Description
Self-operating float-type combination air release valve designed to be fitted at any high point on a pipeline. Capable of discharging large volumes of air during filling, admitting air during draining, and purging entrapped air under pressure. Incorporates an anti-shock (non-slam) mechanism to mitigate water hammer.
