Accommodates Loss of Barrier Gas for Greater Sealing Reliability ​Chesterton has developed technology that makes the use of a gas seal easy and intuitive. The 4400 delivers higher reliability with lower gas consumption than conventional gas-lubricated seals. Transitions to a traditional liquid seal in the event of the loss of barrier gas and recovers to a gas seal upon restoring the barrier gas Compact flush mount design that does not require modification of the stuffing box; fits more equipment types than conventional gas seals Innovative in-Gland Control System (IGCS) dynamically controls gas pressure to process pressure​ Features Zero fugitive emission, monitoring exempt, dual gas seal design Full sealing recovering following loss of barrier gas Unique design minimizes profiled gas face wear due to loss of barrier fluid Seal transitions to a contacting wet mode during gas disruptions for greater sealing reliability In-Gland Control System (IGCS) dynamically tracks process pressure to minimize gas consumption No heat generation Designed for ANSI/API pumps, compressors, and blowers
