Re: [MW:13538] Valve Back Seat Test

Dear Mr.Gopi..
 
The contact area between the stem & gland packing is known as  back seat  area. This back seat testing is applicable for gate & globe valve. During the testing the gland bolts should be in free condition so that no external force is applied on the gasket in the gland area.
