MJC 20mm - heat activated, Single Outlet

GW Multiple Jet Controls (MJC’s) are for use in sprinkler or waterspray systems where it is required to operate small groups of open sprinklers or waterspray nozzles simultaneously.

Each MJC contains a fragible glass bulb sensitive to heat. The bulb is pre-loaded at the factory to hold a Nickel/Silver plate against a brass seal which provides a water and air tight seal. The application of heat bursts the bulb releasing the disc and allowing water to flow.
