F150 & F300 2-Piece Ball Valves
Valves & Controls
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 floating" ball principle. The ball is not fixed, but is free to move with
the line pressure. As a result, these valves are capable of tight shut-off with the flow 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 turning the valve end-for-end in the pipeline.
USE
Maximum results and long life of valves can be maintained under normal working conditions and in
accordance with pressure/temperature date chart.
MANUAL OPERATIONS
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.
AUTOMATED OPERATION
Valves with actuators should be checked for actuator-valve alignment. Angular or linear misalignment will
result in high operational torque.
GENERAL INFORMATION FOR ON-SITE INSTALLATION
The valve may be fitted 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.
DISASSEMBLY & CLEANING PROCEDURES
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.
1. Remove the line pressure
2. Place the valve in half-open position and flush the line to remove any hazardous material from valve.
3. All persons involved in the removal and disassembly of the valve should wear the proper protective
clothing, such as face shield, gloves, apron, etc.
As shipped from the factory, valves contain a silicone based lubricant. This is for break-in and may be
removed, if it is objectionable for a particular application, by disassembling and solvent washing.
