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”

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).

14

Assembling cylinder & piston


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.
