Overview


The Heavy-Duty Stainless Steel 2-Piece Thread Ball Valve is a robust flow control solution designed for high-pressure, high-corrosion industrial applications. Constructed from 316 stainless steel, this valve features NPT threads (ANSI B1.20.1), a full-bore design, and a heavy-duty body, ensuring reliable performance in harsh environments where durability and leak resistance are non-negotiable.


Features


Industrial-Grade Construction:

316 stainless steel body (ASTM A316) with a wall thickness 20% thicker than standard valves, capable of withstanding 2,000 PSI working pressure and 10,000 cycle life.

Heat-treated stem (HRC 38-42) and reinforced ball (full-diameter through-hole) reduce wear in high-frequency operation, ideal for automated systems.

Full-Bore Flow Performance:

Unrestricted flow path (bore equal to pipe diameter) minimizes pressure loss, achieving Cv values 15% higher than competitive models, critical for high-volume fluid transfer.

PTFE seat with metal backup ring provides bubble-tight shutoff (API 598) even after 5 years of continuous use in abrasive media.

Threaded Connection Strength:

NPT male/female threads (ANSI B1.20.1) with optional sealant grooves, compatible with schedule 80 pipes and heavy-duty fittings, torque-rated to 80 N·m for 2" valves.

Magnetic particle inspected (MPI) for welds (on welded components) to ensure zero defects in critical applications.

Extreme Environment Resistance:

Temperature range: -40°C to 260°C (RPTFE seat), suitable for cryogenic liquefied natural gas (LNG) lines and hot oil pipelines.

Compliant with NACE MR0175 and ISO 15156-3 for sour gas service, making it ideal for oil fields with high H2S concentrations.


Application


Ideal for mission-critical industrial systems:

Petroleum Refineries: On/off control in crude oil distillation units and catalyst transfer lines, with 316 stainless steel resisting sulfuric acid and naphtha corrosion.

Chemical Processing: Handling concentrated alkalis and solvents in pharmaceutical manufacturing, meeting cGMP standards for cleanable surfaces (Ra ≤0.8μm).

Power Generation: High-pressure feedwater lines in nuclear plants, with 316 stainless steel complying with ASME BPVC Section III for nuclear-grade components.

Mining & Minerals: Slurry and tailings pipelines, with heavy-duty construction enduring abrasive particle erosion and high-pressure surges.


FAQ


Q: Can this valve be used for throttling applications?

A: No, ball valves are designed for on/off use; consider a globe valve for flow regulation.

Q: What is the recommended maintenance for high-cycle applications?

A: Lubricate the stem and ball with food-grade grease every 6 months and inspect seats for wear using a borescope.

Q: Are there options for permanent anti-corrosion coating?

A: Yes, optional electroless nickel plating (5-8μm) enhances surface hardness and corrosion resistance in marine and salt-spray environments.

Q: Can the valve be certified for use in oxygen systems?

A: Yes, with proper cleaning and degreasing (complying with ASTM G93), suitable for oxygen service up to 200 bar.
