Flat Automatic Multiport Valve

The Flat Automatic valve combines the flat body of the Flat series with a motorised actuator and an electronic control board. A pressure switch monitors the pressure that rises as the filter clogs; when the set limit is exceeded, the valve moves to backwash, then performs a fixed 30-second rinse and returns to filtration.

The backwash duration is adjusted to the site's needs with a potentiometer on the electronic board. The automatic system is rated IP65; the valve runs on a 230-115 Vac / 50-60 Hz supply and draws a maximum of 14 W. It is designed for a service life of 5,000 backwash and rinse programmes and can be used up to 2,000 m above sea level.

Nominal flow is 12 m³/h and the maximum head loss is 0.66 bar. The body is ABS, the distributor PPO and the gaskets EPDM; pump, return and waste connections are 1½" BSP threads. The side-mount model (43513) has a Ø50 mm solvent-weld filter outlet; the top-mount model (43512) fits directly onto top-mount filters.
