Application of titanium valve in aerospace field and its materials

The high strength and low density of titanium and titanium alloys provide a broad space for their wide application in the aerospace field. Titanium alloys and their valve products are widely used in the aerospace field. Only in terms of the types of valves used, they mainly involve regulating valves, needle valves, etc., and more small-sized and non-standard design valves are mainly used. In the aviation field, the application of titanium alloy and its valve products is not only wide but also huge. Titanium alloy valves are widely used in various pipelines on aircraft. The types of valves involve regulating valves, globe valves, check valves, needle valves, plug valves, ball valves, butterfly valves, etc. The titanium materials used for valves include pure titanium ( Such as ASTMB367C2) and titanium alloy Ti-6AI-4V (ASTMB381F5), Ti-6AI-6V-2Sn, Ti-6A1-2Sn-4Zr-2Mo, Ti-6A1-2Sn-4Zr-6Mo, etc., but pure titanium and Titanium Threaded Forged Fitting Ti-6A1-4V is more common. The titanium valve used in the aviation field uses Ti-6AI-4V as its fastener material in the United States, and BT16 in Russia.
