DUCO Bidirectional Perimeter Seated Full Port Cavity Free Design

Features and Benefits

1. Perimeter seating guarantees bidirectional 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 dewatering 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 replacement of gate, packing, seat ring and topworks

6. Non-rise stem design is more compact and eliminates a potential safety hazard created by rising stem valves in restricted spaces

7. All NPV valve body castings are of 317 stainless steel

8. All external valve components – stanchions, bolting, bridge, stem, clevis, packing follower and lockout-are of stainless steel construction which eliminates external corrosion

9. Precision machining of the stuffing box with the live-loaded packing in conjunction with an additional Viton 0-ring provides for a very dependable and adjustable packing system

10. All manual valves are equipped with a stainless steel lockout bar. All automated valves are equipped with a stainless steel mechanical lockout and bar

11. Available in sizes 2” – 30”
