1" Brass Circulator Flange with Ball Valve, with Drain, Sweat

1" Brass Circulator Flange with Integrated Ball Valve – Precision and Performance for Hydronic Systems

The 1" Brass Circulator Flange with Ball Valve is a high-efficiency solution designed to simplify pump isolation and improve system serviceability in hydronic heating applications. Combining a circulator flange and full-port isolation valve into a single, rugged assembly, this product is ideal for professionals seeking to streamline installations and reduce leak paths.

Built to Perform in Demanding Environments

Manufactured from heavy-duty forged brass, this flange is engineered for long-term durability, high-pressure tolerance, and thermal resistance. Its uni-body construction reduces the number of connections required, minimizing the potential for leaks and saving time during installation. The integrated ball valve provides reliable shutoff, while a drain port enables fast, controlled purging or maintenance.

Key Professional Features

• Forged Brass Construction – Corrosion-resistant and pressure-rated for 600 PSI WOG.
• Integrated Full-Port Ball Valve – Maximizes flow and supports precise system control.
• Compact Uni-Body Design – Replaces multiple components and reduces up to five leak points.
• Conical Inlet – Enhances flow characteristics and minimizes turbulence.
• Blowout-Proof Stem – Improves safety under pressure and long-term reliability.
• Hi-Flow Drain Port – Allows for efficient draining during service without additional fittings.
• Serviceable Packing Gland – Provides easy access for adjustment and long-term maintenance.
