Kadant Johnson 24a76400 Vacuum Breaker 1/2 Inch Ipm

Product Description

The KADANT JOHNSON 24a76400 is a stainless steel vacuum breaker designed to relieve unwanted vacuum conditions in closed vessels and pipelines. It features a 1/2 inch IPM inlet connection with a 3/8 inch threaded outlet and a straight piping configuration. Rated to 300 psi and 365 degrees F, this valve is built for demanding fluid handling applications. It prevents system collapse and backflow by automatically venting vacuum buildup, making it a reliable component for process piping, steam systems, and similar closed-loop configurations. Licensed plumbers and pipefitters are the typical installers for this type of valve.

This vacuum breaker is suited for industrial and commercial fluid handling systems where negative pressure control is critical. The straight piping configuration simplifies inline installation, and the stainless steel body provides corrosion resistance in wet or chemically active environments. Typical applications include process piping, condensate return lines, and any closed vessel or pipeline where vacuum relief is required to maintain system integrity.

Key Features

• Stainless steel body for corrosion resistance in demanding fluid handling environments
• Rated to 300 psi maximum working pressure
• Temperature rating of 365 degrees F for high-temperature service
• 1/2 inch IPM inlet connection with 3/8 inch threaded outlet
• Straight piping configuration for straightforward inline installation
• Relieves vacuum and prevents backflow or vessel collapse in closed systems

Compatibility

Designed as an OEM-style vacuum breaker for inline installation in closed vessels and pipelines requiring vacuum relief in fluid handling systems.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable codes such as the IPC or IFGC. Depressurize and isolate the system completely before removing any existing valve or fitting. Verify that the inlet connection size and thread type match the existing piping before installation. Do not exceed the rated pressure or temperature limits of the valve during service.
