Diaphragm seal for pressure gauges
NOSHOK
Maximum pressure rating is 2,000 psi
Utilizes a replaceable diaphragm clamped between the flanged metal housings with an o-ring seal to create a leak-free union
Process connection sizes from 1/4 inch NPT through 1-1/2 inch NPT
Flushing port connection is an available option that allows the wetted areas of the seal to be cleaned, or the process vented without removing the unit from the line
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
