Features

Integrally cast mounting pad provides direct mounting of many actuators.
Rocker-shaped gland bridge compensates for uneven adjustment of gland nuts.
Extended neck allows for two inches of pipeline insulation.
Flattened body bore at shaft journal ports positions shaft bearings near disc, providing maximum shaft support.
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.
Integrally cast disc position stop perfectly locates the disc in seat, achieving maximum seat and seal life.
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.
