ARVXMicro exhaust valveIn general, water contains about 2VOL% dissolved air. During the water delivery process, this air is continuously released from the water and accumulates at the high point of the pipeline, forming an air pocket (AIR POCKET), making water delivery difficult. The main function of this micro exhaust valve is to remove the 2VOL% dissolved air, and it is suitable for installation in high-rise buildings, factory piping, and small pump stations to protect or improve the water delivery efficiency of the system and save energy.
The single rod micro exhaust valve is a valve body similar to an elliptical shape, with all internal components including the float, lever, valve seat, etc. made of 304 stainless steel. It uses a standard exhaust aperture of 1/6 "and is suitable for use in PN16 working pressure environments. Medium temperature: 0-80 ℃.
ARVXMicro exhaust valveMainly used in HVAC systems, it is often installed at high points or bends to remove excess gas from pipelines. Medium temperature: 0-80 ℃.
