How it works:

The seal automatically deflates during opening and closing, thereby avoiding contact with the dome and eliminating unnecessary wear. The seal automatically inflates only when the dome is fully closed.

Customized options:

• Several inflatable seals are available, depending upon the application. The choice includes a white food quality seal as well as those specially formulated for high temperature or other hostile applications.
• Totally unrestricted full bore material flow is assured through the unique design of the ‘dome’ assembly. Different raw materials can be specified for the dome and a choice of
  surface coatings is also available.
• Water cooling is recommended for applications involving temperatures in excess of 400°F. Water cooled Valves are available in three options in selective sizes throughout the range.

To date, more than 10,000 Spheri Valves have been sold world-wide, for applications across a range of industries including:- minerals, power, iron, steel, food, pharmaceuticals, chemicals, and plastics.
