Product Description

Product Description

NAI LOK Ultra High Purity EP Grade Stainless Steel 316L Ball Valve Electro Polish 6 Inch 3 PCS Orbital Welded UHP Ball Valve
High Purity 316/316L Stainless Steel 3-Piece Ball Valve - Engineered for Critical Service

Product Title: High Purity EP Electropolished BA Bright Annealing 3-Piece Ball Valve | 3/4" & 2" | CF8M/CF3M | With Purge Port | Cleaned for Oxygen Service (CFOS)

Subtitle: Features Full Port High Flow Design & Integrated Tee Assemblies. Ideal for Semiconductor, PV, Bio-Pharm, and High-Purity Gas Systems.

Ultra-High Purity Internals: Internal wetted surfaces are Electropolished (EP) to a mirror-like finish, minimizing particulate generation and adsorption for superior contamination control.

Superior Material & Performance: Constructed from CF8M (316 SS) and CF3M (316L SS) for excellent corrosion resistance. Rated for 1000 WOG, suitable for water, oil, and gas applications.

Designed for Purge & Sampling: Features a dedicated Purge Port for easy system purging, media sampling, or seat leakage testing, ensuring system safety and media integrity.

High Flow, Low Pressure Drop: Full-Port Design provides a bore diameter matching the pipe ID, maximizing flow capacity and minimizing pressure loss for enhanced system efficiency.

Modular & Integrated Flexibility: Available in various Integrated Tee Valve Assembly configurations using high-quality NAI-LOK tube and tube fittings, simplifying system design and reducing potential leak points.

Long Life & Easy Maintenance: 3-Piece Construction allows for easy in-line maintenance and component replacement without removing the valve from the pipeline. Floating Ball design ensures bubble-tight, positive shut-off and delivers high cycle-life performance.
