928-103

This 1/2-inch Hot Water Tank (HWT) Vacuum Relief Valve, also known as a vacuum breaker, is a critical safety component designed for pressurized water heating systems and boilers. It automatically vents the system to atmosphere when a vacuum is created, protecting the storage tank from structural damage or collapse caused by negative pressure. This valve is essential for preventing back-siphonage of contaminated water into the potable water supply during drainage or sudden pressure loss. Engineered for durability and reliable performance, it is a standard safety requirement for maintaining the integrity of hot water tanks, solar water heaters, and steam-supplied equipment.
Type: Boiler and Water Heater Safety Valve
Size: 1/2-inch NPT
Application: Residential and commercial water heaters, boilers, solar heating systems, and pressure vessels to prevent vacuum-induced tank failure and back-siphonage.
Specifications: 1/2" male NPT connection, automatic operation, atmospheric venting capability, suitable for hot water supply applications.
