In fire protection water supply systems, every valve bears the mission of “combining peacetime and wartime functions”—it must remain leak-free for extended periods and reliably open and close instantly in the event of a fire. Baian Flanged Turbine Hard-Seal Butterfly Valves are specifically designed for fire protection and high-pressure conditions. With their superior high-temperature resistance, bidirectional zero-leakage sealing, and easy and stable turbine operation, they are the ideal choice for sprinkler systems, fire hydrant systems, and fire pump room outlet pipelines.
- Hard-Seal Structure, Enhanced High-Temperature Resistance and Safety
Unlike ordinary soft-seal butterfly valves, Baian hard-seal butterfly valves utilize a stainless steel valve plate and a multi-layer metal composite sealing pair. The valve seat is overlaid with a corrosion-resistant alloy and precision-ground to form a “metal-to-metal” hard contact. This structure ensures a tight shut-off even under high temperature, high pressure, and particulate media conditions, fully meeting the requirements of fire protection systems for continuous valve effectiveness under extreme fire conditions. Even after long-term inactivity, there will be no leakage risks due to rubber aging, truly achieving “always ready, instantly usable.”
- Flange Connection for Enhanced Stability in High-Pressure Conditions
The valve body is constructed from high-strength ductile iron/cast steel, and the flange connection complies with national and fire protection industry standards. Compared to wafer-type butterfly valves, the flange structure provides stronger tensile strength and seismic resistance in high-pressure areas such as fire pump outlets, ensuring the pipeline system remains robust and leak-free under water hammer impact during pump startup.
- Turbine Drive for Precise Self-Locking Operation
Equipped with a high-precision worm gear actuator, the handwheel operation is easy and effortless, and it features a reliable self-locking function—the valve can be stably locked at any opening degree without the need for additional braking devices. Whether for manual opening and closing tests during routine inspections or rapid shut-off in emergency situations, precise control is achieved, effectively ensuring the emergency response capability of the fire protection system.
- Rigorous Testing and Fire Protection Certification
The Bai’an hard-seal butterfly valve strictly adheres to fire protection product standards such as GB 5135.6-2018 “Automatic Sprinkler Systems Part 6: General Valves,” passing numerous rigorous tests including shell strength, sealing performance, and continuous opening and closing life. Our products are widely used in fire protection projects for commercial complexes, industrial plants, high-rise buildings, and petrochemical plants, providing users with a solid fire safety barrier through stable and reliable quality.
