Triple Eccentric Butterfly Valve is widely used in industrial field because of its zero leakage and high temperature resistance. Its excellent performance comes from its internal structure. Many valves claim to have fire-resistant construction, but most of them use hard and soft double seat construction in order to reduce leakage, which is dangerous. Because incomplete combustion of the soft seal seat in fire will cause stress, temperature difference and deformation of the metal support seat, which will lead to the failure of the fire-resistant function. Therefore, at present, Europe and the United States are gradually excluding such inappropriate fire-resistant valves. Because Tritrc is zero leakage, it does not need the assistance of soft seals, is a true essential refractory structure, and has obtained API 607, API6FA and BS6755Part2 certificates of fire inspection qualification. This ensures that Tritec can be used in various dangerous areas such as petroleum, petrochemical, etc. The use of valves in conservative Britain, in key parts of its North Sea oilfield, is exemplified by the fact that almost all of them are covered by Tritec.
In many Asia-Pacific countries, due to the limitations of domestic valve design and manufacturing level, as well as the influence of traditional textbooks, the bias against disc valves is still very large. At the same time, the advanced developed industrial countries in Europe and America are vigorously promoting and actively using disc valves. The reason is simple, the disc valve is no longer what it used to be.
The Tri-eccentric disc valve can withstand up to 2500 pounds of pressure, low temperature resistance to – 196 degrees C, up to 700 degrees C, zero leakage of seal, and control ratio of up to 100:1. Disc valves can be safely used in all kinds of rigorous and critical process control pipelines, whether on-off valves or control valves, as long as they are properly selected. Also, the cost is low.
