Fire Grooved Butterfly Valve

The Fire Grooved Butterfly Valve is a professional fire-fighting dedicated control valve specially developed for building fire protection pipeline systems, sprinkler systems and fire hydrant pipe networks. Adopting advanced grooved quick-connection structure and optimized butterfly sealing technology, this valve is designed to meet national and international fire safety standards, providing stable cut-off, flow control and reliable long-term sealing performance for fire water pipelines. Compared with traditional flanged fire valves, the grooved type features simpler installation, higher structural stability and lower on-site construction difficulty, making it the mainstream preferred valve for modern fire engineering, high-rise buildings, commercial plazas and municipal fire supporting projects.

The entire valve body is made of high-strength ductile iron material with excellent mechanical toughness and pressure resistance. The surface is treated with electrostatic epoxy resin powder coating, which forms a dense protective layer that is waterproof, rust-proof, corrosion-resistant and aging-resistant. It can adapt to long-term hidden installation in ceiling pipe trenches, damp pipe wells and outdoor open-air pipeline environments without paint peeling, rusting or structural deformation. The valve disc adopts precision-cast stainless steel material with smooth mirror polishing treatment, which effectively prevents scale adhesion, water stain accumulation and medium erosion, ensuring unobstructed fluid flow and stable long-term operation of the fire pipeline system.

The valve core sealing system adopts high-quality fire-grade EPDM rubber liner, which has excellent elasticity, compression resistance and water hammer resistance. It realizes bidirectional zero-leakage sealing under rated working pressure, completely solving the hidden danger of slow leakage of traditional fire valves under long-term static water pressure. The rubber material maintains stable physical performance in low-temperature and normal-temperature water environments, avoiding hardening, cracking and aging failure caused by long-term static pressure soaking, fully meeting the 24-hour standby operation requirements of fire protection pipelines.

Equipped with a high-precision worm gear transmission operator, the fire grooved butterfly valve achieves labor-saving, stable and accurate opening and closing operation. The deceleration structure greatly reduces operating torque, allowing easy manual switching even for large-diameter valves. It is equipped with a clear opening degree dial and reliable mechanical self-locking function, which can accurately fix the valve opening position and effectively prevent disc displacement caused by pipeline vibration, water hammer impact and medium pressure fluctuation. The intuitive on-site scale display facilitates daily inspection, pipeline debugging and regular fire safety checks.

The standardized grooved connection design is the biggest advantage of this fire valve. It requires no welding, no flange alignment and no complex auxiliary tools during installation. The valve can be quickly clamped and fixed with grooved pipe fittings, which greatly shortens the construction cycle, reduces engineering costs and improves pipeline installation accuracy. Meanwhile, the split quick-install structure facilitates later pipeline maintenance, valve replacement and system renovation without cutting or damaging the original pipeline, greatly improving the convenience of fire system daily maintenance.

With standard pressure grades of PN10 and PN16 and a complete diameter range covering DN50 to DN300, this fire grooved butterfly valve has passed professional fire safety certification. It is widely applicable in automatic sprinkler systems, fire hydrant main pipelines, building fire water supply systems, industrial plant fire pipelines and municipal fire supporting pipe networks. As a core safety component of fire protection systems, it ensures the tightness, stability and emergency response reliability of fire water pipelines.

In summary, the Fire Grooved Butterfly Valve integrates anti-corrosion durable structure, zero-leakage fire-grade sealing, labor-saving worm gear operation and efficient grooved installation advantages. With stable performance, long service life and high construction practicability, it provides solid and reliable fluid control safety guarantee for all kinds of modern fire protection engineering projects.
