The Keystone K-LOK 360/362 and the Keystone K-LOK 370/372 are high performance Butterfly Valves. The K-LOK 360/362 and K-LOK 370/372 are suited for use in high performance applications such as steam, chilled water, gasoline, natural gas, air, oil, jet fuels and hydrocarbon process lines.
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 stem journal ports positions stem bearings near disc, providing maximum stem support
Disc taper pins are tangentially positioned half in disc and half in stem, 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.
