Why Valve Standards Matter

In marine and industrial environments, valves serve a critical role in regulating the flow of gases, liquids, and other media. But selecting the right valve isn’t just about the type—industry standards also play a major role. Whether you're sourcing a gate valve for a ship’s ballast system or a globe valve for a petrochemical plant, it’s essential to understand which standards your project requires.

At Aik Soon Hardware Pte Ltd, we stock and distribute valves built to major global standards: API (American Petroleum Institute), JIS (Japanese Industrial Standards), and DIN (Deutsches Institut für Normung). These standards ensure safety, performance, and compatibility in critical operations across sectors like marine, offshore, oil & gas, and general industry.

1. API Standards – Built for High-Stress Environments

The American Petroleum Institute (API) sets some of the most stringent standards in the world for oil, gas, and petrochemical equipment.

• Common Standards: API 600 (gate valves), API 602 (small forged steel valves), API 6D (pipeline valves)

• Applications: Oil rigs, refineries, offshore platforms, pipeline systems

• Why It Matters: Valves built to API standards are engineered for high-pressure, high-temperature applications. They often undergo strict testing and certification, making them a top choice in safety-critical environments.

👉 At Aik Soon Hardware, we supply API-compliant valves for clients in the oil & gas and offshore marine sectors, ensuring performance and regulatory compliance.

2. JIS Standards – Optimized for Asian Marine and Industrial Systems

JIS (Japanese Industrial Standards) are widely used in Asia-Pacific, especially in shipbuilding and marine engineering.

• Common Standards: JIS 5K, 10K, 16K flanges and pressure ratings

• Applications: Marine vessels, shipyards, engine cooling systems, seawater piping

• Why It Matters: JIS valves are designed with metric dimensions, making them compatible with Japanese and regional equipment. They are often preferred by shipowners and marine engineers operating Asian-built vessels.

✅ Aik Soon Hardware carries a wide range of JIS marine valves—ready-stocked in Singapore—to meet the needs of regional shipbuilders and maritime operators.

3. DIN Standards – Precision Engineering from Europe

DIN (Deutsches Institut für Normung) standards originate from Germany and are recognized across Europe and global industrial markets.

• Common Standards: DIN 3202 (face-to-face dimensions), DIN EN 558, DIN 3352 (gate valves)

• Applications: Industrial plants, chemical processing, water treatment, HVAC

• Why It Matters: DIN valves are known for precision, durability, and modular design. They're commonly used in European-manufactured systems and in industrial environments requiring exact specifications.

📦 Aik Soon Hardware supplies DIN-compliant valves in a range of materials and pressure classes for industrial clients seeking quality and interoperability with European systems.

How to Choose the Right Valve Standard

When selecting a valve, consider the following:

• ✅ Project specifications – Check if the client or project requires a specific standard.

• ✅ Geographic location of equipment origin – European systems lean toward DIN, Asian vessels toward JIS, and offshore systems toward API.

• ✅ Application and media type – High-risk applications may require stricter standards like API.

• ✅ Compatibility with existing piping and flanges – Ensure dimensional match to avoid costly retrofitting.
