    404.5 Valves

    404.5.1 General. Steel valves conforming to standards

    and specifications listed in Tables 423.1-1 and 426.1-1 may be used. These valves

    may contain certain cast, malleable, or wrought iron parts as provided for in API 6D.

    Cast iron valves conforming to standards and specifications listed in Tables 423.1-1

    and 426.1-1 may be used for pressures not to exceed 250 psi (17 bar). Care shall be

    exercised to prevent excessive mechanical loading (see para. 404.4.8.3).

    Working pressure ratings of the steel parts of steel valves are applicable with the

    temperature limitations of -20F (-30C) to 250F (120C) (see para. 401.2.2.4).

    Where resilient, rubber-like, or plastic materials are used for sealing, they shall be

    capable of withstanding the fluid, pressure, and temperature specified for the piping

    system.

    404.5.2 Special Valves. Special valves not listed in Tables 423.1-1 and 426.1-1 shall be

    permitted, provided that their design is of at least equal strength and tightness and

    they are capable of withstanding the same test requirements as covered in these

    standards, and structural features satisfy the material specification and test procedures

    of valves in similar service set forth in the listed standards.

    831.1 Valves and Pressure-Reducing Devices

    831.1.1 Valves Without Threads. Valves shall conform to standards and

    specifications referenced in this Code and shall be used only in accordance

    with the service recommendations of the manufacturer.

    (a) Valves manufactured in accordance with the following standards may be

    used: see previous list.

    (b) Valves having shell (body, bonnet, cover, and/or end flange) components

    made of cast ductile iron in compliance with ASTM A395 and having

    dimensions conforming to ASME B16.1, ASME B16.33, ASME B16.34,

    ASME B16.38, ASME B16.40, or API 6D/ISO 14313 may be used at pressures

    not exceeding 80% of the pressure ratings for comparable steel valves at their

    listed temperature, provided the pressure does not exceed 1,000 psig (6 900

    kPa), and welding is not employed on any ductile iron component in the

    fabrication of the valve shells or their assembly as part of the piping system.

    (c) Valves having shell components made of cast iron shall not be used in gas

    piping components for compressor stations.

    Natural and Other Gas by Pipeline

    192.145 Valves. Link to an amendment published at 80 FR 181, Jan. 5, 2015.

    (a) Except for cast iron and plastic valves, each valve must meet the minimum

    requirements of API 6D (incorporated by reference, see 192.7), or to a national or

    international standard that provides an equivalent performance level. A valve

    may not be used under operating conditions that exceed the applicable pressure-

    temperature ratings contained in those requirements.

    (b) Each cast iron and plastic valve must comply with the following:

    (1) The valve must have a maximum service pressure rating for temperatures that

    equal or exceed the maximum service temperature.

    (2) The valve must be tested as part of the manufacturing, as follows:

    (i) With the valve in the fully open position, the shell must be tested with no

    leakage to a pressure at least 1.5 times the maximum service rating.

    (ii) After the shell test, the seat must be tested to a pressure not less than 1.5

    times the maximum service pressure rating. Except for swing check valves, test

    pressure during the seat test must be applied successively on each side of the

    closed valve with the opposite side open. No visible leakage is permitted.

  • Federal Codes for Transportation of

    Natural and Other Gas by Pipeline

    (iii) After the last pressure test is completed, the valve must be operated through its

    full travel to demonstrate freedom from interference.

    (c) Each valve must be able to meet the anticipated operating conditions.

    (d) No valve having shell (body, bonnet, cover, and/or end flange) components

    made of ductile iron may be used at pressures exceeding 80 percent of the

    pressure ratings for comparable steel valves at their listed temperature. However, a

    valve having shell components made of ductile iron may be used at pressures up to

    80 percent of the pressure ratings for comparable steel valves at their listed

    temperature, if:

    (1) The temperature-adjusted service pressure does not exceed 1,000 p.s.i. (7 Mpa)

    gage; and

    (2) Welding is not used on any ductile iron component in the fabrication of the valve

    shells or their assembly.

    (e) No valve having shell (body, bonnet, cover, and/or end flange) components

    made of cast iron, malleable iron, or ductile iron may be used in the gas pipe

    components of compressor stations.
