Leak-Tightness at Line Stream, Shaft
Passages and Atmosphere
A perfect zero leakage seal at bi-direction is obtained
by the compression of the inner between the valve
body and the edge of the disc. A perfect zero leakage
seal is provided by means of flatted liner around both
up and down shaft passages and the spherically ma-
chined disc. Since the seat stem hole is smaller than
the stem diameter, there is a compression fit forming a
secondary seal. The seal insures that no fluid will leak
to atmosphere.
