Clean Gas Applications in High-Tech Environments

As the demand for ultra-clean environments grows in industries like semiconductors, electronics, and biotech, clean gas piping systems play a critical role in maintaining process purity and operational safety. Valves used in these systems must meet stringent standards to avoid contamination, leakage, or material degradation.

Challenges and Requirements for Clean Gas Valves

Clean gases such as nitrogen, argon, oxygen, and hydrogen are widely used in wafer fabs, laboratories, and advanced manufacturing environments. Valves in these systems must ensure:

• Minimal particle shedding
• Corrosion resistance (typically 316L stainless steel)
• Dead-leg-free design to avoid contamination
• BA or EP surface treatment
• Oxygen cleaning and helium leak tested

Juhan Valve's Stainless Steel Ball Valves for Clean Applications

Juhan Valve Co., Ltd. specializes in precision stainless steel valves tailored for clean gas systems. Our stainless steel ball valves are used in semiconductor plants, flat panel display factories, and high-purity gas distribution lines. Features include:

• Forged 316L stainless steel bodies
• Internal surface roughness ≤ Ra 0.4 μm (BA-grade)
• Oil-free and oxygen-cleaned options available
• Available with VCR ends, orbital weld, or high-purity tube connections
• 100% leak tested with nitrogen or helium

Technical Insight: What Is BA-Grade Piping?

BA (Bright Annealed) grade stainless steel piping and valves undergo bright annealing to achieve a highly clean and corrosion-resistant internal surface. Key characteristics include:

• Internal roughness ≤ Ra 0.4 μm
• Electropolishing available for even higher purity
• Designed for ultra-pure gas and chemical systems
• Fully cleaned, leak-tested, and particle-controlled packaging

Conclusion

In clean gas systems where purity, stability, and safety are paramount, valves must meet the highest standards. Juhan Valve remains committed to providing high-performance stainless steel valves that meet the technical and cleanliness demands of the electronics and semiconductor industries.
