In order to ensure that the corrosive oxygen is displaced from the system, a way to purge the air from the sprinkler lines is required. Potter’s Self-Purging valve kit ensures high purity nitrogen is equally distributed throughout the fire sprinkler system. Installation requires no electrical connections and little to no maintenance. One self-purging valve kit at the end of each riser and the Potter Nitrogen Generator will deliver 95-99% nitrogen throughout all the branch lines. The purge valve also provides a location to monitor the nitrogen purity within the system piping.
