Lochinvar L100208447 Pressure Relief Valve 925 Mbh 30 Psi

Product Description

The LOCHINVAR L100208447 is a pressure relief valve rated at 30 psi and 925 MBH, designed to protect hydronic heating systems from dangerous overpressure conditions. When system pressure exceeds the set threshold, the valve opens automatically to discharge water and relieve excess pressure, preventing equipment damage or failure. With a 3/4-inch female inlet and 1-inch female outlet, this valve meets ASME standards for pressure relief in commercial and residential hot water heating applications. Licensed plumbers and HVAC technicians install this valve as a required safety component on boilers and water heaters.

This pressure relief valve is suited for hydronic boiler systems where overpressure protection is required by code. The 925 MBH ASME rating makes it appropriate for higher-output boiler installations common in commercial or large residential settings. It is typically installed on the boiler supply or vessel port designated for pressure relief, with the discharge piped to a safe drain location per applicable codes.

Key Features

• 30 psi pressure rating for reliable overpressure protection
• 925 MBH ASME-rated capacity for high-output boiler applications
• 3/4-inch female inlet x 1-inch female outlet connection
• ASME-rated pressure relief type for code-compliant installations
• Automatic activation at set pressure threshold to protect system components

Compatibility

Designed as an OEM-style replacement pressure relief valve for LOCHINVAR boiler and water heating systems requiring a 30 psi, 925 MBH ASME-rated pressure relief valve with 3/4-inch female inlet and 1-inch female outlet connections.

Installation Notes

Installation of pressure relief valves must comply with applicable mechanical codes, including ASME and local plumbing authority requirements. Shut down and depressurize the system before replacing this valve. The discharge outlet must be piped to an open drain or safe location to prevent injury from hot water discharge. This work should be performed by a licensed plumber or qualified HVAC technician.
