Features and benefits
•t Integrally cast mounting pad provides
direct mounting of many actuators.
•t Rocker-shaped gland bridge compensates
for uneven adjustment of gland nuts.
•t Extended neck allows for two inches of
pipeline insulation.
•t Flattened body bore at shaft journal
ports positions shaft bearings near disc,
providing maximum shaft support.
•t Disc taper pins are tangentially positioned
half in disc and half in shaft, placing them
in compression rather than shear, which
eliminates potential for failure.
•t Integrally cast disc position stop perfectly
locates the disc in seat, achieving
maximum seat and seal life.
•t K-LOK polymer, elastomer, and fire-safe
seats provide bi-directional, drop-tight
closure in vacuum and throughout all
pressure ranges, as well as at full rated
differential pressure. A variety of materials
allows optimum seat life in all applications.
