American standard titanium butterfly valve

Product features

Butterfly valve adopts the theme of the titanium material titanium is a metal with high chemical activity. It is, however, to many corrosive medium are present a special excellent corrosion resistance. Reason is have very good affinity, titanium and oxygen to react with oxygen and generated on the surface layer of strong and dense blunt oxide thin films. Titanium butterfly valves in the atmosphere, fresh water, sea water, high temperature steam, almost no corrosion. Titanium butterfly valve is suitable for flow control. Because titanium butterfly valve in the pipeline pressure loss is bigger, about three times the gate valve, so when choosing titanium butterfly valves, piping system is affected by pressure loss should be considered, but should also consider closing butterfly plate consistence of pipeline medium under pressure. In addition, the choice of resilient seated occasion must also consider the high performance ptfe (graphite) composite plate sealing ring material at high temperature on the operating temperature limit. Working condition of titanium valve material selection, should fully consider the working temperature of corrosive medium, medium composition, concentration of each ingredient, moisture content and so on four aspects.
