Xylem-Bell & Gossett 110132 1" ASME Bronze Safety Relief Valve 50 PSI 1,710,000 BTU/Hr

The Xylem-Bell & Gossett 110132 (Model 1170-50) is an ASME-rated bronze safety relief valve designed to protect fired and unfired hot water pressure vessels against hazardous overpressure conditions. This professional-grade valve features a 1-inch NPT inlet and 1-inch NPT outlet in an angle pattern configuration, factory set to relieve at 50 PSI with an impressive capacity of 1,710,000 BTU/hr.

Key Features:

• ASME certified and manufactured in accordance with Section IV of the ASME Boiler and Pressure Vessel Code
• Bronze body construction with EPDM diaphragm-assist operation for superior durability and corrosion resistance
• Diaphragm-assist design provides approximately 5 times greater effective area than conventional "pop-type" relief valves to overcome fouling effects
• Unique fail-safe disc maintains safety relief function even in the event of diaphragm rupture
• Low differential between opening and closing pressures prevents water flashing to steam and system hammering
• Maximum operating pressure: 125 PSI
• Maximum temperature rating: 250°F
• Compact dimensions: 2-7/8" length x 4-15/16" height

Ideal for commercial and industrial hydronic heating systems, hot water boilers, direct-fired water heaters, and storage tanks with indirect heat exchangers. Bell & Gossett relief valves are certified by the National Board of Boiler and Pressure Vessel Inspectors and offer the highest BTU ratings available in their class.
