Pond Plumbing » Ball Valves

Ball valves are quarter-turn, straight through flow valves that have a round closure element with matching rounded seats that permit uniform sealing stress. 

Ball valves are used in situations where tight shut-off is required.  The type of seat can vary with the valve pressure rating and materials of construction.  

This may be used as a disconnect to allow access to your pump, filter, or reservoir to allow for easy maintenance.

In general, ball valves offer many advantages when contrasted with other valve types. They provide superior ease of operation and can maintain and regulate high volume, high pressure and high temperature flow. 

Most ball valves offer rugged construction providing for a long service life, and a comparably low cost. 

Additionally, the design of the regulating element allows the valve to function without the complications of side loads, typical of butterfly or globe valves, and the valve design permits inspection and repair of seats and seals without removing the valves’ body from the line.
