FLSmidth Type SK One-Way Cutoff Valves are designed to provide a positive cut-off and seal for pressure and vacuum pneumatic conveying lines. The valves can be used at inlet and outlet locations on conveying pressure tanks. The cut-off valve can also be used on branched systems to permit selection for line activation or to prevent short-circuiting of a conveyor by stopping airflow through an unused section. Air cylinder operated for quick, responsive cut-off.
