DUCO Bidirectional Perimeter Seated Full Port Cavity Free Design
Features and Benefits
1. Perimeter seating guarantees bi-directional bubble-tight shutoff
2. Elastomer seat is mechanically retained between body halves preventing movement or separation from the body, unlike standard o-ring seated valves
3. Full port cavity free body design prevents de-watering of pulp stock and is ideal in slurries, powders, plastics and other solids handling applications
4. Precision machined body halves serve as scrapper blades, which extend the life of the packing system
5. Two-piece body design simplifies repair/replacement of gate, packing, seat ring, and top works assembly
6. Non-rise stem design eliminates potential safety hazards caused by rising stem valves and performs better in high-vibration areas
7. All NPV/DUCO Valve body castings are of 317SS (CG8M)
8. All external valve components: stanchions, bolting, bridge, stem, clevis, packing follower- are stainless steel which eliminates external corrosion
9. Precision machining of the stuffing box with the live-loaded packing in conjunction with an additional Viton O-Ring provides for a very dependable and adjustable packing system
10. Two-piece body design allows for the option to use the standard perimeter seat or replaceable cartridge seat depending on requirements of application
