HF5(ST)

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.
