Shuttle Check Valve


The brass shuttle valve is used to connect two cylinders to a common discharge pipe and nozzle(s). All threads are available with 1’’ or 1-1/2’’ NPT The purpose of having a reserve supply is that after the first cylinder (main) is discharged, the second cylinder (reserve) can be manually transferred via main/reserve switch to restore firefighting readiness.

The shuttle valve contains a shuttle check that closes off the piping to the first cylinder (main) when empty. When the second cylinder is discharged, the shuttle check prevents the charge of the second cylinder into the first empty cylinder (main) connected on the same manifold, thus reducing unnecessary Clean Agent loss.
