Type 30L Reduced Pressure, Non-Metallic Lower, Bolted, Non-Replaceable Diaphragm Seals

 

 

  • Designed for applications where typical metallic lower housings cannot
    withstand process media
  • Can be used for remote mounting of pressure instrument(s) with capillary
  • Utilizes an all metallic diaphragm welded to the upper housing to allow
    replacement of the non-metallic lower housing while maintaining continuity of
    the measuring system
  • Consider instrument size, pressure range, media composition, ambient
    and operating temperature, and maximum working pressure when selecting
  • Fill fluid must be compatible with process media; i.e. Glycerin may become
    volatile in conjunction with a strong oxidizing agent such as chlorine, forms
    of oxygen or peroxide and nitric acids
