ZSFW Temperature-sensitive Rain Shower Valve is a small-caliber rain shower valve mainly used for fire separation in doorways, windows, and other areas. It can also be used for directional fire separation in equipment and regions.
This valve uses a diaphragm structure that divides the valve into a working chamber and a control chamber. While water flows into the working chamber, pressure water from the inlet flows into the control chamber through the diaphragm (which is in communication with the spray head). Due to the difference in water-affected area on the upper and lower side of the diaphragm, the sealing performance of the valve disc is guaranteed.
In the event of a fire, the thermal-sensitive spray head is activated, and the diaphragm in the control chamber opens to release pressure, allowing water to flow towards the open water curtain spray head to prevent the spread of fire.
