▶️Introduction
Ball valves obtain their name from the type of valve disc used. Ball valves are ¼ turn valves and are suitable for stopping and starting flow. Ball valves are not suitable for throttling/regulating flow.
Operation
The ball of the valve has a hole drilled through the middle. When the hole is in line with the valve body and connected piping, the valve is in the open position. When the hole is perpendicular with the valve body, the valve is in the closed position. The handle (actuator) indicates the position of the valve (in-line = open, perpendicular = closed).
Advantages
The pressure drop through the ball valve is vey low.
The ball valve is fast acting.
The seat to disc fit is tight and thus the chances of leakage/passing are reduced.
The valve is cheap to manufacture and maintain.
Ball valves require no lubrication.
Only a small amount of torque is required to actuate the valve and gearboxes can be used to make actuation of larger valves easier (lower torque on the primary side required).
Disadvantages
The ball valve is poorly suited to throttling applications.
The ball valve seat is often constructed from plastic or polymer materials, this makes the valve ill suited to high temperature applications.
