Type 29 High Volumetric Displacement Welded Diaphragm Seal

  • An off-line seal with a threaded connection and all welded, all metallic housing design that does not utilize an o-ring or gasket
  • Designed with a larger diameter diaphragm for higher displacement capability
  • Maximum pressure rating is 2,500 psi
  • Displacement is limited to 0.035 cubic inches, requiring the use of gauges with 4-1/2 inch or smaller dial size and bourdon tube range no lower than 0 to 30 psi
  • A variety of upper and lower housing and diaphragm materials are available 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
