Frequently Asked Questions(FAQ) about Grooved Type Butterfly Valve With Signal Switch

Q1: What is the purpose of the Signal Switch on the UL Grooved Type Butterfly Valve with Signal Switch?

The Signal Switch on the UL Grooved Type Butterfly Valve with Signal Switch is a valve supervisory switch designed for fire sprinkler system monitoring. It monitors whether the butterfly valve remains in the fully open position.

When the valve is closed or moved away from its fully open position, the switch sends a supervisory signal to the fire alarm control panel. This helps alert maintenance personnel to possible valve tampering or accidental water shut-off, ensuring the sprinkler system remains ready to supply water during a fire emergency.

Q2: Why choose an NSF certified Grooved Type Butterfly Valve with Signal Switch?

An NSF certified Grooved Type Butterfly Valve with Signal Switch helps meet drinking water safety requirements while providing flow control and valve position monitoring in water supply systems. For projects that require potable water compliance, the NSF certified model provides documented certification support under NSF/ANSI/CAN 61 and NSF/ANSI 372, helping contractors and engineers select a valve suitable for drinking water-related applications.

Q3: What is the difference between the UL listed and NSF certified models of the HBF-300G Grooved Type Butterfly Valve with Signal Switch?

The HBF-300G Grooved Type Butterfly Valve with Signal Switch is available in different certified model options for different applications. The UL listed model is designed for fire protection systems, while the NSF certified model is designed for drinking water and water supply systems.

The UL listed model is mainly used in fire sprinkler systems, standpipe systems, and zone control stations. It includes a signal switch for valve position monitoring and helps prevent accidental water shut-off in fire protection piping.

The NSF certified model is mainly used for drinking water and water supply applications. This model has been certified to NSF/ANSI/CAN 61 (Drinking Water System Components – Health Effects) and NSF/ANSI 372 (Drinking Water System Components – Lead Content). These certifications help verify that the valve's wetted components have been evaluated and certified for potable water-related use.
