The Weil-McLain 383600065 is an ASME-rated pressure relief valve designed for use with a wide range of Weil-McLain commercial and residential boilers. This valve is set to open at 80 PSI, providing critical overpressure protection for hydronic heating systems. It features a 3/4 inches NPT female inlet connection, making it a direct-fit replacement for compatible Weil-McLain boiler installations. Pressure relief valves are essential safety components in any hot water or steam boiler system. When system pressure exceeds the set point, the valve opens automatically to release excess pressure and prevent damage to the boiler, piping, and connected equipment. Without a properly functioning relief valve, a boiler system can become dangerously over-pressurized, creating serious safety hazards. The Weil-McLain 383600065 meets ASME standards, which means it has been tested and certified to perform reliably under the demanding conditions found in commercial and residential heating applications. HVAC technicians and plumbing professionals rely on ASME-certified relief valves to meet code requirements and ensure safe system operation. This valve is compatible with Weil-McLain 76, 78, 80, and 86 Series boilers, as well as LGB, MGB, and Ultra Commercial boiler series. Whether you are performing a boiler replacement, completing a routine maintenance inspection, or upgrading an aging safety valve, the 383600065 is a proven OEM-specification part. Keeping a properly rated relief valve installed and in good working order is a fundamental requirement for any code-compliant hydronic heating system.
The Weil-McLain 383600065 delivers ASME-certified overpressure safety for a broad range of Weil-McLain commercial and residential boilers, with a standard 3/4 inches NPT female connection and an 80 PSI set point for dependable, code-compliant operation.
