A ball valve is a form of quarter-turn valve which uses a hollow, perforated
and pivoting ball to control flow through it. It is open when the
ball's hole is in line with the flow and closed when it is pivoted
90-degrees by the valve handle.The handle lies flat in alignment
with the flow when open, and is perpendicular to it when closed,
making for easy visual confirmation of the valve's status.
Ball valves are durable, performing well after many cycles, and
reliable, closing securely even after long periods of disuse. These
qualities make them an excellent choice for shutoff and control
applications, where they are often preferred to gates and globe
valves, but they lack their fine control in throttling
The ball valve's ease of operation, repair, and versatility lend it
to extensive industrial use, supporting
pressures up to 1000 bar and temperatures up to 752 °F (500 °C),
depending on design and materials used. Sizes typically range from
0.2 to 48 inches (0.5 cm to 121 cm). Valve bodies are made of
metal, plastic, or metal with a ceramic; floating balls are often
chrome plated for durability. One disadvantage of a ball valve is
that they trap water in the center cavity while in the closed
position. In the event of a freeze, the sides can crack due to
expansion of ice forming. Some means of insulation or heat tape in
this situation will usually prevent damage.Another option for cold
climates is the "freeze tolerant ball valve". This style of ball
valve incorporates a freeze plug in the side so in the event of a
freeze up, the freeze plug ruptures, (acts as a sacrificial disk),
thus making for an easy repair. Now instead of replacing the whole
valve, just screw in a new freeze plug.
