Stainless Steel 304 316 L type T type Threaded three-Way Ball Valve

Stainless Steel Three-Way Ball Valve

Key Features

1. Material Construction
   • Body & Components: Made of high-grade stainless steel (e.g., 304, 316, or 316L), offering excellent corrosion resistance in harsh environments (e.g., chemicals, seawater, high-temperature media).
   • Seals: Equipped with PTFE, RPTFE, or metal seats for reliable sealing under high pressure and temperature conditions.
2. Flow Path Configurations
   • L-Port (90° Diversion): Redirects flow from one port to another at a 90° angle, suitable for simple switching applications.
   • T-Port (3-Way Mixing/Diverting):
     • 3-Way Diverter: Splits flow from one inlet to two outlets.
     • 3-Way Mixer: Combines flow from two inlets into one outlet.
3. Operational Mechanism
   • 90° Rotation: The ball rotates 90° to open, close, or redirect flow, enabling quick and precise control.
   • Manual/Automated Actuation: Supports manual lever operation, pneumatic, or electric actuators for remote or automated control.
4. Design Variants
   • Full-Bore Design: Minimizes pressure drop by maintaining consistent flow diameter.
   • Reduced-Bore Design: Cost-effective option with smaller ball bore, suitable for applications where flow restriction is acceptable.

Technical Specifications

• Pressure Rating: Up to 6000 PSI (414 bar), depending on model and material.
• Temperature Range: -20°C to 220°C (standard seals); higher with specialized materials.
• Port Sizes: Available in sizes from DN15 (1/2") to DN300 (12"), with larger sizes customizable.
• Connection Types: Threaded (NPT/BSP), flanged (ANSI/DIN/JIS), or welded ends for versatile installation.

Applications

1. Chemical Processing: Controls the flow of corrosive chemicals, acids, and solvents.
2. Water Treatment: Manages water distribution, mixing, and diverting in filtration systems.
3. Oil & Gas: Regulates fluid flow in pipelines, blending systems, and sampling points.
4. Food & Beverage: Used in hygienic processes for diverting or mixing liquids (e.g., dairy, brewing).
5. HVAC Systems: Directs hot/cold water or steam flow for temperature control.
6. Pharmaceuticals: Ensures sterile flow management in drug production and CIP (Clean-in-Place) systems.

Advantages

• Corrosion Resistance: Stainless steel construction withstands aggressive media.
• Low Maintenance: Self-lubricating ball design reduces wear and extends service life.
• Leak-Proof Sealing: High-performance seals prevent external leakage.
• Compact Design: Space-saving alternative to multiple valves in complex systems.
• Quick Operation: 90° turn enables rapid flow path changes.

Selection Considerations

• Flow Requirement: Choose T-port for mixing/diverting or L-port for simple redirection.
• Pressure/Temperature: Select materials and seals rated for your system’s operating conditions.
• Actuation Needs: Decide between manual, pneumatic, or electric actuation based on automation requirements.
• Certifications: Ensure compliance with industry standards (e.g., ATEX, FDA, NSF) for specific applications.
