Threaded Diaphragm Seal Model 350V
The Model 350V threaded diaphragm seal is available in 316 SS and nitrile O-ring. PTFE or Viton available on request.
The 350 is suitable for use at 160 °C and 250 °C when a high temperature filling fluid is used. The instrument connection is ¼ " NPT.
See the pdf specification sheet for pressure limitations and options available including Teflon coating for highly corrosive process mediums.
Chemical diaphragm seals separate your process fluid from the mechanism of an attached sensing instrument.
The most common applications for using a 350 screwed type diaphragm seal are when the process fluid hardens on cooling, is viscous, very hot, highly corrosive or is unsanitary.
Teltherm offers diaphragm filling on a wide range of gauges and transducers. Please note in order to get the best out of your instrument, it may need to be evacuated overnight. Any entrapped air in the filling fluid will compromise the behaviour of your system.
