Main Parts and Materials:

Key Product Features:

Corrosion-Resistant Construction: The body, bonnet, and disc are manufactured from CF8 cast stainless steel, providing excellent resistance to rust and chemical attack compared to standard cast iron.
PTFE Sealing System: Utilizing PTFE (Teflon) for both the stem packing and body gasket ensures low-friction operation and a tight seal, minimizing maintenance and preventing fugitive emissions.
Rising Stem Design (OS&Y): The outside screw and yoke configuration provides clear visual indication of the valve position (open or closed) and keeps the stem threads protected from the flow medium.
Precision Casting: The CF8 components are precision cast to ensure dimensional accuracy and smooth flow passages, reducing pressure drop across the valve.

Applications:

Ideal for Chemical Processing, Food & Beverage, Pharmaceutical Manufacturing, Marine Systems, and High-Purity Water/Steam Networks. Specifically suited for environments where corrosion resistance, hygiene, and strict adherence to international standards are required.
