Fire Signal Grooved Butterfly Valve

The Fire Signal Grooved Butterfly Valve is a dedicated fire-fighting safety valve designed for building fire protection linkage pipeline systems. Integrating grooved quick-install structure, worm gear manual operation and mechanical signal feedback device, this valve serves as a key monitoring and cut-off component for fire water supply pipelines. Different from ordinary butterfly valves, it features certified fire signal output function, which can accurately transmit full-open and full-close status signals to the fire alarm control cabinet, realizing real-time pipeline monitoring and automatic system linkage. Owing to its grooved connection design, the valve enables fast installation without welding or flange assembly, greatly improving construction efficiency and meeting standardized fire engineering requirements.

Manufactured from high-strength ductile iron, the valve body is treated with electrostatic epoxy coating to achieve excellent anti-corrosion, anti-rust and moisture-proof performance, adapting to long-term use in indoor pipe wells, ceiling concealed installation and outdoor fire pipeline environments. The stainless steel valve disc is precisely polished to ensure smooth fluid flow and prevent scale accumulation and medium impact damage. The high-quality EPDM rubber liner provides stable bidirectional zero-leakage sealing, featuring outstanding pressure resistance, aging resistance and water hammer resistance. It maintains reliable sealing performance under long-term static pressure and frequent emergency switching, fully complying with fire-fighting pipeline operating standards.

Equipped with a professional fire signal mechanism, the valve adopts mechanical linkage induction to ensure highly accurate status feedback. When the valve reaches full open or full closed position, the built-in travel switch automatically outputs passive switch signals to support fire system remote monitoring, fault alarm and linkage startup. The purely mechanical signal triggering structure avoids electronic failure, signal drift and delayed response, ensuring long-term stable and zero-misjudgment operation for fire safety supervision. A visible opening dial is equipped on the worm gear operator, allowing staff to check the valve state on site intuitively.

The valve adopts labor-saving worm gear transmission and reliable self-locking structure, which can stably fix the valve opening angle and effectively prevent position deviation caused by pipeline vibration, water hammer and medium pressure fluctuation. The grooved connection structure features simple assembly, firm connection and convenient later maintenance and pipeline renovation. It is lightweight and compact, perfectly suitable for dense pipeline arrangement and limited installation space in modern high-rise buildings, commercial complexes and municipal fire projects.

With standard PN10 and PN16 pressure grades and full diameter range from DN50 to DN300, this fire signal butterfly valve is specially certified for fire protection systems. It is widely used in building fire water supply pipelines, automatic fire linkage control systems, fire spray pipe networks and fire hydrant pipeline systems. It is a mandatory safety component to ensure the operability and monitorability of building fire water systems.

In conclusion, the Fire Signal Grooved Butterfly Valve integrates fast grooved installation, zero-leakage sealing and professional fire signal feedback functions. With stable performance, high monitoring accuracy and strict fire standard compliance, it provides reliable safety guarantee for modern building fire protection engineering and is the preferred supporting valve for standardized fire pipeline systems.
