Three-way Internal Thread Butterfly Handle Ball Valve

Engineered for precise flow diversion in compact spaces, this three-way ball valve features internal threading for secure connections and a low-profile butterfly handle for quick 90° operation. Constructed in corrosion-resistant alloys, it ensures zero-leakage performance in high-pressure fluid systems. Ideal for directional control applications requiring space efficiency, its robust design minimizes maintenance while maximizing service life. Certified to international quality and safety standards.

1、Key Features
• Three-way (L-port) flow configuration for diversion/mixing
• Internal threaded ends (NPT/BSPP) for compact installations
• Low-torque butterfly handle with visual position indicator
• Double-sealed stem with anti-blowout design
• Full port design for minimal pressure drop


2、Performance Advantages
• 40% faster operation compared to handwheel valves
• Zero-leakage shutoff per ANSI/FCI 70-2 Class VI
• Reduced installation footprint with internal threading
• Interchangeable seats/stems for simplified maintenance

• Fire-safe design per API 607 (optional)
