Boiler Pressure Relief Valve, 3/4 Inch, FNPT, Discharge Line Flood Sensor Connection Included

A pressure relief valve designed to protect hot water heating systems from excessive pressure buildup. Commonly used in boiler applications, this valve automatically relieves system pressure at a preset level of 50 PSI, helping prevent damage to equipment, piping, and related components. Constructed with a durable bronze body, the valve is built for long‑term performance in demanding heating environments. It features a non‑metallic disc‑to‑metal seat design for dependable sealing and automatic reseating, along with a test lever that allows manual operation for periodic inspection and maintenance.

The pressure relief valve includes 3/4 inch NPT female inlet and outlet connections for easy installation into standard piping systems. It is designed to handle temperatures up to approximately 250 Degrees F and has a high discharge capacity suitable for large heating systems. A key feature of this model is the integrated discharge line flood sensor with SentryPlus Alert technology. This sensor detects excessive discharge from the relief valve, helping identify potential system issues or failures before they cause damage. When paired with an activation kit, the sensor can connect to building management systems or monitoring platforms for real‑time alerts.
