Products Description
CA-FIRE Wafer Type Butterfly Valve
In fire suppression infrastructure, signal butterfly valves serve as critical monitoring components within automatic sprinkler networks. Their primary function is to track the operational state of the water supply line, ensuring the fire control center receives immediate feedback on whether the valve is completely open or has been partially closed.
By providing this real-time oversight, these valves act as a fail-safe. They are generally positioned along primary water mains to mitigate the risk of human error or unauthorized tampering, which could otherwise disable the sprinkler system during an emergency.
Core Technical Advantages
Continuous Status Feedback The built-in monitoring switch tracks the disc position with high precision. It alerts the command center if the valve is moved from its fully open state, preventing unauthorized shutdowns and ensuring the water supply is always ready for action.
High-Pressure Leak Prevention Engineered for superior sealing reliability, these valves maintain tight shut-off even under pressures reaching 1.6 MPa. This robust design meets the rigorous safety standards required for modern fire-fighting infrastructure.
Streamlined Industrial Profile Utilizing a wafer or lug-style configuration, the valve occupies a smaller footprint and weighs significantly less than traditional gate valves. This makes it easier for crews to transport and install in confined mechanical rooms.
Resilient Material Engineering The valve body is cast from high-strength ductile iron and finished with a protective epoxy resin layer. This combination provides a barrier against rust and mechanical wear, extending the equipment's lifespan in damp environments.
Effortless Manual Control Equipped with a precision worm gear mechanism, the valve requires very little manual force to rotate 90°. This ensures a quick, smooth response when manual intervention is necessary during maintenance or emergencies.
Applications & Working Principle
Primary Usage Scenarios
Diverse Building Safety: Essential for automatic fire suppression networks across industrial facilities, commercial complexes, and high-rise residential properties.
Pipeline Status Tracking: Deployed in water distribution and supply lines where immediate digital feedback on valve positioning is required.
Risk Mitigation: Specifically utilized in systems that demand rigorous supervisory oversight to eliminate the risk of accidental water shut-off.
Network Segmentation: Installed on both primary mains and branch lines within a firefighting water grid to provide localized control and monitoring.
Operational Mechanism
The valve functions via a quarter-turn (90°) rotational disc that dictates the flow of water. In its "Active" state, the disc sits parallel to the pipe, ensuring a clear path for water delivery. To isolate the system, the disc is turned perpendicular to the flow, creating a secure seal.
The core of its "Signal" capability lies in an integrated position-sensing module. This electronic switch constantly tracks the disc's angle. Should the valve be tampered with or moved away from its "Full Open" position, the module triggers an immediate alert to the Fire Alarm Control Panel (FACP). This automated reporting ensures that the suppression system never remains inoperable without the facility manager's knowledge.
FAQ
1. What is the function of a signal butterfly valve in fire protection systems?
It is used to control the fire water supply and monitor the valve position, ensuring the system remains fully open and ready for operation.
2. How does the supervisory switch work?
The built-in supervisory switch sends a signal when the valve is not in the fully open position, allowing the control panel to detect abnormal valve status.
3. Where is this valve typically installed?
It is commonly installed on main or sectional fire water pipelines, such as risers or zone control points.
4. What type of operation does the valve use?
The valve is operated by a worm gear mechanism, providing smooth 90-degree rotation with low operating torque.
5. Is the valve suitable for continuous service in fire water systems?
Yes, it is designed for long-term use in fire water supply systems under normal operating conditions.
