The Runxin F71Q3 automatic backwash valve can be used on various FRP vessel sizes and filter media such as Silica sand, Activated carbon, Glass, Birm, Calcite, DMI-65 and others as long as the vessel has a 2.5” top opening.
The backwash valve allows you to flush out all the trapped dirt, rust or other particles trapped between the grains of media and will also rinse, re-set and re-compact the media bed to prevent and remedy channeling.The backwash valve uses a digital timer to automatically backwash and rinse every set number of days or hours and is easy to program and operate. Once it is set, the settings are saved for up to three days if power is lost.
The ports on the valve are all 3/4” (20mm) female threaded ports to connect to a variety of fittings and supports a maximum flow of 2,000L/h.
