Product details
ZSFWY temperature-sensitive rain-shower valve, as a small-caliber rain-shower valve, is mainly used for fire separation by doors, windows,etc. It can also be used for directional fire separation among the equipments and in the areas.
The valve adopts diaphragm structure. The valve is divided into a working chamber and a control chamber by the diaphragm. When water flow acts on the working chamber, the pressure water entering the control chamber from the diversion hole acts on the diaphragm (which is also connected with the sprinkler). The sealing performance of the valve disc is guaranteed due to the difference of the water-receiving area between the upper and lower diaphragms.
