipeline.
The following safety precautions are recommended when dismantling valves with hazardous media:
A. Wear eye shield, protective headgear, clothing,
gloves and footwear.
B. Have available running water.
C. Have a suitable fi re extinguisher when media is
fl ammable.
Do not try to operate a valve that exhibits any sign of leakage. Isolate the valve and repair or replace it.
