Mô tả
The DIF-S diaphragm seal features a flanged connection with a screwed diaphragm, designed for pairing with pressure gauges or transmitters. It is suitable for harsh applications involving high temperature, high pressure, vibration, or corrosive media. The system tolerates extreme process temperatures up to +300°C and can be built from multiple material options—such as 316L, Hastelloy C276, Tantalum, and Titanium—making it ideal for chemical, petrochemical, process engineering, and cement industries. Its double-flange construction increases diaphragm size for improved measurement accuracy and compatibility with various piping standards.
