against process
Type SBT
media damage in a wide
range of process control
and pipeline applications. Designed for transmitter
applications where closed systems require low
sensitivity, the ST series offer superior accuracy
where greater volumetric displacements are
required.
t Type ST seals feature a continuous duty design
that permits instrument removal or replacement
while a system is in operation without causing
leakage of the process media. These seals include
a metal diaphragm which is permanently welded
to the seal’s instrument flange. The instrument or
top flange and process or bottom flange are sealed
with a non-asbestos aramid fiber gasket. Optional
glass filled TEFLON® and TEFLON-coated stainless
steel gaskets are also available.

SEAL CONFIGURATIONS
Threaded Seal Elements
The SBT seal element can be used for pressure and vacuum
applications and has a standard pressure rating of 1500 psig at
100°F (103 bar at 38°C) with an optional rating for up to 3000
psig (207 bar). The SGT seal element is similar to the SBT seal,
except that it has a 1/4 NPT flushing connection.

Flanged Seal Elements
The SCT seal element can be supplied with standard ANSI
Class ratings of 150, 300, and 600. The SDT series is similar
to the SCT series except it is supplied with a 1/4” flushing
connection.
