ZSFZ150 Ductile Iron Wet Alarm Valve with Flange Ends 8-20 Bar Working Pressure Check Valves for Fir

Spark ZSFY Pre-Action Alarm Valve Assembly Launches | A Dual-Advantage Solution of "Dry Protection + Rapid Suppression" for Water-Sensitive Locations

Fire protection brand Spark has released the ZSFY pre-action alarm valve assembly, centered on "dry pipeline network + dual-mode response" to become a dedicated control device for fire systems in high-sensitivity scenarios.

This valve assembly uses flange connections to adapt to mainstream pipelines, made of cast iron with anti-corrosion material, and has a rated working pressure of 1.6MPa—stably applicable to water-sensitive environments like archives and precision workshops. It maintains a dry pipeline network in normal conditions, completely avoiding the accidental discharge risk of traditional wet systems; during fires, it supports electric and manual dual-mode activation: the electric mode links to the fire control panel with a water filling response time of ≤60s, quickly starting sprinkler suppression; the manual mode serves as an emergency backup to ensure reliable activation in extreme working conditions.

The product supports operation in a -10℃~50℃ wide temperature range, is CE and ISO certified, and meets international fire safety standards. Its built-in pressure monitoring and signal feedback module can synchronize system status to the fire control center in real time, reducing operation and maintenance management costs. The valve assembly is now available on Spark’s self-built site, with bulk purchasing and scenario-based parameter customization inquiries supported.
