Fire Gate Valve: Core Parameters & Applications
The Fire Gate Valve is a core control component in fire protection systems, designed to quickly cut off or regulate the flow of fire-fighting water (or fire-extinguishing agents) in emergency scenarios. It serves as a "safety switch" for fire-fighting pipelines, ensuring that water can be accurately delivered to fire points when a fire occurs, and preventing pipeline leakage or invalid water consumption during normal operation. Widely used in industrial plants, high-rise buildings, commercial complexes, and other places, it is an essential equipment to comply with fire safety standards and protect life and property safety.

Products Description
CA-FIRE Ductile Iron Gate Valve
The Fire Gate Valve consists of key components including a valve body, gate plate, valve stem, sealing ring, and driving device. Its body is typically made of ductile iron or carbon steel, with high corrosion resistance and pressure-bearing capacity (adaptable to working pressures of 1.0-2.5MPa, meeting the pressure requirements of most fire-fighting pipelines). The gate plate adopts a wedge-shaped or parallel structure, and the sealing ring is made of nitrile rubber or EPDM, ensuring zero leakage when the valve is closed.
In terms of driving mode, it supports manual (handwheel), electric, or pneumatic operation: manual valves are suitable for small-caliber pipelines (DN50-DN200) with convenient on-site operation; electric/pneumatic valves are applicable to large-caliber (DN250+) or hard-to-reach locations, enabling remote control to improve emergency response speed. The valve is equipped with a position indicator to clearly show the "open/close" state, and complies with international standards such as GB 5135.1 (Chinese standard) and API 600 (international standard) for stable performance in high-temperature (≤120℃) and humid environments.

Products Features
CA-FIRE Ductile Iron Gate Valve
The valve body is forged or cast with high-quality materials, resisting impact and deformation, and adapting to harsh working conditions such as pipeline vibration.
Efficient Sealing Performance
The combination of wedge gate plate and elastic sealing ring achieves tight sealing, avoiding water leakage that may affect fire-extinguishing efficiency.
It can work normally in water, foam, and other fire-extinguishing media, with a temperature range of -10℃ to 120℃, suitable for both indoor and outdoor use.
Applications of CA-FIRE Ductile Iron Gate Valve
Industrial Scenarios: Factories, chemical plants, and power stations – installed in fire-fighting pipelines of production workshops, storage tanks (such as oil tanks, chemical reagent tanks), to quickly cut off or supply fire-extinguishing agents in case of leakage or fire.
Civil Buildings: High-rise residential buildings, hotels, and shopping malls – arranged in the main pipeline of the building's fire hydrant system and automatic sprinkler system, ensuring that each floor can obtain sufficient water pressure when a fire occurs.
Public Facilities: Hospitals, schools, and subway stations – used in key areas such as operating rooms, laboratory warehouses, and subway platforms, with electric valves connected to the building's fire control center for remote emergency control.
Special Places: Oil depots, ports, and tunnel projects – adopted in large-diameter pipelines (DN300+) to cope with large-scale fire risks, with explosion-proof design for flammable and explosive environments.
FAQ– CA-FIRE Ductile Iron Gate Valve
Q: How to select the appropriate caliber of Fire Gate Valve?
A: The caliber should match the diameter of the fire-fighting pipeline (e.g., a DN100 pipeline should be equipped with a DN100 valve). At the same time, consider the maximum water flow required for fire extinguishing in the area – for large spaces (such as workshops over 1000㎡), select a larger caliber (DN150+) to ensure sufficient water supply.
Q: How often does the Fire Gate Valve need maintenance?
A: For indoor valves, conduct a visual inspection (checking the sealing state and position indicator) every 3 months, and a manual opening/closing test every 6 months; for outdoor or harsh-environment valves, shorten the maintenance cycle to 1 month (focus on anti-rust treatment of the valve stem).
Q: What should be paid attention to during the installation of the valve?
A: ① Ensure the valve is installed in the correct direction (the flow direction mark on the valve body is consistent with the pipeline water flow); ② Reserve maintenance space around the valve (at least 50cm for manual valves, and additional space for electric valve wiring); ③ After installation, conduct a pressure test (1.5 times the working pressure) to check for leakage.
