High Performance Butterfly Valve

| • Integrally cast mounting pad
provides direct mounting of Keystone 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. • Uninterrupted flange face retaining ring allows use of standard spiral. wound gaskets and provides uni-directional dead-end service as standard. Bi-directional dead-end service available. • 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.
