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").

Range:

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
Seal: EPDM, FPM

Fields of Application:

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

Advantages:

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

Options:

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