Signal-type Fire Protection Butterfly Valve
The Corrosion-Resistant Fire Protection Butterfly Valve is a specialized solution engineered for firefighting systems exposed to harsh conditions, such as coastal areas, industrial chemical plants, and subterranean municipal networks. While standard valves may fail due to oxidation, this series utilizes premium metallurgy and advanced polymer coatings to ensure the valve remains operational after years of dormancy. It serves as a critical isolation point for sprinkler systems, ensuring immediate water delivery during an emergency.

Product Feature and Application
Wide Product Range
Enhanced Corrosion Barrier: The body is treated with a high-build Fusion Bonded Epoxy (FBE) coating that is resistant to salt spray, soil acids, and high humidity.
Low Friction Operation: High-performance stem bushings and precision-ground discs ensure low torque requirements, preventing the valve from "seizing" in the closed position.
Wide Applications
We offer a variety of transmission components, including sprockets, roller chains, gears, couplings, racks, hubs, pulleys, taper sleeves, bearing seats, and more.
High Strength
Bi-directional Bubble-Tight Seal: The resilient seat design provides 100% leak-proof performance in both flow directions.
Applications: Specifically designed for offshore platforms, desalination plants, chemical processing facilities, seaside municipal projects, and underground fire mains.
Professional
We offer a variety of transmission components, including sprockets, roller chains, gears, couplings, racks, hubs, pulleys, taper sleeves, bearing seats, and more.
Product Details
- Anti-Corrosive Stem: The stem is manufactured from high-strength stainless steel with a polished finish to reduce wear on the seals and prevent galvanic corrosion.
- Encapsulated Disc: The disc core is entirely encapsulated in high-grade EPDM, eliminating metal-to-liquid contact and preventing internal rust build-up.
- Weatherproof Actuator: For lever or gear-operated models, the external hardware (bolts, nuts, and plates) is made from SS304 or galvanized steel to withstand outdoor exposure.
- Secondary Seal System: Features a triple O-ring arrangement at the stem entry to prevent external contaminants from entering the valve internals.

Transport Package
- Individual Shielding: Each valve is vacuum-sealed or wrapped in anti-corrosion VCI (Volatile Corrosion Inhibitor) film.
- Standard Crating: Packed in heavy-duty, heat-treated wooden crates (ISPM-15 compliant) with internal bracing to prevent movement.
- Labeling: Clear marking of maritime symbols, pressure ratings, and material certifications for easy customs clearance and site identification.
After-sales Service
Extended Warranty: 24-month quality guarantee reflecting the product's superior corrosion resistance.
On-site Inspection Support: Expert guidance for installation in "high-corrosion zones" to ensure proper grounding and cathodic protection integration if required.
Rapid Response Spares: 48-hour dispatch for seal kits and replacement components to minimize system downtime during maintenance.
