Three-way Internal Thread Ball Valve

The Three-Way Internal Thread Ball Valve is a versatile flow control solution designed for complex pipeline systems requiring multi-directional fluid diversion. Featuring a compact L-port or T-port configuration, this valve enables precise flow distribution, mixing, or shut-off in a single unit. Its internal threaded (NPT/BSP) connections ensure easy installation, while the stainless steel (304/316) construction provides durability in high-pressure and corrosive environments. Ideal for chemical processing, HVAC systems, and water treatment plants, this valve meets ISO 9001 and SIL standards, offering reliable performance for critical industrial applications.

1. Key Features
• Three-way design (L-port/T-port) for flow diversion, mixing, or shut-off.
• Internal threaded ends (NPT/BSP) for leak-proof pipe connections.
Stainless steel body (304/316) for corrosion resistance.
• PTFE seats ensure tight sealing and low torque operation.
• Locking handle (optional) for secure position control.


2. Advantages
• Space-saving design replaces multiple valves in complex systems.
• Smooth 90° operation for quick flow direction changes.
• Low maintenance with self-lubricating seals.
• Wide compatibility with water, oil, gas, and mild chemicals.
