Key Features
-
Rapid Operation – The quarter-turn mechanism allows for fast opening and closing, enabling quick water supply during emergencies.
-
Compact and Lightweight – Compared to gate valves, the butterfly valve requires less installation space and is easier to handle.
-
Clear Position Indication – Many fire butterfly valves are equipped with a signal gearbox or tamper switch, allowing remote monitoring of valve status in fire alarm systems.
Materials and Construction
Typically, the valve body is made from ductile iron or carbon steel for durability. The disc may be stainless steel or ductile iron with epoxy coating, while the seat is often made of resilient materials like EPDM to ensure a tight seal. For fire service, materials are selected to withstand high pressure and ensure long service life under frequent testing and emergency use.
Applications
Fire butterfly valves are widely used in:
-
Automatic Sprinkler Systems – Regulating or isolating water supply to sprinkler zones.
-
Standpipe and Hydrant Systems – Controlling main water flow for firefighting.
-
Industrial Fire Protection Networks – Protecting factories, warehouses, and refineries.
Advantages in Fire Protection
Compared to other valve types, fire butterfly valves are more compact, require less maintenance, and can be integrated with monitoring systems for enhanced safety. Their simple structure ensures reliability during emergencies, where any delay could be costly.
In summary, the fire butterfly valve is an essential component in modern fire protection systems, providing quick, reliable, and space-efficient water flow control to safeguard lives and property.
