Wager’s model 1500-1 vent check valve is mounted vertically on the deck of a ship. In the open position, the valve allows for required ventilation. During heavy seas, our disc style float rises to a buna seat, and prevents water and debris from entering tanks and bulkheads. 

 

A 30 x 30 mesh stainless steel screen provides protection from deck fires. It is available in galvanized steel, and stainless steel. Special request are needed for aluminum and bronze.
