Big knife valve

Stainless Valve has introduced its 48″ big knife valve. The company has said it has supplied two 48″ valves made in duplex stainless steel 2205 for flue gas applications. This material has higher strength and corrosion resistance than the austenitic stainless steels. When there is some accumulation of solids in the valve cavity the bottom of the valve can be opened so that the valve cavity can be cleaned out without taking the valve out of the line. This saves time and keeps the plant working for a longer time. To prevent the deposit of sticky substances, the valve automatically closes to a predetermined percentage of opening every 24 hours and then opens again completely.
