I. DESCRIPTION AND SCOPE
This manual covers the body assembly of the Cashco
Ranger QCT. Available sizes include 1", 1-1/2", 2",
3", 4", 6" and 8" (DN25, 40, 50, 80, 100, 150, 200).
Flangeless DI bodies fit 150 and 300 lb. RF flanges.
Flangeless CS and SST bodies, all sizes, fit 150,
300 and 600 lb. RF flanges. Integral flanged CS and
SST bodies, sizes 1" through 3", mate with 150, 300
and 600 lb. RF flanges. Integral flanged CS and SST
bodies, sizes 4", 6" and 8", mate with 150 and 300 lb.
RF Flanges. All sizes of flangeless construction may be
installed between PN40 flang 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 orifice
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
Ranger QCT body.
