MGS9/WAF Wafer Diaphragm Seal
Brand: Nuova FimaDiaphragm seals are designed to isolate the sensing element of pressure gauges, pressure switches and electronic pressure transmitters from process liquids which may be corrosive, viscous, sedimentous and/or with a high temperature.
The diaphragm welded to the upper body and leak proof tested, ensure separation of filling fluid from process medium.
Diaphragm faced position permit an accurate and deeper cleaning.
Process sizes are ASME - EN 1092 flanged to suit application in chemical, petrochemical, water treatment, paper.
