Features (continued)
 Quick and Easy Maintenance–All trim parts are
retained without the use of press fits or screw
threads exposed to the process fluid. See figure 1.
 Structural Integrity–The valve body, complete with
flanges, is made from a one-piece casting. No
welding is employed. No O-ring seals are used. Use
of a flanged valve body does not require the use of
extra long studs.
The shaft seal is made from well-proven PTFE
chevron ring packing with the means for external
adjustment.
Options
 A PSZ (partially stabilized zirconia) ceramic flow ring
insert is available with HCI (high chrome iron) or PSZ
ceramic ball for particularly aggressive slurry
services with extended lifetime requirements. The
ceramic i nsert offers substantial increase in flow
ring lifetimes.
 Trim materials are available to meet the
requirements of corrosive/erosive slurries.
See table 2.
 The“FlowOvertheTop”V-NotchBalloffersan
alternative to the standard V-Notch Ball in scaling
applications.
 The drive shaft is available with either a double D or
splined actuator connection to accommodate a
choice of actuation between a spring-opposed
diaphragm or a rack and pinion.
