CMI Globe Valves
This catalogue describes our line of globe valves only. Other
Bonetti’s “CMI” products, such as gate and globe valves, are
described in other bulletins available on request.
DESIGN
All valves described herein are either:
- straight-through, with a vertical stem (T pattern), or
- angle type, or
- Y pattern with an inclined stem.
This last body pattern allows a streamlined smooth flow, less
turbulence and as consequence less internal erosion, less
pressure losses, etc.
OPERATIONS
Bonetti’s “CMI” valves described in this catalogue perform the
following functions:
- Stop on-off shut off to fluid flow;
- Stop and throttle - when a parabolic shaped disk is used in
lieu of a standard stop disk. A linear flow control
characteristic is achieved as a direct function of the stem
turns;
- Stop check - both a stop and a non-return valve;
- Piston lift check - for automatic prevention of undesired
reverse flow.
CONNECTIONS
Bonetti’s “CMI” valves illustrated in this catalogue have the
following pipe connections:
- Flanged ends according to ASME B16.5 (usually for Class
600 only, not for higher pressure Classes) or to different
Standards;
- Butt weld ends in accordance to ASME B16.25. (See pages
30 and 31 for different standards.).
We can supply valves with connections as needed.
SIZES
Bonetti’s “CMI” valves are currently manufactured in sizes from
2" (DN 50) up to 24" (DN 600).
RATINGS
Bonetti’s “CMI” valves are currently manufactured as per the
following Ratings:
ASME Class 600, 900, 1500 and 2500;
(PN 100, 150, 250 and 420).
As indicated in the foreword, Bonetti’s experience is not limited
to the above pressure classes. Tables showing max operating
conditions (pressure and temperature) for pressure ratings and
material codes are given on pgs. 28 – 29. We wish to point out
that Bonetti’s “CMI” valves are over dimension with respect to
most international standards. Actual max. operating conditions
can be supplied on request.
The Material Codes with tag followed by a -” Z “ are special
constructions, slightly different from the standard one.
STANDARDS
Bonetti’s “CMI” valves have been designed, rated, manufactured
and inspected, where applicable, in accordance with most widely
used international Standards, namely:
- ASME B16.34 "Steel valves, Flanged and Butt welding Ends"
- ASME B16.10 "Face-to-Face and End-to-End Dimensions"
- Applicable Sections of ASME Boiler and Pressure Vessel
Code, including Nuclear Section III
- MSS SP 44 "Steel pipe line flanges”
- MSS SP 61 "Hydrostatic testing of steel valves”
- API Standard 598 "Valve inspection and test”
- ASME B16.25 "Butt welding ends"

MATERIAL CODE
Bonetti’s “CMI” valves are manufactured in different material
codes. For "Material code" we mean the material composition of
the valve parts.
The descriptive pages relevant to each valve clearly indicate the
materials used for the more important components and the
corresponding “Material code”.
Below we list the main characteristic elements of the different
Material Codes:

1 BODY
Available of Carbon steel and various alloy steels, is usually
of cast material. For some sizes and classes can be of forged
material.
Machining is properly performed, for perfect aligment of all
elements. In its inner two fine machined grooves guide the
relevant tongues of the wedge or disk.
The seat rings are welded-in after complete finish. When the
bonnet is pressure seal (Fig. 102), a stainless steel inlay (26)
on the body-gasket sealing area guarantees effective and
long-life bonnet closure.
3 SEAT RINGS
Both seat rings are stellite hardfaced, completely machined
and then welded into the body. Their shape does not allow
distorsions of sealing surfaces by pressure and temperature
changes.
Bore dimension of the seat rings is according to ANSI B16.34
- 1981 Table G-A1 and tolerances given on Paragraph 6.1.2.
2 BONNET
Usually of the same material as body. It can be:
- bolted to the body, or
- pressure seal, or
- seal welded to the body.
Pressure sea! bonnet is pushed from inner pressure
against pressure seal gasket (10) which is kept in place by
the spacer ring (25) and the segmental ring (12), see Fig.
102, or directly by the yoke. Specially accurate are:
- easy beginning of pressure seal
- easy disassembling and reassembling.
Stem backseat area is hardfaced, usually Stellited.
4 WEDGE
Usually two-pieces split wedge, for perfect sealability to the
seat rings. The wedge tongues are trapped and fully guided
by the body grooves which are long enough for the whole
stroke. The wedge is directly moved by the stem head
trapped between wedge halves.
This way: the stem is non-revolving; the point at which the
force acts is as down as possible; the height and the weight
of the valve are minimized.
Wedge seats are stellite hardfaced. Wedge tongues are
hardfaced, usually stellited (27).
In the gate wedges, the spacer (5) trasmits the closing force
through the wedge halves against the seat rings. To facilitate
field repairability, the spacer can be replaced with a thicker
one, without replacing the whole wedge. In the parallel slide
valves, the disk spring (5.1) keeps both disk halves against
the seat rings, to begin closure seal.
6 STEM
Of 13% Chrome stainless steel, heat treated against corrosion
and for the best mechanical features. Above the head
trapped between the two wedge halves (Fig. 104) the stem
has a conical shoulder which - when the valve is fully open -
is pulled against bonnet for effective backseating with axial
(not rotating) movement.
In the parallel slide valves, the stem can not rotate because
of indexing stop (21) which acts two more functions: the
positive end of the stroke; the index of actual disk position.
The yoke nut is rotated by the hand wheel through a key, orthrough the actuator stem nut adapter. The rotation of the yoke nut is guaranteed by two roller bearings. When necessary, tapered cone bearings are used.
9 PACKINGComposed of the appropriate number of preformed rings asrequired for the pressure and temperature conditions. Standardmaterial of construction is graphite. Other materials are available upon request.The entire packing assembly consisting of packing chamber,packing, gland, gland stud (15 – 15.1), and packing follower (16), are carefully manufactured and assembled to insure long packing life with leak free performance.

23 HANDWHEELImpactor type hand wheels are standard supply. Other kinds of operators are and, in some cases, are indispensable for the valve’s operation. These include:- chain wheel;- gear operator, and if required, universal joint and stand;- gear operator with impactor hand wheel;- electric, or electric hydraulic actuator;- pneumatic actuator.When requested, actuators are factory mounted and tested to insure safe reliable operation. Because there are so many actuator options, and customer’s requirements, this catalog only describes valves without actuators even though actuators are often required. Our technical department will be glad to supply necessary data to insure proper selection and actuator supply.
29 EQUALIZER PIPEWhen required, an external pipe is welded to the body of piston and stop check valves (fig. 204). This pipe connects the relatively high pressure area above the disk with the valve’s outlet side which is under a lower pressure. So doing, the pressure above the disk is reduced allowing the disk to open quickly and to the full open position, even when there is low flow rates. So doing also minimizes pressure drop losses and disk vibration.
For any components shown on these pages but not itemized or fully described in the various Figures, please refer to the details shown at the bottom of each descriptive product page.
Notes for materials(Those notes apply also to rating tables on pag. 30)
Chemical analysis and mechanical features are given for Customer’s convenience only. Actual and binding values are the ones prescribed by original Standard
1 We also utilise steel with lower Carbon content (<0,25%).2 Mechanical features depend on heat treatment. Prescribed heat treatment permits us to obtain the most suitable physical and chemical characteristics.3 Ratings of tables on page 30 are those indicated by ASME B 16.34 for Classes 600, 900, 1500, 2500, 4500 and extrapolated for Classes 1700 - 2700.
4 Due to a possible transformation of carbide into graphite, ASME B 16.34 does not recommend the use of Carbon steel valves (BONETTI material code “CB”) over 800 °F (425 °C) for extended periods.5 For A217 WC6 and A217 WC9 valves (BONETTI material code “C6” and “C9”), ASME B 16.34 recommends: “Use normalised and tempered material only - Not to be used over 1100 °F (595 °C)”.6 At temperatures above 1000 °F (538 °C), material A351 CF8M (BONETTI material Code CF8M), must be used only when the Carbon content is 0.04% or higher.7 As BONETTI’s “CMI” valves are oversized versus International Standard prescription, including ASME B16.34, effective maximum operating condition can be communicated on request.

AV2 valve AV3 valve
Quick acting automatic 2 and 3 way valvesfor H.P. Pre-heaters bypass systems.
Valves are hydraulic self-actuated by means of an integral piston whose speed is controlled byan external regulating valve.Meeting ASME Class 900 thru 2500, and special classes. Available in sizes up to 18”
OPERATION
These fully automatic valves are operated by a piston which is
integral to the stem. The piston slides within a cylinder which
is itself integral to the pressure seal bonnet.
The stem-piston-disk assembly derives its motive force from
the pressure of the fluid being handled, without the need of an
external power source. The piston is sealed within the
cylinder by means of piston rings.
In the 2-way valves, AV-2, the disk opens or closes the
passage of fluid between the inlet and outlet ports.
In the 3-way valves, AV-3, the disk intercepts the passage of
the main fluid flow and diverts this flow to a secondary by-
pass, or an emergency line.
The stem-piston-disk assembly is connected to the threaded
stem, or hand wheel, by means of a yoke. It may also be
operated manually and locked in place.
The valve’s operating speed (and the length of its cycle) may be
controlled by means of separate auxiliary control valve (CV1 and
CV2 in figure at page 17).
These automatic by-pass valves are typically installed on the
condensate or feedwater lines of thermal power stations. They are
designed to automatically intercept fluid flow to the HP feed water
preheater, in case of a
high water level condition in the preheater shell. This design
includes:
- One 3-way automatic valve, AV-3, whose function is to switch
over the water flow from the preheater to the by-pass line.
- One 2-way automatic valve, AV-2, designed to function as a
stop-check valve, isolating the preheater’s outlet from the feed
water line.
- One set of auxiliary control valves (CV1, CV2, MGV and RV1 in
figure at page 17).

Assembling cylinder & piston
Quality Valves & Level Gauges
After the activation of the automatic valves, AV2 and AV3, the flow
of water to the boiler is established through the by-pass piping
system. The operation in the by-pass mode may be maintained
indefinitely by manually operating the stem-piston-disk assembly
by means of the hand wheel which can be locked in place.
CONNECTIONS
Typical connections are butt weld ends (BW), as per ASME
B16.25. Other connections are available on request.
