FAQ
Q: What is a fire signal butterfly valve?
A fire signal butterfly valve is a type of butterfly valve equipped with a supervisory signal device (tamper switch). It is used in fire protection piping systems to control water flow and provide open/close position feedback to a fire alarm control panel.
Q: Where is it commonly used?
It is mainly used in fire sprinkler systems, hydrant systems, and other fire water supply pipelines to:
Isolate parts of the system during maintenance.
Monitor valve status (open/closed).
Q: How does it work?
Butterfly valve function: Rotating the disc 90° opens or closes the flow.
Signal function: A tamper switch detects valve position and sends a signal to the fire alarm system.
Supervision: If the valve is closed (or tampered with), the fire alarm panel will trigger a supervisory signal.
Q: What types of fire signal butterfly valves exist?
Wafer type – Compact, installed between flanges.
Grooved type – Easy installation with grooved couplings.
Flanged type – Heavier duty, bolted to pipeline flanges.
Q: What is the main advantage of a fire signal butterfly valve?
It integrates flow control + status monitoring in one device, improving fire system safety and making maintenance easier.
