ZSFY Preaction Fire Alarm Valve Group DN80-DN250
The Pre-Action Alarm Valve serves as an essential control unit within advanced fire protection systems. Engineered for environments where accidental water discharge poses a significant risk, this system maintains a dry pipe network under supervisory air pressure. It requires a dual-confirmation sequence—from an independent detection system and the sprinkler heads themselves—before releasing water, thereby offering superior protection against unwarranted water damage.

Core Technical Innovation: Dual-system Integrated Design
CA-FIRE Pre-Action Valve Assembly
Different from traditional wet alarm valve and dry deluge valve with inherent defects, our upgraded preaction alarm valve adopts an innovative integrated linkage structure of fire detection and sprinkler fire extinguishing. It combines the advantages of wet fire sprinkler system and dry fire protection system perfectly.
The pipeline remains dry and water-free under normal working condition, which avoids pipe freezing crack, pipeline corrosion and accidental water leakage effectively. The valve will only open for pipeline water filling after receiving confirmed dual fire alarm signals, realizing fast fire suppression while eliminating false spray risks fundamentally.
Safety Innovation: Dual Interlock Anti-false Spray Technology
Equipped with optimized dual interlock control system as upgraded innovation, this preaction valve realizes double signal confirmation activation. The valve cannot open and discharge water via single misoperation, sensor failure, pipeline pressure fluctuation or artificial mistaken touch.
Compared with ordinary single-interlock preaction valves on the market, it upgrades site safety protection level, prevents huge property loss caused by wrong water spraying, which is the core optimized design for water-sensitive high-value scenarios.
Structural Innovation: Modular Integrated Valve Body Structure
1. Premium integrated ductile iron casting body, high pressure resistance, anti-corrosion and long service life, customized for PN1.6MPa standard fire pipeline working pressure;
2. Full-size standardized modular design: Complete DN80/DN100/DN125/DN150/DN200/DN250 specifications available, unified standard flange interface, compatible with global mainstream fire pipe installation standards;
3. Dual control startup mode: Automatic linkage startup with fire alarm system + local manual emergency startup, double guarantee for emergency fire response, avoiding startup failure risk.
Electric Control Innovation: Integrated Explosion-proof Matching Control Panel
Breaking the disadvantage of scattered matched accessories of ordinary valves, this valve set is equipped with factory integrated explosion-proof control cabinet. With certified explosion-proof grade Ex db IIB T6 Gb, it can be applied in flammable, explosive chemical workshops and dust hazardous sites directly.
Plug-and-play electric structure, seamless connection with international fire alarm host, simplifies on-site wiring, installation and debugging work, saves extra matching procurement cost for engineering buyers.
Engineering & Cost Innovation: Low Maintenance & High Cost-performance
1. Low daily maintenance cost: Dry pipeline design cuts regular drainage, anti-rust and heat preservation maintenance work by more than 60%;
2. Simplify engineering design: One valve replaces the combined assembly of dry valve + anti-leakage accessory, shortens construction cycle;
3. Complete qualification support: Own global recognized fire certification and test reports, fully compliant with international fire engineering bidding and acceptance standards;
4. Support OEM customized service: Custom logo, packing and parameter adjustment to meet regional fire code requirements.
