Diaphragm Breather Valve for Difficult Applications

PROTEGO® Diaphragm Valves function as pressure vacuum relief valves. The flexible diaphragm allows them to work as a dynamic flame arrester which provides endurance burning protection. For additional safety, these devices are equipped with a static flame arrester unit.

For extreme cold weather conditions
A specially designed valve seat, combined with the flexible diaphragm, prevents the diaphragm from freezing on the valve seat.

For problematic products
The only vent which works reliably with problem products such as Styrene or Acrylates.
