Hygenic Double Seal
Sequence Valves DU TYPE

  • ON-OFF Valve
  • BOTTOM UP
  • The double-seal structure which seal with disc seat of two independent stem parts prevents cross contamination in case that the disc seat is damaged.
  • By assembling as the valve manifold, the cross flow production is available, and it becomes possible to efficiently operate valves, save the number of valves, and save space.
  • There is various material of packing with the fragrance resistance of various detergents resistance for the wetted parts and it is suitable for the high-mix production.
