Valve Standards

Valves are used in many applications throughout the industrial, commercial, and residential industries. Due to this wide range of uses, there are several major regulatory organizations which provide standards to ensure proper functionality, compatibility and safety for users.

The major standard organizations include the American Petroleum Institute (API), the American Society of Mechanical Engineers (ASME), the American National Standards Institute (ANSI), the ASTM International (FKA American Society for Testing Materials), and the Manufacturers Standardization Society (MSS). While the organizations above were founded and are headquartered in the U.S., they have international reach today with their standards used around the world.

Engineers designing a valve for or using a valve in a product or system design for global use, should review the standard documents available from international and the applicable national standard organization.

Engineers designing a valve for or using a valve in a product or system design for specific industrial application, should review the standard documents available from applicable industrial society organizations. Some industry specific valve standards include:

Valve standards from safety focused organizations include NFPA Valve Standards and UL Valve Standards. Many of the standards from the other industry specific, national or international standards organization also pertain to safety aspects of products or assuring products perform safety in their applications without loss of life or damage to property.

American Petroleum Institute (API)

The American Petroleum Institute (API) represents the oil and natural gas industry. They produce more than 900 standards that serve as the basis for quality programs that maintain regulations for production material and lubricants, and certification programs for storage tanks, pressure vessels, and piping inspectors. API publishes reports that include recommended practices, research reports, and specifications on pipelines, valves and environmental procedures.

There are more than 20 API standards addressing the manufacturing, application and safety of valves. Specific standards include:

  • API SPEC 6D – Specification for Pipeline Valves. API Specification 6D is an adoption of ISO 14313: 1999, Petroleum and Natural Gas Industries– Pipeline Transportation Systems-Pipeline Valves. This International Standard specifies requirements and gives recommendations for the design, manufacturing, testing, and documentation of ball, check, gate, and plug valves for application in pipeline systems.

  • API STD 598 – Valve Inspection and Testing. The standard covers inspection, supplementary examination and pressure test requirements for both resilient-seated and metal-to-metal seated gate, globe, plug, ball, check and butterfly valves. Pertains to inspection by the purchaser and to any supplementary examinations the purchaser may require at the valve manufacturer’s plant.

  • API STD 527 – Seat Tightness of Pressure Relief Valves R(2002). Describes methods of determining the seat tightness of metal and soft-seated pressure relief valves, including those of conventional, bellows and pilot-operated designs.

  • API STD 602 – Steel Gate, Globe, and Check Valves for Sizes NPS 4 (DN 100) and Smaller for the Petroleum and Natural Gas Industries-Ninth Edition

  • API STD 607 – Fire Test for Quarter-turn Valves and Valves Equipped with Nonmetallic Seats – Sixth Edition

  • API STD 609 – Butterfly Valves: Double-flanged, Lug- and Wafer-type-Seventh Edition This standard covers design, materials, face-to-face dimensions, pressure-temperature ratings, and examination, inspection and test requirements for gray iron, ductile iron, bronze, steel, nickel-based alloy, or special alloy butterfly valves that provide tight shutoff in the closed position. The standard covers the following Category A and B butterfly valves.

More information on API standards can be found on the American Petroleum Institute website.

American Society of Mechanical Engineers (ASME)

The American Society of Mechanical Engineers (ASME) is a professional member organization focused on technical, educational and research issues of the engineering and technology community. In addition to hosting technical conferences and development courses, ASME sets internationally recognized industrial and manufacturing standards that enhance public safety. The subdivision of Pressure Vessels and Piping covers the design, fabrication and operation of valves and other pressure-bearing components and vessels.

ASME publishes hundreds of standards, and many of them are for a specific instrument in a specific application. Some examples of valve standards are listed below.

  • ASME F1020– Standard Specification for Line-Blind Valves for Marine Applications

  • ASME B16.33 – EN-Manually Operated Metallic Gas Valves for Use in Gas Piping Systems up to 125 PSI (Sizes NPS 1/2 Through NPS 2)

  • ASME B16.34 INTERPRETATIONS – EN-Interpretations to B16.34-1996 Valves – Flanged Threaded and Welding End-Includes Interpretation No. 2

  • ASME B16.10 INTERPRETATIONS – EN-Interpretations to B16.10-1992 Face-to-Face and End-to-End Dimensions of Valves-Includes Interpretation No. 1


The ASME BPVC Code establishes the rules of safety governing the design, fabrication, inspection, testing, and operation of boilers andpressure vessels, and nuclear power plant components during construction. The objective of these rules is to provide a margin for deterioration in service. The ASME BPVC code or standards are updated every two years to include advancements in design and material based on the evidence of experience. The ASME BPV Certificate Scopes (BPV Stampholder Scopes) list the authorized activities for each type of ASME certificate or stamp. Several ASME stamps or certificates of authorization are required for pressure relief or safety valves on boiler, pressure vessel and pressure equipment such as:

ASTM International

ASTM International, originally known as the American Society for Testing Materials (ASTM), is the largest voluntary standards development organization in the world. Throughout 67 volumes in 16 different areas, the organization has included standards in test procedures for determining chemical composition and performance metrics.

ASTM develops valve standards for valves made of a particular material and for a specific application. Examples of their standards include:

  • ASTM A961/A691M – Standard Specification for Carbon and Alloy Steel Pipe, Electric-Fusion-Welded for High-Pressure Service at High Temperatures.

  • ASTM B61 – Standard Specification for Steam or Valve Bronze Castings.

  • ASTM F1030 – Standard Practice for Selection of Valve Operators.

  • ASTM F1802 – Standard Test Method for Performance Testing of Excess Flow Valves.

This code has been adopted by most states and cities in the United States, all Canadian provinces and someUS regulatory agencies, including the US Department of Transportation. It is the only code recognized worldwide for the in-service inspection of repairs and alterations of boilers and pressure vessels (BPV).

  • VRStamp – The National Board offers theCertificate of AuthorizationandRsymbol stamp for the repair pressure relief valves. The requirements the supplier must meet to be authorized are described in NBIC standards for Repairs and Alterations – NBBI NB-23 PART 3, Section 1.
