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.
