Air and vacuum relief valve for subsurface drip irrigation

This product is an air and vacuum relief valve used in subsurface drip irrigation systems. It is installed on irrigation lines to manage air movement within the pipeline during system operation and shutdown. The valve allows trapped air to exit the line during filling and permits air to enter as water drains, helping maintain normal line conditions. It features a compact housing designed for installation in small valve or emitter boxes. The valve body is made from rust-resistant materials suitable for outdoor and buried applications and includes threaded connections for standard plumbing fittings. This component is used when installing or maintaining subsurface drip irrigation systems to support proper line filling and drainage during routine watering cycles.
