The 106-F-Type 5 non-modulating float valve is based on the 106-PG main valve. It is ideal for allowing normal forward flow to fill water tanks to a desired high level and where the pilot and valve of the storage tanks are easily accessible. The valve functions as a two-position valve, either open or closed. The valve remains closed when the tank level drops, until the float reaches the pre-determined adjustable minimum tank level. The F-Type-5 valve opens to refill the tank and closes tightly when high water level is achieved.
