Signal Grooved Butterfly Valve

The Signal Grooved Butterfly Valve is a specialized pipeline safety control valve integrating grooved quick-install structure and mechanical signal feedback function. Developed mainly for fire protection linkage systems and intelligent water supply pipelines, this valve not only realizes reliable fluid cut-off and regulation but also feeds back real-time valve opening and closing status to the control cabinet and fire alarm system. Different from ordinary grooved butterfly valves, it features an external signal indicator and precision travel switch, allowing remote monitoring of pipeline operating conditions and greatly improving the safety and intelligence level of building piping systems. With standard grooved connection, it supports fast installation without welding or flanges, which is highly suitable for engineering construction and pipeline renovation.

The valve body is made of high-strength ductile iron with electrostatic epoxy anti-corrosion coating, effectively resisting rust, oxidation and water erosion during long-term indoor and outdoor operation. The precision-machined stainless steel butterfly disc provides smooth fluid passage and prevents scale and impurity accumulation. The high-quality EPDM sealing liner achieves bidirectional zero-leakage sealing, with excellent aging resistance, elastic recovery and pressure resistance. It maintains stable sealing performance under frequent switching and long-duration water hammer impact, fully adapting to fire water, circulating water and municipal water supply working environments.

The core advantage of this valve is its stable signal feedback function. Equipped with a high-precision mechanical signal device linked with the valve shaft, it can accurately capture the full-open and full-close positions of the valve. When the valve completes opening or closing actions, the built-in travel switch outputs passive electric signals to the fire control system or PLC control system, realizing real-time remote status judgment and linkage control. The mechanical trigger mode avoids signal delay and failure caused by electronic component aging, ensuring high accuracy and stability in long-term fire safety monitoring.

Adopting optimized worm gear manual transmission, the valve features labor-saving operation and precise angle adjustment. The dial display clearly shows the opening degree, facilitating on-site inspection and flow control. The self-locking structure effectively fixes the valve position to prevent displacement caused by pipeline vibration and medium impact. Benefiting from the grooved connection design, the valve is compact, lightweight and easy to install in narrow pipe wells, ceiling concealed pipelines and densely arranged piping areas. It simplifies construction procedures, shortens project cycles and reduces later maintenance difficulty.

Rated at PN10 and PN16 pressure levels with a complete diameter range from DN50 to DN300, the signal grooved butterfly valve is widely used in fire protection water supply main pipelines, building fire linkage systems, municipal water supply and drainage, HVAC circulating water and intelligent building pipeline projects. It complies with standard fire safety requirements and is a mandatory matching valve for fire linkage monitoring systems.

In summary, the Signal Grooved Butterfly Valve combines fast grooved installation, durable zero-leakage sealing and accurate signal feedback function. It solves the problem of invisible pipeline valve status, provides reliable data support for remote monitoring and fire linkage control, and is a high-cost-performance safety valve widely applied in modern construction and municipal fire protection engineering.
