D400 Diaphragm seal with compact process flange Main Features Pressure range from 160 mbar to 160 bar Temperature -60 °C … 200 °C Class 150 to 900 NPS 1/2" to 2"1/2 PN10 to PN160 DN10 to DN65 Applications Oil & Gas / Chemical Water / Waste water Energy Process technic Technical Data This diaphragm seals with flanged process connection are used to protect pressure gauges from high temperatures, aggressive or corrosive fluids. The design of the process flange allows direct mounting on standardized flange connections of pipes or tanks. Different diaphragm materials can be selected to adapt the seal to various applications and process fluids. The diaphragm seals can be mounted to pressure gauges or pressure switches directly or with a flexible capillary. For use with electronic transmitters for pressure and differential pressure the product series D9xx is recommended, especially for low pressure ranges.
