Product Summary

Ball valves have a spherical closure element with a round or other-shaped hole in it. Aligning the hole with the flow opens the valve, and placing the solid outside of the ball in the flow shuts the valve. The ball rests on a valve seat, and the stem is inserted into the top of the ball. Packing and washers around the stem prevent leakage. A handle for manual actuation is attached to the stem. Stops keep the handle from rotating more than 90 degrees.

Ball valves have two or more ports. Connections to the ports offer the same options as for the gate valve. Ball valves made with three ports are used as mixing or diverting valves.

Flow Characteristics-----Ball valves can be designed so the flow is closely proportional to the rotation of the closure element. This is called a "modified equal percentage" flow characteristic. This makes ball valves suitable for active control of media flows.

Actuation-----Ball valves are actuated manually, and also by electric and pneumatic actuators as parts of flow control systems. One advantage of a manually actuated ball valve over a gate valve is the handle position makes the position of the ball easy to "see."
