    Features

    ? Factory testing of every valve at full rating
    ensures 100% bubble-tight shut-off.
    ? Standardized actuator flange for easy
    operator interchangeability and mount
    direct to Keystone Range of actuators.
    ? One-piece wafer-thin disc-stem provides
    high strength and absolutely positive disc
    control and gives the very minimum
    obstruction to flow. Its crevice free surface
    makes it ideal for hygienic duty.
    ? Primary seal formed by the seat/shaft/hub
    contact exceeds the pressure rating of the
    valve. Body is totally isolated from the
    flowing medium.
    ? Secondary shaft seal is suitable for
    pressure and vacuum is self adjusting.
    ? Patented dove-tail seat requires no
    bonding. Makes seat replacement simple
    and fast. Extra heavy edge section resists
    tearing.
    ? Hub seal is provided by preloaded contact
    between flatted seat surface and rounded
    polished disc-hub area for positive sealing
    at all disc positions.
    ? Molded-in O-ring provides positive flange
    sealing and eliminates the need for
    gaskets.
    ? Heavy duty top bushing absorbs side
    thrust loads. Self-adjusting sealing for both

    directions is also suitable for vacuum.
