Valves Standards & Dimensions
CHEMICAL & MECHANICAL COMPOSITION
Prashaant Steel & Alloys is well-known on the international market and is eager to include high-quality Valves Products. Prashaant Steel & Alloys is a producer, supplier, stockiest, and exporter of Valves, and exports the material to global customers at reasonable prices. Valves are made in line with established manufacturing practises, allowing for the most effective use of raw materials.
The valves are used in many industrial, commercial and residential applications. Because of this wide range of applications, there are several key regulatory organizations that provide standards to ensure proper functionality, compatibility, and safety for users. American Petroleum Institute (API), American Society of Mechanical Engineers (ASME), American National Standards Institute (ANSI), ASTM International (FKA American Society for Testing Materials), and Manufacturers Standardization Society (MSS). above were incorporated and headquartered in the United States. Today they have an international reach with their standards used worldwide.
Engineers who design a valve for worldwide use or who use a valve in a product or system design should read the standard documents available from the relevant national and international standards organization.
- The International Organization for Standardization (ISO) is a major international standardization body with several important valve standards.
- The European Committee for Standardization (CEN) creates or approves most of the European standards or Euro standards (EN) and technical specifications for the member countries of the European Union.
- Some valve standards from national standards bodies include ANSI valve standards (USA), BSI valve standards (UK), CSA valve standards (Canada), DIN valve standards (Germany), EEMUA valve standards (UK) and JSA valve standards (Japan) National standards bodies approve in primarily product standards for use in their future countries by other standardization organizations. In addition, they represent national accreditation.
Engineers designing a valve for a particular industrial application or using a valve in a product or system design for a particular industrial application should review the standard documents available from the relevant industrial society organizations. The standards include:
- API valve standards
- ASHRAE valve standards
- ASME BPVC Valves
- ASSE Valves
- AWWA Valves
- ISA Valves
- NFPA Valves
- SAE Valves
American Petroleum Institute (API):
The American Petroleum Institute (API) represents the oil and natural gas industry and creates more than 900 standards that serve as the basis for quality programs that adhere to regulations for production materials and lubricants, and certification programs for storage tanks, pressure vessels and pipes. Inspectors. API publishes reports that include best practices, investigation reports, and specifications for piping, valves, and procedures for the environment.
There are more than 20 API standards covering valve manufacture, use, and safety. 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.

The standard covers the following Category A and B butterfly valves
American Society of Mechanical Engineers (ASME)
The American Society of Mechanical Engineers (ASME) is a professional membership organization focused on engineering, educational, and research issues in the engineering and technology community. In addition to holding technical conferences and development courses, ASME sets internationally recognized manufacturing and industrial standards. The pressure vessels and pipelines subsection includes the design, manufacture and operation of valves and other components as well as pressure vessels.
ASME publishes hundreds of standards, and many of them apply to a particular instrument in a particular application. Valve standards are listed below.

ASME BPVC Code
The ASME BPVC Code sets out the safety rules for the design, manufacture, inspection, testing and operation of boilers and pressure vessels and components of nuclear power plants during construction. The purpose of these rules is to create a margin for service degradation. The ASME BPVC code or standards are updated every two years to reflect advances in design and material based on evidence of experience. The ASME BPV Certificate Scopes (BPV Seal Holder Scopes) list the authorized activities for each type of ASME certificate or seal. ASME seals or approval certificates are required for safety or pressure relief valves in boilers, pressure vessels and pressure equipment, such as:
- ASME High Pressure Vessel Safety Valve Accreditation Set
- ASME Pressure Vessel Safety Valve Accreditation Set
- ASME V Stamp – Power Boiler Safety Valves
- ASME HV Stamp – Heating Boilers Safety Valves

National Board of Boiler and Pressure Vessel Inspector (NBBI):
The National Board of Boiler and Pressure Vessel Inspectors (NBBI) created the National Board Inspection Code (NBIC) in 1946, which serves as one of the primary tools for compliance assurance. 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).
