Products Description
Fire Deluge Valve For Fire Fighting
The Fire Deluge Valve For Fire Fighting is the core linkage control unit for large-flow fire suppression systems in high-risk areas, compatible with deluge water spray and foam-water combined fire suppression systems. It features "multi-material adaptability + intelligent response" and offers dual main body options: QT450-10 ductile iron and 304 stainless steel. With a rated working pressure of 1.6MPa, it supports three startup modes (automatic via pressure switch/fire detector linkage, manual, and electric) and achieves a response time ≤5s.
Structural & Material Advantages
◆Dual-Material Body Adaptability
QT450-10 Ductile Iron Body: Tensile strength ≥450MPa, elongation after fracture ≥10%, low-temperature impact toughness ≥12J/cm² at -25℃. Its surface is treated with "zinc-aluminum pseudo-alloy primer + fluorocarbon topcoat," achieving salt spray resistance ≥1000h-ideal for low-temperature industrial scenarios in northern regions.
304 Stainless Steel Body: Composed of Cr18-Ni8 alloy, it has excellent chloride corrosion resistance and salt spray resistance ≥1500h, suitable for high-corrosion environments like coastal oil depots and chemical chlor-alkali workshops.
◆Dual-Cavity Sealed Valve Disc Design
Adopting a fluororubber dual-cavity sealed valve disc, its sealing reliability is 60% higher than traditional single-cavity structures. It shows no leakage for 24h under 1.6MPa working pressure; the 0.8mm wear-resistant layer on the valve disc extends its service life to over 8 years.
◆Intelligent Linkage Module
Integrated with pressure switch and fire detector linkage interfaces, it synchronously completes "valve opening + fire pump activation + central control signal upload" once triggered-with a response time ≤5s, suitable for fast-spreading scenarios like new energy battery fires.
◆Maintenance-Friendly Structure
Equipped with a one-click reset valve and residual liquid automatic drainage system, valve disc reset and internal cleaning can be completed without disassembling pipelines during maintenance, significantly reducing maintenance time.
Application and Installation
Typical Application Scenarios
New Energy Battery Warehouses: ZSFM-X 150-1.6 (304 stainless steel) adapts to foam-water combined systems to suppress battery thermal runaway;
Oil Depot Loading Piers: ZSFM-X 200-1.6 (ductile iron) provides large-flow foam coverage to prevent fuel leakage fires;
High-Risk Theater Stages: ZSFM-X 100-1.6(G) adapts to deluge water spray systems to quickly control stage curtain fires;
Coastal Chemical Workshops: ZSFM-X 80-1.6 (304 stainless steel) resists sea breeze salt spray corrosion for long-term stable operation.
Installation & Maintenance Guidelines
5.1 Installation Key Points
Select materials based on on-site corrosion grade: 304 stainless steel (with PTFE gaskets) for high-corrosion areas, ductile iron (with oil-resistant rubber gaskets) for conventional areas;
Reserve a straight pipe section ≥4× the pipe diameter on the water inlet side to avoid turbulence affecting response speed; leave ≥500mm operating space above the valve unit;
After installation, conduct a 30-minute pressure holding test at 1.92MPa (1.2× rated pressure), and verify the response time of all three startup modes simultaneously.
5.2 Maintenance Strategy
Monthly: Inspect the wiring stability of the intelligent module, and manually trigger the alarm bell to verify functionality;
Quarterly: Activate the residual liquid drainage system, test valve disc sealing, and perform foam concentrate compatibility tests;
Annually: Disassemble the valve disc to check the wear-resistant layer thickness, and entrust a third party to re-calibrate pressure/strength test parameters;
Low-Temperature Season (≤-10℃): Wrap ductile iron valve units with silicone rubber insulation sleeves to prevent residual liquid from freezing and expanding.

FAQ
Q1: What is a Deluge Alarm Valve?
A1: A deluge alarm valve is a control device used in fire protection systems to rapidly release large volumes of water or foam when a fire is detected. It remains closed under normal conditions and opens automatically once the detection system is triggered.
Q2: How does the deluge valve system work?
A2: When the detection system senses heat or smoke, it activates the deluge valve. Water then flows through open-type sprinklers or spray nozzles, quickly flooding the protected area to control or extinguish the fire.
Q3: What is the difference between a deluge valve and a wet alarm valve?
A3: A wet alarm valve holds water under pressure in the piping at all times, while a deluge valve keeps the piping dry until activation. The deluge type is designed for high-risk areas requiring fast, full-area discharge.
Q4: Where is the deluge alarm valve commonly used?
A4: It is widely applied in power plants, transformer rooms, aircraft hangars, oil & gas facilities, chemical plants, and other high-hazard industrial zones.
Q5: What materials are CA-FIRE deluge valves made of?
A5: CA-FIRE deluge alarm valves are constructed from durable cast or ductile iron with corrosion-resistant coatings to ensure strength and reliability under harsh operating conditions.
