BRISTOL 8″ Grooved Butterfly Valve (BV-G31)
UL/FM Supervised Valve for Fire Protection Piping Systems
🔍 Product Overview – Engineered for Fire Safety Compliance
The BRISTOL BV-G31 8” Grooved Butterfly Valve is a high-performance flow control device built specifically for fire protection systems. It is UL Listed (EX16012) and FM Approved, ensuring global compliance for critical safety infrastructure. Manufactured in the UAE and distributed internationally, this valve is ideal for use in fire pump rooms, commercial fire sprinkler networks, and industrial fire suppression systems.
⚙️ Design & Construction – Built for Strength and Efficiency
This valve features grooved-end connections that meet ANSI/AWWA C606 standards, allowing quick and secure installation. The top flange interface, compliant with ISO 5211, ensures easy integration with gear operators, tamper switches, or remote supervision devices.
Its supervised capability lets facility managers monitor the valve’s status (open or closed), adding an extra layer of control to fire systems where timely response is critical. The valve is rated for 300 PSI working pressure and 600 PSI hydrostatic test pressure, making it suitable for high-pressure applications.
To withstand various operating environments, the valve is rated for temperatures up to 80°C (176°F). This makes it suitable for both indoor and outdoor installations in different climatic zones.
🏗️ Material Specifications – Durable, Leak-Free Performance
The valve body is made from Ductile Iron (ASTM A536), offering superior mechanical strength and shock resistance. The disc is also ductile iron, coated in EPDM rubber, which ensures a tight, leak-proof seal and excellent chemical resistance.
Both the interior and exterior of the valve are fully epoxy coated, enhancing protection from corrosion, UV exposure, and harsh environments. This level of protection ensures long-lasting service, even in outdoor or high-humidity installations.
