Overview

This air-release vacuum break valve allows air to evacuate while filling a pipeline or tank. It also permits air intake while draining to prevent vacuum formation. Install one wherever air is most likely to collect or at the highest elevation points in a system. The elbow at the top has female NPT threads, allowing for connection to a hose or pipe to contain any minor spillage. Meanwhile, the valve checks and further protects against the admittance of dirt or debris into the system.
