Differences Between Valve Standards: API, DIN, JIS, and GB
When purchasing industrial valves, one of the most important considerations is the manufacturing standard. Different countries and regions have established their own valve standards to ensure safety, performance, and compatibility. Understanding these standards helps buyers select the right valves for their projects.
1. API Standard (American Petroleum Institute)
The API standard is widely used in the oil & gas industry worldwide.
Main features: Focus on safety, performance, and high-pressure resistance.
Common standards: API 600 (Gate Valves), API 602 (Compact Steel Valves), API 6D (Pipeline Valves).
Application: Oilfield pipelines, refineries, petrochemical plants.
2. DIN Standard (German Institute for Standardization)
The DIN standard is common in Europe, especially Germany.
Main features: Precise dimensions, strong material requirements, durable design.
Common standards: DIN 3352 (Gate Valves), DIN 3202 (Face-to-Face Dimensions).
Application: Power plants, water treatment, and industrial facilities in Europe.
3. JIS Standard (Japanese Industrial Standard)
The JIS standard is widely used in Japan and Southeast Asia.
Main features: Suitable for low-to-medium pressure systems, compact and economical design.
Common standards: JIS 10K, 16K (Flange & Pressure Ratings).
Application: Marine industry, water pipelines, general industrial use.
4. GB Standard (Chinese National Standard)
The GB standard is the Chinese National Standard, also widely accepted in Asian markets.
Main features: Covers a broad range of industrial applications, cost-effective, with improving global recognition.
Common standards: GB/T 12234 (Gate Valves), GB/T 9113 (Flanges).
Application: Power, chemical, water supply, and infrastructure projects in China and Belt & Road regions.
5. Key Differences Between Standards
| Standard | Region | Pressure Rating | Applications | Advantages |
|---|---|---|---|---|
| API | USA / Global | High Pressure | Oil & Gas | Safety, reliability |
| DIN | Europe | High / Medium | Industrial, Power | Precision, durability |
| JIS | Japan / Asia | Low / Medium | Marine, Water | Compact, economical |
| GB | China / Asia | Medium / Broad | Power, Chemical | Cost-effective, wide range |
Different valve standards are designed to meet regional needs and industry requirements. When choosing valves, it is crucial to consider:
The region of use (e.g., Europe, Asia, Middle East, Americas)
The industry (e.g., oil & gas, power, water, marine)
The operating pressure and temperature
By matching the correct standard, buyers can ensure safe, efficient, and compatible valve operation in their projects.
