Type 10/10H, Replaceable, Standard & Elevated Pressure, Bolted Diaphragm Seals

Key Features

  • Designed to isolate the pressure measuring instrument from high  temperatures, or corrosive or viscous process media
  • 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" NPT through 1-1/2" 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
