Product Description

The wafer-type signal butterfly valve is an intelligent fire protection valve that integrates flow control, status monitoring and remote alarm. It is not only the switch of the pipeline, but also the "sentinel" of the reliability of the fire protection system. The valve body itself does not have a flange. A long bolt is passed through the bolt holes on the valve body to "clamp" it between the two pipe flanges. A precise electromechanical device (usually a microswitch) is connected to the valve stem or handle through a mechanical linkage mechanism.

 • When the valve is fully open, the signal module outputs a "normal" signal (usually for closing or opening the circuit) to the fire control center.

 • Once the valve is turned from the fully open position (usually by more than a certain Angle, such as 10°), the signal module will be immediately triggered to send a "supervisory alarm" or "fault signal" to the fire control center.

Features

  • Continuous Valve Monitoring: Instant alerts if the valve is not fully open.

  • NFPA Compliance: Meets code requirements for valve supervision.

  • Space-Saving Wafer Design: Ideal for tight spaces and cost-sensitive projects.

  • Rugged Supervisory Switch: Built for reliable performance in demanding environments.

  • Easy Integration: Simplifies connection to standard fire alarm control panels.

FAQ

Q:What is its main function?

A:Its core functions are twofold: one is to control the on-off of water flow like a common valve; Second, it can remotely and in real time monitor the status of the valve (mainly open or closed), and send an alarm signal to the fire control center when the valve is abnormally closed, ensuring that the fire water source is always on standby.

 

Q:How to choose between wafer-type and flange-type butterfly valves with signals?

A:Wafer type: Compact structure, light weight, and low cost. It is suitable for projects with limited space and tight budgets

      Flange type: More stable connection, good sealing performance, and convenient for disassembly and maintenance. It is suitable for occasions with significant vibration, large pipe diameters or high requirements for maintenance convenience.

 

Q:What’s the MOQ for wafer butterfly valve ?

A:For standard sizes, our MOQ is usually 20 Sets . For large sizes or special requirements, the MOQ can be one unit. We are always willing to provide customers with flexible solutions.

 

Q:What is the delivery time?

A:The production usually takes 15 to 45 days. For large or special orders, it may take 60 days or longer. We will provide you with an accurate production plan after placing your order.
