Sanitary air relief valve is a reliable, automatic air – relief valve which is installed vertically on the top of a pipeline or container, or before the inlet of a pump, where air releasing is required.
The valve body is composed of two parts and assembled by a clamp. The lower body has a welding/clamp tube. This air release valve is a double-seat valve with a freely movable Polypropylene (PP) ball. The ball, which is lighter than water, can close the upper/lower seat according to the conditions of pressure.
