 Freycinet valve (Flowxvalve) - Production of electrical moving ball valves, butterfly valves Freycinet, Italian quality brand valve: FLOWX a total overview of automatic backwash filter system dedicated hydraulic control valves, pressure driven by the pipeline system, can be automatically 2-way switch, to achieve automatic filter backwash, simple structure, high reliability, ensuring stable operation for a long time without maintenance situation. Membrane structure just a short drive stroke to smoothly change the flow of water in the backwash mouth open and close the intake and vice versa. Avoid filter water and waste water overflowing or mixed. Simple structure, easy to install, saving investment superior hydraulic performance, the digital conversion frictionless high reliability, moving parts smooth operation, accurate positioning anti-chemical corrosion materials, suitable for a variety of media flow turned quickly, high efficiency discharge rinse. Typical applications backwash valve applied to at least two parallel filtration unit automatic backwash filter systems, namely: In the backwash process, filtered through a filter unit to clean water as another wash water filtration unit. When the received signal issued by the controller hydraulic backwash valve to divert the flow of water: Turn off the water inlet, open drain, the other filter unit filtered clean water entering the unit to wash and rinse water through the discharge port emissions.
