350 series
filter backwash hydraulic valves
for water filtration systems the 350 series of valves are characterized by simple design that guarantees smooth operation and extended, trouble-free service.
each valve's diaphragm-actuated plug assembly keeps the water supply port closed when opening the backwash port (and vice-versa). the inherent short travel of the plug assembly results in smooth change of flow direction and water conservation. the valve also features a dynamic seal for drip-tight closure of the supply and drain ports.
