Flangeless CS and SST bodies, all sizes, fi t 150, 300
and 600 lb. RF fl anges. Integral fl anged CS and SST
bodies, sizes 1" through 3", mate with 150, 300 and

Flanges. All sizes of fl angeless construction may be
installed between PN40 fl ang es. Quick Change Trim
(QCT) is furnished as a stan dard feature and allows
use of several seal re tain ers and inserts to vary orifi ce
size, help control cav i ta tion and reduce noise. All trims
use 90° plug rotation. Dis as sem bly, in spec tion and
reassembly of the trim can be accomplished easily
without disturbing the packing, linkage or po si tion er
calibration. Trim parts are self-centering.
Either of Cashco's pneumatically actuated actuators,
Model 48 and Model 148, can be mounted to the
