The JNV Series High Purity High Pressure Stainless Steel Needle Valve is designed for precise natural gas flow control in demanding industrial environments. 

Material & Construction
Made from 316L stainless steel or specialized alloys (e.g., Monel, Hastelloy), ensuring corrosion resistance and compatibility with high-purity gas systems
Internal surfaces undergo specialized treatments to minimize gas adsorption and particle generation

Pressure & Temperature Performance
Operating pressure up to 35 MPa (5000+ PSI), suitable for ultra-high-pressure natural gas applications
Temperature range: -60°C to 649°C, with reinforced graphite packing for extreme conditions

 

 

 

This valve series combines ultra-high-pressure resilience with high-purity gas compatibility, ensuring reliability in critical natural gas flow management .

Flow Control & Leakage Standards
Precision needle-shaped valve stem for fine flow adjustment, achieving 1 mL/h-level accuracy
Strict internal/external leakage control to meet high-purity gas system requirements

Applications
Natural gas compression stations, CNG refueling systems, and high-pressure gas pipelines
Petrochemical, semiconductor, and pharmaceutical industries requiring contamination-free flow regulation

Design Options
Available in sizes from 1/4" to 1", with threaded or flanged connections
Customizable configurations for specific pressure or media compatibility needs
