MGS9/7 Continuous Duty Diaphragm Seal, Welded, with Flanged Connection
Brand: Nuova FimaDiaphragm seals are designed to isolate the sensing element of pressure gauges, pressure switches and electronic pressure transmitter from process fluids which may be corrosive, viscous, sedimentous and/or with a high temperature.
“Continuous duty” version as per ASME B40.2 : in case of accidental removal of the instrument or of liquid filling leak the diaphragm will place on the upper cup preventing any damage and any process liquid leak.
Thanks to an exclusive calibration system the pressure gauge should stand an overpressure of 210 bar without the help of any pressure control switch.
Process side are ASME/EN 1092 flanged to suit application in chemical, petrochemical, water treatment and paper industries.
