Type 25 Welded, Standard Pressure Diaphragm Seals
Type 25 Welded, Standard Pressure Diaphragm Seals
Key Features
- Designed to isolate the pressure measuring instrument from corrosive or viscous
process media - Utilize an all welded, all metallic housing design to eliminate potential leak paths
- For use with gauges with dial sizes of 2-1/2" and smaller, and pressure ranges no
less than 100 psig - Housing and diaphragm offered in a variety of materials to suit most applications
- A flushing port is available to clean wetted areas and prevent process media build up
- Consider gauge size, pressure range, media composition, ambient and operating
temperature, and maximum working pressure when selecting - For process temperatures over 212 °F a capillary or cooling element is recommended,
contact factory to order - Fill fluid must be compatible with process media; i.e. glycerine may become volatile
in conjunction with a strong oxidizing agent such as chlorine, forms of oxygen or peroxide
and nitric acids
