AVK Valves Swing Check Valves are primarily designed and manufactured for the prevention of flow reversal and
- SWING
are suitable for potable water or sewage applications. The operation of the valve is fully automatic allowing liquid
- LEVER AND WEIGHT
to flow in one direction only. The function of the external lever and weight, where fitted, is to provide additional
- LEVER, WEIGHT AND GUARD weight loading to the valve disk, thus giving mechanical assistance towards closure. The position of the weight is
adjustable and allows the closure rate to be varied to suit the actual working conditions.
