Diaphragm seal with flange connection ST series

for pressure gaugesprocess

M&G ST Series diaphragm seals are specifically designed to protect electronic transmitters, transducers, and low pressure gauges against process 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. Type ST metal 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. Idéal for protecting instrumentation from process media -Electronic transmitters -SMART transmitters -Transducers -Low pressure gauges Idéal for process control and pipelines Materials available for corrosive applications Optional seal ratings to 3000 psig (207 bar) Threaded Seal Eléments 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 Eléments The SCT seal element can be supplied with standard ANSI Class ratings of 150, 300, and 600. The SDT sériés is similar to the SCT sériés except it is supplied with a 1/4” flushing connection.
