Type 567 line includes
14 to 16" valves with a double-eccentric off-center design and good chemical
compatibility. The off-center shaft allows the disc to completely disengage
from the disc seal, even when partially open, which reduces seal friction. The large
size valves have industry-standard ISO flange mounts to ease electric or
pneumatic actuation. They have either EPDM or FPM seals, 304 or 316 stainless
steel stem, and a polypropylene body.
