Product Description

Flanged seals with extended diaphragms isolate pressure gauges from the medium, preventing damage from corrosive, viscous, or toxic media.

The extended diaphragm seal design makes it suitable for thick-walled vessels, insulated pipes, or containers, effectively avoiding measurement interference caused by insulation or vessel wall thickness.

Features

• Extended diaphragms can be customized to requirements (diameter, length, material)
• Suitable for thick-walled or isolated tanks and pipes
• Flanges according to ASME/ANSI B 16.5, DIN EN 1092-1, or other standards
• Flange and diaphragm materials are available on request

Applications

Flanged diaphragm seals with extended diaphragms are suitable for high-viscosity, easy-to-crystallize, corrosive, and high-temperature media, and can be used for pressure measurement in thick-walled containers, pipelines, and other processes.
