    KEYSTONE FIGURE 129/239 BUTTERFLY VALVE

    ₮0.00

    • Replaceable, metal-reinforced seat, completely encapsulated by rubber, isolates

    the stem and body from the media and eliminates seat distortion due to high vac-
    uum or turbulence.

    • Primary stem seal, formed by preloaded contact of disc hub with flatted seat sur- faces, completely isolates stem and body from the line media.

    • Secondary stem seal, formed by an engineered interference fit of the stem through the seat, provides additional sealing integrity.
    • Rounded, polished disc edge provides full 360 degree concentric seating, minimum flow restriction, lower seating and unseating torques and maximum seat life.
