A multiport valve changes the operating mode of a compatible swimming pool filtration system.
Multiport valves are commonly installed on sand-filter systems and allow the operator to select functions such as filtration, backwashing, rinsing, waste, recirculation, and closed mode. The valve must be compatible with the filter, plumbing connections, and required flow rate.
