Signal Butterfly Valve

Through the factory of FUXEON® for customization,the signal butterfly valve consists of a butterfly valve body and a signal device. You can make the purchase at the factory of FUXEON®.The valve body controls the water flow by rotating the valve plate around the axis, featuring a compact structure, quick opening and closing, and is suitable for installation environments with limited space. The valve body material is mainly ductile iron or carbon steel, which is strong and durable with a long service life. The other part is the signal device, which triggers a micro-switch when the valve opens or closes to a specific angle. The switch signal can be transmitted through the circuit to the fire alarm controller.

Parameter

Function:

The flanged signal butterfly valve not only serves the purpose of opening and closing water flow but can also be monitored by the fire alarm system, thereby providing real-time feedback on the on/off status of the valve through the signal device.

worm wheel signal butterfly valves have common connection types, namely flange connection, grooved connection, and wafer connection. The corresponding connection type can be selected according to different pipeline conditions.

The signal device of the wafer type signal butterfly valve is connected to the fire alarm control panel. When the valve is accidentally closed or partially closed, the system will immediately sound an alarm to prevent the fire protection system from failing due to valve closure.

FAQ

Q1: Which pipeline systems are signal butterfly valves suitable for?

A: Signal butterfly valves are widely applied in fire protection systems, water supply and drainage, HVAC, industrial pipelines, municipal engineering and water treatment systems. They are ideal for scenarios requiring remote monitoring of valve on-off status, especially fire sprinkler risers, fire water mains, building automation pipelines and industrial safety interlock systems.

Q2: What types of media can signal butterfly valves handle?

A: They are suitable for clean media such as water, air and oil, as well as mild corrosive liquids and sewage. Soft-seal models (EPDM/NBR/PTFE seals) are suitable for non-corrosive media like fire water and domestic water, while hard-seal models can handle slightly corrosive media. They are not recommended for high-concentration corrosive fluids or media with large solid particles.

Q3: What are the core application advantages of signal butterfly valves?

A: Besides the compact structure and quick 90° quarter-turn operation of ordinary butterfly valves, their core advantage is the built-in signal device (limit switch, micro switch), which can feedback on-off status to control panels or fire alarm systems remotely. They enable real-time monitoring, prevent misoperation, and ensure system safety, with reliable sealing and cost-effectiveness.
