Bmag 1/2 DN15 DN20 DN25 Automatic Working Pressure Temperature Wholesale Heating System Brass Air Vent Valves. This automatic air vent valve uses a float mechanism to release trapped air from heating and water systems automatically, so no manual bleeding is needed and the system keeps working. Made from solid brass with a corrosion resistant surface, this air vent valve handles high working pressure and temperature. Standard 1/2 inch BSP thread fits most radiator and pipeline connections directly, so installation is quick and simple with common plumbing tools for professional and DIY use. Suitable for radiator heating systems, central heating, solar water heaters and hot water pipelines, this air vent valve keeps air out of the loop and protects pumps from dry running.
