Products Description
Pre-Action Sprinkler Deluge Valve with Wet Alarm Check Stainless Steel Ductile Iron Firefighting Eme
Pre-Action Alarm Valve Assembly
This is Spark’s ZSFY100 pre-action alarm valve assembly, a core control device for dry and pre-action fire systems, widely used in water-sensitive locations such as libraries, data centers, and cold storage facilities. It integrates functions like alarm valve, pressure monitoring, and signal feedback—during a fire, it quickly fills with water and triggers an alarm, balancing the dual needs of "preventing accidental discharge" and "rapid fire suppression." Made of anti-corrosion materials with brass connectors, it is compatible with water-based fire systems and meets high industry safety standards.
