Guide to Bonnet Selection Selection of the bonnet design is undertaken on the basis of both the operating temperature range and fluid media being handled. Figures 2 to 5 illustrate the bonnet design options available for use with the Introl Series 10 range. Table 2 below provides a general guide to the temperature limitations of various bonnet designs and packing materials available. Where fluid working temperatures below -20°C (4°F) and above 400°C (752°F) are specified, normalising bonnets are recommended to protect the valve packing against extremes of temperature.

The Bellows Seal Bonnet option, as illustrated in Fig 5., ensures absolute sealing of the process fluid within their rated pressure and temperature ranges. An auxiliary packing box in the upper bonnet serves as an emergency seal in the unlikely event of bellows failure Table 1. Bellows Seals Working Conditions

Velocity Limitations In selecting a valve for either a liquid or gas/vapour application one of the major considerations is the effect of fluid velocity. High velocity could lead to operational problems including erosion, excessive vibration and instability. The following tables indicate the maximum recommended velocity values for liquid and gas/vapour services. Table 6.

Engineering Data - Introl Series 12 Range General:

Modular Design:

The Introl range of globe control valves has been developed by ABB Control Valves Ltd. to provide a cost effective solution to the ‘final control element’ used in modern plants. The valve design combines the successful high integrity features of the Introl Series 10 range with a high capacity, economic design philosophy. The Introl series of control valves are ideally suited to meet the various process control requirements demanded from a wide range of related industries

The Introl range has been designed around a modular manufacturing concept. Using this philosophy, a centre body module selected to most suit the specified flow conditions and operating data, is combined with an end connection size/rating, selected to support that module. This design feature allows not only the selection of full size ends, but gives the facility, where conditions permit, to offer oversize end connections to suit a particular requirement.

General Selection Information The information detailed is intended to act as a general guide, to assist in the selection of an Introl Series 12 control valve. Trim Cv Calculation A full description of the procedures used for calculating the Cv on various fluids is detailed in the Introl Sizing and Selection Manual Body Selection Generally, the valve body must be capable of supporting the selected trim design without producing excessive velocity The following tables can be used as a guide for determining the maximum recommended body velocities for liquid and gas/vapour applications. Liquid Service The velocity guidelines detailed in Table 3 below, reflect the normal inlet and outlet maximum velocities recommended to eliminate body erosion and prevent trim instability. Other factors may reduce the following figures further. Refer to Introl sizing and selection manual. Table 3. Recommended maximum inlet and outlet velocities liquid service.

Definitions:

• •

Linear Flow is directly proportional to valve lift.

•

Quick Opening Flow increases rapidly with initial travel reaching near its maximum at a low lift.

Equal % Flow changes by a constant percentage of its instantaneous value for each unit of valve lift.

Maximum Leakage Rates Leakage rates are normally measured in accordance with the ANSI/FCI70-2-1976 specification using the class designation. The following Table 6 defines the achievable leakage class for each available plug design. Table 6. Achievable Leakage Class

Guide to Bonnet Selection Selection of the bonnet design is undertaken on the basis of both the operating temperature range and fluid media being handled. Figures 2 to 4 illustrate the bonnet design options available for use with the Series 20 range. Table 1 below provides a general guide to the temperature limitations of various bonnet designs and packing materials available. Where fluid working temperatures below 0°C (32°F) and above 250°C (482°F) are specified, normalising bonnets are recommended to protect the valve packing against extremes of temperature. The Bellows Seal Bonnet option ensures absolute sealing of the process fluid within their rated pressure and temperature ranges. An auxiliary packing box in the upper bonnet serves as an emergency seal in the unlikely event of bellows failure. Fabricated extension bonnets in stainless steel are available as a special option when a longer extension is required on cryogenic service.

Three Way Globe Valve Introl “Series 30” - Inside Seating Introl “Series 31” - Outside Seating Introl “Series 32” - Balanced For ratings ANSI 150-600 (PN 10 - PN 100)

Introl Series 30 - Features General The Series 30 valve is a three-way design of valve for use on blending two separate flows, by having two inlets and a common outlet port, or dividing a flow into two proportional parts by having one common inlet and two outlet ports. This range of valves has been designed in three forms designated 30, 31 and 32, the first incorporating an inside seating trim (Fig. 1 ) to provide an economic solution for all mixing and selected diverting services. Series 31 incorporates an outside seating trim (Fig. 2) which is specifically designed for high duty diverting service applications, while the Series 32 uses a balanced plug for diverting service. Size for size the Design Cv of the trims is the same regardless of the selected seating arrangement. An additional Series 32 valve is also available with balanced trim for high differential pressure shut-off. Performance:

• •

High flow capacity.

•

High rangeability - well in excess of usual control system requirements.

Figure 1. Introl Series 30 - Inside Seating

Leakage capability - better than ANSI Class IV and consistent with normal single seat valve specifications.

Design Flexibility:

•

The availability of either an inner or an outer seated design to minimise any flow instabilities.

•

Standard or normalising bonnets options to suit temperature conditions.

• • •

Bellows seal available for positive leak proof stem seal. Wide range of interchangeable trim sizes. Full range of body and trim materials available.

High Duty Parts:

•

Heavy duty top guide with additional skirt guiding on the plug - effective in both seats.

•

Seats are generously proportioned and are screwed into body to ensure a leakproof seal.

•

Case globe type body one piece construction with bottom connection bolted to main body. The bottom connection is in the same material and has the same pressure rating as the main valve body.

•

Deep all purpose packing box accommodating a variety of proprietary packings.

ABB Control Valves

Figure 2. Introl Series 31 - Outside Seating

Quality Manufacturing:

• •

Rigorously tested to ensure specified performance on site.

•

Optional full NACE MR-01-75 certification.

Quality Assurance systems in accordance with BS5750 Part 1 1987/ IS0 9001 1987/ EN29001/1987.

Flow Coefficient (Cv)

All Cv values given in the following table are stated in U.S. units. The values given are with one port closed. Full procedure for calculating Cv values is detailed in Introl Sizing and Selection Manual. Inherent Rangeability: The inherent rangeability of a valve trim is dependent on a number of factors including size and style. The values detailed in Table 1 below provide a general guideline to the maximum achievable values. Table 1.

Guide to Valve Selection •

Bonnets Where fluid working temperatures of above 250°C or below 0°C are specified, normalising bonnets are recommended to protect the packing against extremes of temperature. In both cases the standard form of connection is the bolted bonnet arrangement.

•

W Bellows Seal Bonnet Bellows seal valves ensure absolute sealing within their rated pressure and temperature ranges. An auxiliary packing box in the upper bonnet serves as an emergency seal in the unlikely event of bellows failure.

•

Diverting Duties The Introl Series 30 valve fitted with the Introl Actuator may be used for selected diverting duty as shown in Table 7.
