Conbraco 14-606-V12 2.5 Inch Vacuum Relief Valve 12 Inch Hg

The Conbraco 14-606-V12 is a 2.5-inch vacuum relief valve designed to protect tanks, vessels, and piping systems from damage caused by negative pressure conditions. This valve automatically opens at 12 inches of mercury vacuum (12"Hg) to allow air into the system, preventing dangerous implosion or collapse of equipment.

Key Features:

• 2.5-inch NPT connection size for medium to large capacity applications
• Precision-calibrated to open at 12 inches mercury vacuum pressure
• Durable construction suitable for industrial tank and vessel protection
• Automatic operation requires no external power or controls
• Helps maintain atmospheric pressure balance in storage tanks and process vessels
• Prevents vacuum formation during liquid drainage or temperature changes

This vacuum relief valve is commonly used on storage tanks, process vessels, heat exchangers, and piping systems where liquid removal, cooling, or condensation could create negative pressure conditions. The valve provides essential safety protection for equipment in chemical processing, petroleum storage, water treatment, and industrial fluid handling applications.
