Description

ABSTRACT:
A valve body includes: a main body having a recess formed in a surface thereof facing a valve seat. A sealing member fills the recess of the main body. The sealing member is made of annealed nickel. The annealed nickel has a low hardness, so that the sealing member is slightly depressed by abutment thereof against the valve seat. The sealing member is then hardened by further application of stresses. Therefore, complete sealing between the sealing member and the valve seat can be achieved.
