Description
The Reliable Model B1 Accelerator with integral Accelo-Check (anti-flooding device) is used to speed the operation of both dry pipe valves (in dry-type automatic sprinkler systems) and deluge valves (in preaction sprinkler systems). Both of these systems utilize pressurized air or nitrogen in the piping, instead of water, to prevent freezing or to prevent the accidental release of water.
The accelerated operation of the dry pipe valve permits an increase in both the number of sprinklers that can be controlled by one dry pipe valve and the volume of the dry system that can be installed.
