In global industrial production, engineering construction, and multinational projects, valves are core components of piping systems. Different countries and industries use their own standard systems, such as American Standards (ANSI/ASME/API), German Standards (DIN), European Standards (EN), and Russian Standards (GOST). Choosing valves that conform to these standard systems ensures the safe and reliable operation of piping systems, while also ensuring interchangeability and ease of maintenance.
As a leading global valve supplier, WEIZIDOM offers valve products covering multiple standard systems, widely used in oil and gas, water treatment, power plants, mining, and municipal engineering projects.
Standard system valves are designed and manufactured according to international or national standards, offering the following advantages:
Uniform dimensions and high interchangeability: Facilitates replacement and maintenance.
Reliable performance: Rigorous testing ensures long-term safe operation.
Adaptable to multiple operating conditions: Can be selected based on pressure, temperature, medium, and flow requirements.
Main standard systems supported by WEIZIDOM:
| Standards System | Applicable Regions | Main Applications |
| API | International Oil and Gas Industry | Key valves in oil and gas projects, including high-pressure ball valves, gate valves, and butterfly valves. |
| ANSI | US and North American Engineering | American standard dimensions and pressure ratings, suitable for oil and gas and chemical projects. |
| DIN | Germany and Europe Engineering | Advanced engineering design and strong corrosion resistance. |
| EN | European and International Engineering | European standards, internationally recognized. |
| NFPA | International Fire Protection Industry | Fire protection system valve standards. |
| GOST | Russia and CIS Market | Meets project specifications in Russia, Kazakhstan, Belarus, and other countries, suitable for oil and gas, chemical, and municipal engineering projects. |
📌 Note: WEIZIDOM can provide valve products that comply with other international standards (such as BS, ISO, JIS, etc.) according to customer project requirements. Please consult our sales team for details.
WEIZIDOM valves cover a variety of types, adapting to different standard systems and engineering needs:
