DIAPHRAGM VALVES

O. PURPOSE

1

The purpose of this Standard Practice is to outline the limitations and requirements ofvalves in which a nonmetallic, resilient diaphragm is used to separate the working parts of the valve from the line fluid and also functions in conjunction with other parts as valve closure-member.

The use of a nonmetallic, resilient diaphragm causes the valves described in this Standard Practice to be different from other commonly used valves for which general and specific Standards and Standard Prac- tices are in existence. These differences include pressure-temperature limitations, face-to-face dimension requirements, and specific service characteristics.

This Standard Practice reflects industry practice in the design, manufacture, and application of this type of valve.

SCOPE

1.1 This Standard Practice applies to valves for general liquid and gas service that effect valve closure by means of a resilient diaphragm sealing against a weir or a diaphragm acting in conjunction with a separate or integral disk-member sealing against a seat, having equal sealing capability in either flow direction, and having diaphragms being essentially made of elastomeric or plastic material or combinations thereof.

1.2 This Standard Practice defines the following categories of valves:

The purchaser, when referencing the Standard, shall also specifj the appropriate category as listed above.

2.

This Standard Practice covers the following:

Pressure-Temperature Ratings and Design requirements Commonly Used Diaphragm Pressure Limitations Body, Bonnet, and Bolting Materials Commonly Used Face-to-Face Dimensions for Flanged Valves Body End Connections and Wall Thick- nesses Actuator Application Requirements Tests Marking

PRESSURE-TEMPERATURE RATINGS

2.1 Category A Valves: (Class 125 or 150) The maximum nonshock pressure-temperature ratings of valve bodies for valves in this category shall be those specified in the applicable Standards referenced in Table A3, Annex A, and the valve bodies must conform to the applicable requirements of the referenced Standards (see Subsections 2.4 and 2.5 for service ratings of the diaphragms).

2.2 Category B Valves: (Standard Valves) The maximum nonshock pressure-temperature ratings of valves in this category shall be those listed in Table Al, Annex A. Body wall thicknesses shall be those established by the applicable requirements of the referenced Standards in Table A3, Annex A.

a) b) c)

Class 125 or 150 Valves (See Subsection 2.1) Standard Valves (See Subsection 2.2) Valves for Special (Low Pressure) Applications (See Subsection 2.3)

1



2.3 Category C Valves: (Special Valves, Low Pressure) The maximum nonshock pressure-temperature ratings of valves in this category shall be those established by the manufacturer for the particular design.

2.4 The actual service pressure-temperature rating of the assembled diaphragm valves shall be limited to the pressure-temperature rating of the body or the diaphragm, whichever is lower, as outlined in Sub- section 2.5.

2.5 The service ratings of the diaphragms shall be those established by the valve manufacturer for the design and material selection for the intended service. Maximum allowable temperatures for elastomeric, plastic, or combined elastomeric and plastic diaphragms vary with the manufacturer’s design and the material composition, therefore, standard values cannot readily be established.

In order to enable the manufacturer to make proper recommendations regarding diaphragm and valve type and material selection, the following conditions shall be provided by the user:

valve size pressure temperature medium handled, including concentrations of acids or bases mode andor frequency of operation flow rate line shock conditions vacuum use of line cleaning fluids submersion of valve.

3. DIAPHRAGMS

3.1 Diaphragm materials shall be as recommended by the valve manufacturer for the intended service, considering the limitations, as outlined in Subsection 2.5.

3.2 Diaphragms are dimensionally not interchange- able between the various diaphragm valve designs made by different manufacturers. Replacement diaphragms must be purchased for a specific model of a valve manufacturer to assure the proper dimensional fit.

3.3 Diaphragms determine the service rating of diaphragm valves in most cases, as outlined in Subsec- tions 2.4 and 2.5. Therefore, if a replacement diaphragm is being used that does not show the valve manufacturer’s name, initials, or easily identifiable trademark, the valve service-ratings established by the valve manufacturer are invalid.

4. BODY-BONNET JOINTS

4.1 Body-bonnet joint bolting shall be designed to meet the allowable bolting stress specified in ASME Boiler and Pressure Vessel Code, Section VIII, Divi- sion 1 , at 100°F (38°C) for the bolting material being used.

4.2 Carbon steel bolts or studs shall meet the minimum mechanical and the chemical property requirements of ASTM A 307, Grade A or B.

4.3 Stainless steel bolts or studs, when specified by the customer, shall meet the minimum mechanical and the chemical property requirements ofASTM A 193, Grade B 8.

4.4 Alloy steel bolts or studs, when specified by the customer or when required in Category A valves, shall meet the minimum mechanical and the chemical properties requirements of ASTM A 193, Grade B7.

4.5 Other corrosion resistant body-bonnet bolt or stud materials or other body-bonnet fastening methods are not covered by this Standard Practice.

2



5 . BODY MATERIALS

Body materials shall conform to the Standards referenced in Table A4, Annex A. Non listed materials such as special alloys and plastics are not covered by this Standard and are subject to agreement between customer and manufacturer.

6. BONNETS

6.1 The bonnets of manually operated valves shall be capable of withstanding the hand wheel dosure forces and full-pressure loading in the event of a diaphragm failure.

6.2 The bonnets of valves with actuators must be, in addition to the requirements of Subsection 6.1, capable of withstanding mechanical stresses induced by the weight of actuators or any other auxiliary equipment in all possible valve installation positions.

6.3 Except as provided in Subsection 6.4, bonnet material shall be cast iron, malleable iron, ductile iron, or cast steel at the manufacturer’s option, regardless of body materials, unless one of these bonnet materials is specified by the customer or a different bonnet material is agreed upon between customer and manufacturer.

6.4 When the customer specifies apressure- retain- ing bonnet for Category A valves with body pressure-temperature ratings for Class 125 or 150, the bonnet shall conform to the wall section and material requirements of the Standards listed in Table A3, Annex A.

6.5 The seal of the sealed bonnets, when specified by the customer, shall be designed to contain line pressure or vacuum in the event of diaphragm failure.

7. BODY FACE-TO-FACE DIMENSIONS

Face-to-face dimensions of flanged diaphragm valves and valve centerline-to-top dimensions are peculiar to the particular manufacturer’s design. Consult each manufacturer for specific dimensions. Commonly used face-to-face dimensions of flanged diaphragm valves are given in Table A2, Annex A, for the guidance of diaphragm valve users.

8. BODY END CONNECTIONS AND WALL THICKNESS

8.1 Body end connections shall conform to the Stan- dards referenced iA Table A3, Annex A.

8.2 Body wallthicknesses of Category A and B valves, shall conform to the Standards referenced in Table A3, Annex A, for Classes 125 and 150.

8.3 Body wall thicknesses of Category C valves specifically designed and marked for pressure ratings lower than those specified in Subsection 2.1 and 2.2 shall be the manufacturer’s standard.

9. ACTUATOR APPLICATION REQUIREMENTS

9.1 Manually operated valves shall be actuated by handwheels or quick-opening levers with counter-clock- wise rotation to open the valve. Different means of manual actuation can be specified after agreement between customer and manufacturer.

9.2 Handwheels shall be of sufficient diameter to en- sure tight, manual closure at the specified service pressure of the valve.

9.3 Handwheels shall be marked with the direction of movement for opening the valve.

3


9.4 Pneumatic, hydraulic, pneumatic spring return, hydraulic spring return, or electric actuators shall be sized to be capable of closing the valve against a minimum of 1.1 times the maximum service pressure rating of the valve. In case the actual shutoff pressure specified by the customer is lower than the maximum service pressure rating of the valve, the actuator may be sized to be capable to close against a minimum of 1.1 times the actual shutoff pressure with the customer's approval.(')

9.5 Available air or hydraulic pressure or electric current data must be specified by the customer.

10. SHELL TESTS

10.1 Each Category A Class 125 or 150 diaphragm valve body shall be hydrostatically tested at 1.5 times maximum working pressure specified in the applicable Standard referenced in Table A3, Annex A. Each Category A Class 125 or 150 diaphragm valve bonnet shall be hydrostatically tested with the same pressure as the valve body, when soecified by the customer, and may be tested simultaneously with the body by using a gasket in place of a diaphragm.

10.2 Each Category B diaphragm valve having a service pressure established in accordance with Sub- section 2.2 shall receive a hydrostatic or air shell test in accordance with Table A5, Annex A, with the valve in the full open position. Each bonnet for Category B valves shall be hydrostatically tested with the same pressure as the valve body, when sealed bonnet and testing is soecified by the customer. Bonnet test method shall be at the option of the manufacturer.

Supplementary Information ('I CAUTION: A diaphragm valve displaces fluid during the clos-

ing movement of the diaphragm, therefore, the valve cannot be closed against liquid in a pipe with two closed valves in close proximity, one upstream and one downstream. Excessive actuator force can damage the diaphragms by increasing fluid pressure beyond the capabilities of the diaphragm if the valve is forced to close against such conditions by an oversized actuator.

10.3 Each Category C diaphragm valve having a design pressure-temperature rating established in accordance with Subsection 2.3 shall receive a hydrostatic or air shell test with a minimum test pressure of 1.2 times the design pressure-temperature rating, with the valve in the full open position. Each bonnet for Category C valves shall be hydrostatically tested with the same pressure as the valve body, when sealed bonnet and testing is specified by the customer. Bonnet test method shall be at the option of the manufacturer.

10.4 The duration ofthe shell test shall be as specified in Table AS, Annex A.

10.5 No visible leakage through the pressure bound- ary of the valve is permitted during the shell test.

11. SEAT TESTS

1 1.1 Each Category A Class 125 or 150 valve shall be seat tested for leakage with a seat test pressure of 1 .O times the maximum working pressure rating specified in the applicable pressure rating specified in the applicable Standard referenced in Table A3, Annex A.

1 1.2 Each Category B diaphragm valve having service pressure rating established in accordance with Subsection 2.2 shall be seat tested at pressures shown in Table A5, Annex A.

11.3 Each Category C diaphragm valve having a service pressure rating established per Subsections 2.3,2.4, and 2.5, shall be seat tested for leakage with a seat test pressure of 1 .O times the service pressure rating of the valve.

1 1.4 Testing of the valve from one side is sufficient for valve designs as described in Subsection 1.1. For valves in which the diaphragm is acting in conjunction with a separate or integral disc, the seat test shall be conducted by applying pressure under the closed disc.

4



II 1.5 Valves operated by pneumatic, spring, or electric actuators shall be seat tested at the actual shutoff pressure specified by the customer per Subsec- tion 9.4 (if lower than the service pressure rating of the valve) and irrespective of the pressures given in Table A5, Annex A, and the seat-test requirements of any referenced Standard.

11.6 The duration of the seat test shall be as specified in Table A5, Annex A.

1 1.7 No visible leakage is permitted during the seat test.

12. MARKING

12.1 Marking shall conform to MSS SP-25, except that marking of pressure class is required only for Category A, Class 125 and 150 valves.

12.2 Category B and C, diaphragm valves, in which the diaphragm or bodies may have a maximum service pressure-rating lower than the cold working-pressure rating of the applicable Standards shown in Table A3, Annex A, shall be identified as to the cold working pressure rating. The method of identification shall be at the option of the manufacturer.

12.3 Diaphragm: All diaphragms shall be marked with the name, initials, or easily identifiable trademark of the manufacturer, with the manufacturer’s material identification code and with the nominal valve size to allow the user to determine the diaphragm pressure-temperature rating from the manufacturer’s literature. A code identifjing the year or the year and quarter year of diaphragm manufacture is op- tional.

12.4 Valve Assembly: The assembled valve shall be identified as to model or figure number, diaphragm material identification code in accordance with Sub- section 12.3 and with manufacturer’s name or trademark.
