Butterfly valve, type 567-568

Butterfly valves type 567/568 are compact, flexible and reliable shut-off valves for wafer and lugstyle applications. Our system's modular design principle allows you to exchange individual system components – fast, easily and at very little expense and effort. Type 567 butterfly valves are now available in dimensions up to


DN600/24" in PP-H and PVC-U (up to DN400/16").


Type 567: d63/DN50 - d315/DN600
New: Type 567 up to DN600/24"
Type 568: d63/DN50 - d225/DN200

Connections: Wafer or Lug-Style 
Standards: ISO, BS, ASTM und JIS

Nominal pressure:
up to DN300:
 Bidirectional PN 10 
DN350-400: Bidirectional PN 6
DN 450-600: Bidirectional PN 4

Materials: PVC-U, PVC-C, ABS, β-PP-H, PVDF


Fields of Application:

  • water treatment
  • power plants
  • shipbuilding
  • electroplating
  • chemical process industry
  • automotive industry
  • cooling equipment


  • 50% lower actuation torque compared to a centric butterfly valve due to the double eccentric operating principle
  • noticably reduced abrasion
  • integrated electric position indicator in the mounting flange
  • optimized gaskets
  • all components which are in contact with the media made of piping materials, consequently the permeation can be minimized
  • functional hand lever made of glass-fiber-reinforced polypropylene (PP-GF 30) with 5° ratchet setting, lockable


  • manual valves with hand lever or reduction gear
  • pneumatically or electrically actuated
