Product Announcement from FLSmidth
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.
The FLSmidth Type SK One-Way Cutoff Valve is available in six basic sizes. The 3 through 6-inch (75 -150 mm) valves match the I.D. of standard Schedule 40 pipe. The 8 and 10-inch (200 and 250 mm) valves match the I.D. of standard Schedule 30 pipe. Operating temperature up to 400° F (205° C).
Durable machined cast iron construction.
The valves employ replaceable hardened seats and discs, ground and lapped to ensure positive sealing. Air cylinder actuator provides fast and positive cutoff operation. 50 to 100 PSlG (3.5 to 7 Kg/cm2) clean plant air required.
Weather-proof (NEMA 4) limit switches are included for positive indication.
