Hi-Lo Combi Valve (BALEM 531-S) is progressed in performance of BALEM 421 and 531,      
has great flux quality using efficient internal design, and can control high and low water level.      
      
All materials are stainless steel, so the valve can be used not only   controlling high and low level      
but also controlling in drinking water  and  demineralizing water      
      
      
      
▶ Features      

   •  Hydraulic level control valves by differential pressure and buoyancy of float.      
           
   •  Stainless steel main valve-suitable for demineralizing water control.      
             
   •  Operates mechanically independent from any external power sources.      
      
   •  Easy to install without additional pipes.      
            
   •  More safe in high pressure and stronger in water hammer by differential pressure

       being applied to piston operating system.
