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.
