BRISTOL BV-G31 2.5″ Grooved Butterfly Valve

Compact UL/FM Supervised Valve for Fire Protection Systems

🔍 Overview – Built for Compact Fire Safety Installations

The BRISTOL BV-G31 2.5″ Grooved Butterfly Valve is a precision-engineered, space-saving valve designed for fire protection systems. Manufactured in the UAE by BRISTOL, this valve is UL Listed (EX16012) and FM Approved, providing certified performance and long-term reliability.

Its compact design makes it perfect for installations in tight mechanical rooms, fire risers, and sprinkler zones where supervision, pressure handling, and code compliance are non-negotiable.

⚙️ Engineering & Pressure Performance

Designed for 300 PSI working pressure and 600 PSI hydrostatic testing, the BV-G31 handles demanding fire protection environments with ease. Despite its short 96.4 mm length, the valve maintains structural strength and consistent flow control.

Whether it’s integrated into a fire pump header, zone isolation section, or retrofit system, it guarantees smooth and secure operation even under high pressure.

🛠️ Construction Materials & Coating Protection

The valve body is made of ductile iron (ASTM A536), known for its strength and resistance to mechanical stress. To protect it from corrosion and weather, the body is coated inside and out with epoxy. The disc and seat assembly, made from EPDM-coated ductile iron, ensures a leak-tight seal and excellent durability.

Together, these materials offer years of maintenance-free service, even in harsh indoor or outdoor conditions.

🔩 Installation Compatibility – Fast and Flexible Integration

The grooved ends comply with ANSI/AWWA C606, allowing fast and secure installation using standard grooved couplings. The ISO 5211 top flange provides an interface for tamper switches or gear operators, making it supervision-ready.

This enables facility managers to easily monitor valve position (open/closed), an essential feature in fire system compliance, insurance inspections, and remote monitoring setups.

🧱 Compact Dimensions – Ideal for Tight Spaces

Thanks to its 96.4 mm length, the 2.5″ version of the BV-G31 valve offers unmatched performance in compact layouts. It’s the preferred choice for:

• 🏗️ Mechanical rooms with limited space

• 🔥 Sprinkler risers in small buildings

• 🛠️ Retrofitting older systems with modern components

Its compact footprint doesn’t compromise pressure handling or code compliance.
