  • The diaphragm is Teflon coated to provide an integral gasket, thus assuring a leak-tight connection between the diaphragm and the bottom housing.
  • Top housing and pressure instrument are removable.
  • Continuous-duty design will prevent loss of process fluid if pressure instrument is removed or fails.
