NSF, UL Listed & AWWA Compliant Grooved Butterfly Valve with Signal Switch for Remote Monitoring and Safety Zone Control

Grooved Butterfly Valve( Hants Model HBF-300G), is designed to shut off or regulate water flow in piping systems. This model series is available in multiple certified options for different applications: a UL listed model for fire protection systems, an NSF-certified model for drinking water applications under NSF/ANSI/CAN 61 and NSF/ANSI 372, and a dual UL + NSF certified and AWWA-compliant model for multi-purpose municipal and commercial piping systems.

Application of Grooved Butterfly Valve With Signal Switch

• UL listed for fire protection applications, the valve is suitable for use as a primary control valve in fire protection piping systems, such as automatic fire sprinkler and standpipe systems, ensuring dependable on/off water flow control for rapid emergency response.
• Certified to NSF/ANSI/CAN 61 and NSF/ANSI 372 standards, the valve with Signal Switch is perfectly suited for municipal drinking water pipelines, water treatment plants, and potable water distribution networks, guaranteeing materials comply with strict non-toxic and sanitary standards.
• Offers a premium combined certification choice that satisfies both fire safety (UL) and drinking water purity (NSF/AWWA) regulations simultaneously. This eliminates the need for separate valve types in mixed-use commercial/residential buildings or multi-purpose industrial facilities.
• Equipped with an integrated signal switch, it is highly suitable for zone control stations in high-rise buildings and industrial parks. Installed upstream or downstream of alarm and deluge valves, it provides continuous remote monitoring, status indication, and advanced tamper detection.
• Utilizes a standard grooved end connection design, making it the perfect solution for fast-track projects, confined spaces, and piping systems that require frequent maintenance, inspection, or future reconfigurations with minimal downtime.

Key Features and Benefits of Grooved Butterfly Valve with Signal Switch

• Offers versatile purchasing choices to match specific project budgets and regulations. Customers can choose from UL Listed, NSF Certified, or a combined UL/NSF Certified & AWWA Compliant premium configuration.
• Features a built-in supervisory switch that connects directly to control panels or SCADA systems, instantly triggering an alert if the valve is closed or tampered with.
• Equipped with a prominent, high-contrast visual indicator that allows operators to instantly verify whether the valve is open or closed from a distance.
• Conforms to API 609 / AWWA standards with a streamlined disc that minimizes pressure drop, featuring high-strength ductile iron and premium epoxy coating for maximum corrosion resistance up to 300 psi.
• The standard grooved end design ensures faster, easier installation and maintenance compared to flanged valves, significantly reducing labor costs while accommodating minor pipe vibration.

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

Q1: What certification and quoting options are available for this butterfly valve?

We offer a flexible pricing structure based on your project requirements. You can choose from three configurations:

(1) UL Listed only for fire protection.

(2) NSF Certified only for potable water.

(3) Dual UL + NSF Certified & AWWA Compliant for multi-purpose municipal or commercial systems.

Please specify your preference when requesting a quote.

Q2: Can this grooved butterfly valve be used safely in municipal drinking water systems?

Yes. When ordering the NSF-certified or AWWA-compliant option, the valve is built with high-grade materials and coated with a food-grade, fusion-bonded epoxy. This ensures 100% compliance with strict non-toxic and sanitary regulations for potable water distribution.

Q3: What is the purpose of the Signal Switch on this butterfly valve?

The Signal Switch is a supervisory switch linked to the valve's gear operator. It monitors the Open/Closed status of the valve disc. If the valve is closed or turned away from its fully open position, it instantly alerts the central fire alarm panel to prevent accidental water shut-off in the sprinkler system.
