 Standard Hard Trim Materials–Thecage,valveplug,
and other trim parts are manufactured from
hardened materials. This standard feature provides
excellent wear resistance.
 Control of Low Flow Rates/T ight
Shutoff–Micro-Flute and Micro-Form valve plugs
(figures 6 and 7, respectively) p rovide superb
rangeability in high-pressure, low-flow applications,
while maintaining tight shutoff (table 4). A choice of
several restricted port diameters helps to match
valve body capacity to required flow, to provide
necessary control with fulltravel,andtoprevent
throttling near the seat.
In low-flow applications where cavitation damage
may occur, the Micro-Flat valve plug can be used
with a special Cavitrol III cage. Contact your
Emerson Process Management sales office for more
information.
 Increased Pressure/Temperature Ratings– HP Series
valves with weld-end fittings have increased
pressure/temperature ratings, called intermediate
ratings, as defined in ASME B16.34. The extra
strength of these valves allows ratings higher than
the standard CL900 or 1500 ratings specified in
B16.34. Contact your Emerson Process
Management sales office for further information on
intermediate ratings.
 Trim Interchangeability–Cavitrol III, Whisper Trim
III, and WhisperFlo trims (figures 8, 9, and 10) are
interchangeable with standard trims.
 Smooth Control at High Pressure Drops–Available
on NPS 2 through 6 valves, balanced trim provides
smooth control at high pressure drops.
 High-Temperature Capab ility with Class V
Shutoff–Use of C-seal trim (see figure 5) permits
Class V shutoff up to 593_C (1100_F) for HPD
valves.
 Sour Service Trims Available–Long-lasting, erosion-
and corrosion-resistant trims are available for
control of sour service. These trims are offered with
either a standard cage, a Cavitrol III cage, a Whisper
Trim III cage, or WhisperFlo trim. Spiral-wound
gasket construction is standard.
