Ball Valves (PVC)

Ball Valves (PVC)

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...
Knife Gate Valves

Knife Gate Valves

Knife Valves allow you to tightly close off the water lines of the connected piping to allow for maintenance on joined mechanisms such as pumps or filters without shutting down your pond. Gate valves (also known as knife valves or slide valves) are linear motion valves in which a flat closure element slides into the flow stream to...
Swing Check Valves (PVC)

Swing Check Valves (PVC)

Swing Check Valves are mechanical valves that permit water to flow in only one direction, preventing process flow from reversing. They are classified as one-way directional valves. Fluid flow in the desired direction opens the valve, while backflow forces the valve closed. These install near your skimmer or filter, so if the pump is...
True Union Check Valves (PVC)

True Union Check Valves (PVC)

In general, True Union Swing Check 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 true union swing check valves offer rugged construction providing for a long service life, and a...
