Continuous duty
I section extension to facilitate smaller flanged connection
Ideal for general purpose application
Suitable for anti corrosive protection
Available with Flushing Ring (Optional)
Applications :
Diaphragm seals are provided in the instruments like
pressure gauges, switches, transmitters in order to
isolate the sensing element from the main service
due to its corrosive, viscous and sedimented nature
