Burnham 81660505 Pressure Relief Valve 1.25x1.5 15 PSI

The Burnham 81660505 is a pressure relief valve designed specifically for residential boiler heating systems. This essential safety component features a 1.25-inch inlet connection and a 1.5-inch outlet connection, engineered to protect your heating system from excessive pressure buildup by automatically releasing fluid when the preset 15 PSI pressure limit is reached.

Key Features:

• 15 PSI pressure relief rating for residential steam and hydronic boiler applications
• 1.25" x 1.5" connection size for proper system integration
• Threaded connection design for straightforward installation
• Durable construction with high-quality materials for reliable, long-term performance
• Automatic activation when system pressure exceeds safe operating limits
• Genuine Burnham OEM replacement part

This relief valve is a critical safety device that prevents dangerous pressure conditions in your boiler system. When pressure reaches the 15 PSI threshold, the valve automatically opens to discharge excess pressure, then reseats once pressure returns to safe levels. Proper installation requires mounting in an upright position with pressure entering from the bottom, and the discharge must be piped to a safe drainage location per local codes.
