Titanium Alloy Wedge Gate Valve

The Titanium Alloy Wedge Gate Valve is a flanged, rising stem valve engineered for absolute on/off isolation in critical chemical processes. By constructing the body and internal components from high-grade Titanium alloy, the valve achieves exceptional resistance to corrosion, ensuring maximum reliability and safety where conventional materials fail.

🔑 Key Design and Performance Features

Isolation Function: Designed for simple, reliable on/off service (full open or full closed).
Wedge Gate Design: Utilizes a resilient wedge gate structure, which provides tight, positive shutoff.
Rising Stem: The stem rises visibly above the handwheel when the valve is opened, providing clear visual indication of the valve position.
Superior Sealing Surface: The critical valve seat sealing surface is made of Titanium Alloy, ensuring a metal-to-metal contact with the gate for long-term tightness.
Material Science Advantage: Titanium’s exceptional resistance stems from its high affinity for oxygen. A robust, dense passive oxide film forms instantaneously on its surface, providing a highly protective barrier against many corrosive media.
