Purpose of Jacketed Valve
Posted on February 25, 2013

Main purpose for using of Jacketed Valve is to maintain continuous free flow of pipe line in liquid or flowable mode by the help of Jacket surrouing valve body. Wherever in industries material solidify at normal temperature like Sulfur, Asphalt, Coaltar, Bitumen, Visous media etc, their mostly pipe line, valves & pumps modify by Steam or Hot Oil Jacket.

Mostly all Jacketed valve flanges are one size higher due to proper easy bolting clearance at flange. Same size as line of flange valve also can do manufacturing but in that case jacket will be half / partial type.
