Top Chamber Diaphragm Seals

Top Chamber Diaphragm Seals are specialized pressure isolation devices designed for applications involving viscous, slurry, or solid-laden process media. In this design, the diaphragm is positioned at the top of the chamber, allowing process fluid to act directly on the diaphragm while minimizing sediment accumulation. This configuration helps prevent clogging, ensures accurate pressure transmission, and improves reliability in challenging process conditions.

Manufactured from high-quality materials such as SS 316, SS 316L, Hastelloy, Monel, or PTFE-lined constructions, Top Chamber Diaphragm Seals provide excellent corrosion resistance and durability. They are commonly used with pressure gauges, transmitters, and switches, and can be mounted directly or via capillary for remote installation. These seals are ideal for industries where process cleanliness, clog prevention, and measurement accuracy are critical.
