Titanium Alloy Three-Way Ball Valve

The Titanium Alloy Three-Way Ball Valve is a specialized quarter-turn valve designed for controlling the direction, mixing, or diverting of highly corrosive fluid streams. Utilizing the superior chemical resistance of Titanium, this valve provides critical flow path management in complex chemical and industrial processes.

🔑 Key Functions and Flow Configurations

Three-way ball valves are defined by the bore configuration of the spherical ball, categorized into L-Port and T-Port types:

Configuration	Designation	Function
L-Port	L-shaped Bore	Flow Switching/Isolation: Connects two mutually perpendicular channels, allowing medium flow to be switched between one of two outlets, or isolated completely.
T-Port	T-shaped Bore	Diversion/Mixing/Switching: Can connect all three channels simultaneously (mixing/diversion), or connect any two of the three channels (switching).

Seating Structure: Typically utilizes a two-seat structure for effective sealing, though four-seat structures are available upon request for specific process requirements.

🔬 Corrosion Resistance Principle

The ability of this Titanium Three-Way Ball Valve to resist corrosion is fundamentally dependent on the chemical stability of its “passive oxide film” in the working medium.

High Stability: The passive oxide film provides excellent stability in environments involving neutral, oxidizing, and weakly reducing media. This inherent property makes Titanium ideal for a vast range of chemical applications.
