MJC Multiple Jet Controls

Available in DN20 through DN50 pipe sizes, Tyco® Series MJC multiple jet controls are control valves with self-contained heat-actuating units. Upon operation, the MJCs permit a flow of extinguishing medium (usually water) through open spray devices, such as nozzles or non-automatic (open) sprinklers. The MJCs are typically used as an auxiliary deluge valve to control the flow of water to specific as within a larger wet pipe, dry pipe, or deluge system. As such, they can be used with supply piping from either a wet pipe system or a dry pipe or deluge system. In all cases, waterflow alarms are provided by the main automatic control valve for the system that supplies the supply line to the Series MJC multiple jet controls (e.g., alarm valves, dry pipe valves, or deluge valves).
