Our cast iron swing check valves feature a swing type clapper designed for use in fire sprinkler or other types of water piping systems that incorporate grooved connecting pipe ends. They are effectively used when it is necessary to permit water flow in one direction only, preventing flow in the reverse direction.
As an alternative to using an alarm check valve with a wet sprinkler system, a swing check valve may be used in a "Shotgun" arrangement whereby the valve is trimmed in a similar manner but utilizes an electric water flow switch and alarm bell instead of a water motor gong for fire notification.
