Valves & Auto-Fills

FlowVis is a revolutionary, patented solution for accurate and reliable flow and velocity rate measurement in fresh water applications such as swimming pools, spas, fountains, water features, ponds, irrigation systems, ground water applications, well water and solar systems. As flow increases, the flapper moves forward toward its fully open position. The flapper’s angular position is directly related to the flow rate through the valve body/tee/pipe. A calibrated scale on the valve’s lid provides a highly accurate reading of the flow rate and velocity.

  • Ease of installation with zero to minimal straight pipe
  • Installation flexibility that allows orientation in any position, e.g., horizontal, vertical or even upside-down
  • Long life without sticking floats or paddle wheels
  • For use with external motor driven pumps only

Ball valves are an important component in pond plumbing systems, helping control water flow to filters, waterfalls, and other equipment. Their quarter-turn design allows pond owners to start, stop or regulate water flow. Because ball valves provide a tight seal and minimal restriction, they help maintain efficient water circulation, which is critical for keeping pond filtration systems working properly. They are commonly installed near pond pumps, skimmers, and biofilters to isolate equipment and fine-tune water flow throughout the pond system.

  • Available sizes from 3/4" - 3"
