Other names: Manual Whole house water filtration Valve MANUAL WATER FILTER VALVE RINSE/BACKWASH/FILTER SETTING F56A Manual Multi-port Filter Control Valve The USAQUAPRO F56A-1” Manual multi port Filter Control Valve features a flow rate of 17.6 GPM (4m³/h) and utilizes a ceramic sealing technology with corrosion resistant gasket for opening and closing functions. It can be used with tank sizes up to 1354, with heavy media like sand, and up to 1665 with GAC and/or Filter-AG. This valve is for use in water filters (carbon, sediment, multimedia, sand, or any other backwash media), for residential or commercial application. Media tank is usually a FRP tank, holding the media, and this valve will do backwash and rinse service for the media. Single tank control valve, no water pass when the valve is in washing. Has a Mounting base 2.5"-8NPSM, and Inlet/Outlet/Drain ports G1" Female threads or FIP1" threads with adapters if included. Control Valve has Service, Fast rinse, and Backwash modes, with manual operation. With a handle, you can switch the settings easily without turning off the pump or the power. When selecting a valve setting, make sure the handle arrow points to the desired mode directly (not in between two modes). NO electricity required. If you have started backwashing your filter, always make sure you backwashed enough time and intensity to get turbidity leave the tank. Usually it takes 6 -10 minutes to backwash. Use additional flow restriction valve or a washer on the drain line to limit drain flow for NOT to wash out the tank media. As the name suggests, the Manual filter Control Valve is operated by manually spinning the handle or hand wheel. Its handle can be turned 180 degrees and could be available in both plastic and metal. For tanks that range in size from 8" to 13", the installation technique is top-mounted. The primary applications for the Manual Filter Control Valve include carbon and sand filtration systems in homes, as well as swimming pool filtration, iron and manganese removal filtration, and pre-filtration systems for reverse osmosis treatment. It is possible to use F56A1 Control Valve to built an Iron removal filter utilizing an "Air Bubble" technology. In order to form an air bubble during filter regeneration, it is necessary to make minor improvements to the device's installation diagram and to the regeneration technology. The following changes to the installation diagram are required: 1. Install a tee between the inlet to the Valve and the shut-off valve on the intake line. 2. Connect a check valve to the tee branch, with the "outlet" (arrow) direction towards the tee, and with an air inlet protective mesh on the other side. That is, the second side of the check valve - the "inlet" - is connected to the ambient air and freely passes air into the tee. The mesh is needed to protect against insects. The change in the regeneration diagram includes an additional cycle of air injection into the tank, after fast rinse, it is necessary to close the inlet valve and leave for about 15 minutes. When the water stops flow into the drain, turn the Control Valve to Service mode and slowly open the intake valve.
