Description
High-capacity kinetic air release for large diameter mains. The KARX is a high-capacity combination air release valve designed for large diameter transmission mains where rapid venting of large air volumes is critical. The oversized kinetic orifice minimises back pressure during filling, reducing pipe stress and fill times. Continuous air release under pressure prevents air locking in rising mains and hilly pipeline profiles.
