Application

This component serves as a closed-type sprinkler head for a water supply-connected sprinkler system. It uses a glass valve with an expandable liquid sealed inside the heat-sensing part. When it detects the heat of a fire, the liquid inside the glass valve expands, and when it reaches the temperature, the glass valve breaks, and water spraying starts quickly.
