ZSFM type rain shower valve adopts the principle of diaphragm check. When the pipeline pressure on the two sides of the diaphragm is basically balanced, the diaphragm is closed. When the pressure of the water supply system is greater than the pressure of the pipeline sprinkler system, the diaphragm can automatically open. A one-way check valve can be combined with other components to form a variety of rain alarm fire extinguishing systems, suitable for hospitals, hotels, shopping malls, factories, airports, casinos, libraries, stadiums, convention centers and other automatic sprinkler systems.
