HF5(ST) BALL VALVE FOR STEAM SERVICE

Features

This model has been developed specially for steam service(1MPa, 2MPa). These are using at steam line for many kinds of fields(chemical, food, air conditioning and etc). 

●This model is sdopted double seal design with expansion graphite and stem o-ring seal(for 1MPa) for leakage protection at gland part.

●Ball seat of 1MPa is adopted MAXTITE PTFE material, and 2MPa is adopted special carbon filled PTFE has higher heat resistance for down stream side.
