Multiport Valves in Swimming Pools Use Reed Switches

Swimming pool filtration systems rely on multiport valves to manage various water treatment cycles, including filtration, backwash, rinse, and drain. In a manual system, a service person must turn the multiport valve to the appropriate position for each cycle and monitor the duration manually. This process ensures proper cleaning and maintenance of the pool water, but it requires constant oversight and precise timing to avoid inefficiencies, such as over-filtering or incomplete backwashing, which can affect water quality.

Automatic multiport valves help this process by eliminating the need for manual intervention. These valves are designed to transition between cycles automatically, based on pre-set programming. To achieve this level of automation, reed switches are incorporated into the valve system. Reed switches detect the exact position of the valve during its rotation, ensuring that it stops at the correct position for each cycle. This automation reduces the need for a service person, improves operational efficiency, and ensures that each cycle is performed accurately and consistently.

The mechanism of an automatic multiport valve works by utilizing an embedded magnet that moves with the valve’s turning mechanism. Inside the valve, reed switches are strategically positioned to correspond to each operational cycle: filtration, backwash, rinse, and drain. As the valve rotates, the embedded magnet aligns with a reed switch, closing its circuit and signaling the control system to stop the valve. This ensures that the valve halts precisely at the required position for each cycle to maintain high efficiency of flow.. The system then activates the corresponding operation, such as initiating backwash or resuming filtration.

By integrating reed switches into automatic multiport valves, swimming pool filtration systems become more efficient and user-friendly. This technology ensures precise cycle control, reduces maintenance demands, and maintains consistently clean and safe pool water.
