Fireguard Air Release Valve FGAV101

The Fireguard Air Release Valve FGAV101 is a high-performance automatic air relief valve designed for fire protection systems, water pipelines, and pump applications. This valve plays a critical role in maintaining system efficiency by automatically releasing trapped air from piping systems while operating under pressure.

The Fireguard Air Release Valve FGAV101 is specifically designed for use in wet pipe sprinkler systems and on the casing of horizontal split-case pumps. It ensures the continuous release of small pockets of accumulated air, preventing air build-up that can negatively affect system performance.

Air accumulation in pipelines can lead to reduced efficiency, flow restrictions, and potential pressure surges. The Fireguard Air Release Valve FGAV101 eliminates these issues by continuously venting trapped air, ensuring smooth and uninterrupted system operation.

This valve is designed to operate under pressure conditions exceeding atmospheric pressure. It features a small orifice mechanism that allows controlled release of air without allowing water loss, maintaining system pressure and efficiency at all times.

The Fireguard Air Release Valve FGAV101 is constructed from high-quality ductile iron, ensuring strength, durability, and long service life. Internal components such as the float, lever, and seat ring are made from stainless steel (AISI 304), providing excellent corrosion resistance and reliable performance even in demanding environments.

The valve includes a precision-engineered float mechanism that automatically opens and closes the air release orifice based on the presence of air within the system. When air accumulates, the float drops, allowing air to escape. Once the air is released and water reaches the valve, the float rises and seals the orifice, preventing water leakage.

The Fireguard Air Release Valve FGAV101 is coated with fusion bonded epoxy, which complies with AWWA C550 standards. This coating provides excellent protection against corrosion and ensures long-term durability in harsh environments.

The valve is designed to operate at a maximum working pressure of 200 PSI, making it suitable for fire protection and water distribution systems. It also supports a wide operating temperature range of -10°C to 120°C, ensuring reliable performance under varying conditions.

The valve is equipped with threaded connections (NPT / BSPT / BSPP), allowing easy installation and compatibility with standard piping systems. It is available in sizes such as ½”, ¾”, and 1”, making it suitable for different applications and system requirements.

According to the datasheet (page 1 – material list and specifications), the valve includes ductile iron body and cover, stainless steel float and internal components, and Viton orifice button, ensuring durability and high performance.

The Fireguard Air Release Valve FGAV101 is UL Listed and FM Approved, confirming compliance with international fire protection standards. This makes it suitable for use in commercial, industrial, and infrastructure projects worldwide.

Maintenance of the valve is minimal due to its automatic operation and robust construction. Periodic inspection is recommended to ensure proper functioning of the float mechanism and internal components.

Overall, the Fireguard Air Release Valve FGAV101 is an essential component in fire protection systems. Its ability to automatically release trapped air, maintain system pressure, and prevent water hammer makes it a reliable and efficient solution for modern fire safety infrastructure.
