Antistatic stem with pyramid segment as
1.st stage sealing 45 degrees slope.
O-ring as 2. stage sealing element.
Anti static devices stem-to-ball and
stem-to-body as standard.
Smooth stem finish reduces seal friction
and operating torque prolonging service
intervals.
V-ring in multiple layers expanding side-
ways and offering the 3rd sealing ele-
ment.
Gland of stainless steel equalizes the
compressive forces on the sealing sys-
tem.
Belleville washers keep the sealing sys-
tem optimal during changing pressures
and temperatures.
Lock saddle stabilizing the stem nut
avoiding loosening during operation.
Stem nut compresses the entire stem
system to make the sealing optimal.
