Brass Automatic Air Vent Pressure Valve 1/2' Male This Brass Automatic Air Vent Pressure Valve with a 1/2' male connection is designed to automatically purge entrapped air from closed hydronic and heating systems. The brass body provides durability and corrosion resistance, making it suitable for hot water and boiler loops, radiant flooring, and other closed circuits. The vent operates automatically to remove air without the need for manual bleeding. Key benefits Automatically vents air from the system, helping maintain flow and efficiency Reduces the need for manual bleeding and periodic maintenance Helps prevent airrelated noise, noise and pump cavitation, and uneven heating Brass construction offers durability and corrosion resistance in hot water and heating environments Simple installation with a standard 1/2' male thread for compatibility with common ports and fittings No external power required for operation, providing reliable performance in typical residential and light commercial applications Key attributes Material: Brass Connection: 1/2' Male Type: Automatic air vent Function: Automatically vents trapped air from the closed loop Compatibility: Suitable for hydronic heating, radiant floor systems, and other closedloop hot water circuits Mounting/installation: Designed for standard 1/2' ports and fittings Performance: Continuous air removal to improve system efficiency and protect components Applications and use cases Residential boiler or baseboard heating systems where air accumulation can reduce efficiency and cause noise Radiant floor heating loops that require ongoing air removal for even temperature distribution Closedloop solar thermal systems or other hot water circuits where air pockets can impede flow and performance Specifications alignment Product name reflects Brass Automatic Air Vent Pressure Valve with 1/2' Male connection Key materials, size, and connection type match typical 1/2' male threaded air vent installations Designed for automatic, maintenance operation within standard hydronic and hot water systems
