Products Description
CA-FIRE Grooved Deluge Fire Alarm Valve
This Fire Deluge Alarm Valve features precise structural design and reliable performance parameters:
Design & Connection Standards: Complies with GB 5135.5 for design and manufacturing, and GB/T 1724.6 for flange connection, ensuring installation compatibility and industry compliance.
Pressure Performance: With a nominal working pressure of 1.6MPa and a sealing test pressure of 3.2MPa, it meets pressure requirements for regular fire-extinguishing scenarios and has high-pressure sealing redundancy.
Dimension Specifications: Available in multiple models from DN50 to DN300, as well as 100(G), 150(G), and 200(G). Each model corresponds to different structural dimensions (such as h, H, A, B, M, N, D1, n-D, C, etc. – refer to the specification table), suitable for system design requirements of different pipe diameters and installation spaces.
| Model | Nominal Diameter (DN) | Height (mm) | Working Pressure | Seal Test | Strength Test | Hydraulic Loss |
|---|---|---|---|---|---|---|
| ZSFM 50-350 | DN50 / DN65 / DN80 / DN100 / DN125 / DN150 / DN200 / DN250 / DN300 / DN350 | 270 / 270 / 330 / 340 / 415 / 415 / 530 / 650 / 770 / 850 | 1.6 MPa | 3.2 MPa | 6.4 MPa | <0.08 MPa |
| Grooved ZSFM 80-200 (G) | DN80 / DN100 / DN150 / DN200 | 330 / 360 / 425 / 530 | 1.6 MPa | 3.2 MPa | 6.4 MPa | <0.08 MPa |
Key Features & Advantages
Installation Compliance: Install strictly in accordance with GB 5135.5 and local fire codes. Ensure flange connections are leak-proof; a 3.2MPa sealing pressure test must be conducted after installation.
Regular Inspection: Inspect valve disc tightness and control device sensitivity quarterly; conduct full-system pressure tests and functional tests annually to ensure reliable activation in emergencies.
Operational Safety: Non-professionals are prohibited from disassembling or adjusting valve components; clear personnel and important equipment around during activation tests to avoid water spray impact.
Identification Management: Set clear "Fire Deluge Alarm Valve" labels at valves and control devices, indicating operation procedures, emergency phone numbers, and maintenance cycles.
Ultra-Fast Response: The valve disc opens quickly, enabling large-area water spraying in a short time to effectively contain fire spread and reduce fire losses.
High Compliance: Fully complies with national standards such as GB 5135.5 and GB/T 1724.6, and has obtained authoritative fire certifications to ensure smooth project acceptance.
Multi-Model Adaptation: Covers models from DN50 to DN300 and special "(G)" models, suitable for different pipe diameters, installation spaces, and flow requirements, with strong scene compatibility.
Reliable Sealing: Designed with a 3.2MPa sealing test pressure, it has no leakage risk during long-term use, ensuring stable pressure and efficient water spraying during fire extinguishing.
Applications & Working Principle
The Fire Deluge Alarm Valve is suitable for scenarios where fire spreads rapidly and large-area rapid fire control is required. Typical applications include:
Industrial Fields: Petrochemical plants, oil depots, painting workshops, cable ducts, large equipment rooms, and other flammable areas where fires spread easily.
Civil & Public Buildings: Large stadiums, exhibition centers, warehousing and logistics centers, data centers, high-end commercial complexes, and other large-space venues.
Special High-Risk Sites: Power distribution rooms, generator rooms, boiler rooms, and other areas with high incidence of electrical/thermal fires.
Working Principle
The Fire Deluge Alarm Valve realizes the linked workflow of "activation - water spraying - alarm" through linkage control devices (electric, pneumatic, hydraulic, or automatic fire alarm systems):
Activation Phase: When a fire detector (or manual activation device) sends a signal, the control mechanism acts, and the deluge valve disc opens rapidly.
Water Spraying & Alarm Phase: After the valve disc opens, water is sprayed through open sprinklers for large-area fire extinguishing; meanwhile, the water flow drives alarm devices such as water motors and pressure switches to issue audible and visual alarms, achieving synchronous linkage of fire extinguishing and alarming.
Reset Phase: After the fire is extinguished, the valve disc is closed through manual or automatic control devices, and the system resets to standby status.
Safety & Environmental Responsibility
Enhanced Safety – Designed to ensure leak-free operation under working pressures up to 1.6 MPa. Grooved connections minimize joint failures and maintain system integrity during emergencies.
Reliable Fire Protection – Fast and secure grooved installation ensures the valve functions properly when activated, protecting lives and property.
Environmental Consideration – Grooved connections reduce the need for welding, flanges, and excessive fittings, lowering material waste and energy consumption during installation.
Sustainable Maintenance – Easy disassembly and reassembly allow for inspections and repairs without cutting or discarding pipe sections, reducing environmental impact.
