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.
