DUCO Bidirectional Perimeter Seated Valve with Cone Deflector

Features and Benefits

1. Perimeter seating guarantees bi-directional bubble-tight shutoff. Cavity-free body design prevents de-watering of pulp stock and is ideal in slurries, powders, plastics, and other solids handling applications

2. The addition of a Cone Deflector protects and extends the integrity of the perimeter seat in heavy solids, slurries, and abrasive applications

3. Elastomer seat is mechanically retained between body halves preventing movement or separation from the body, unlike standard o-ring seated valves

4. Precision machined body halves serve as scrapper blades, which clean the gate and 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. All NPV/DUCO Valve body castings are of 317SS (CG8M). Cone deflectors are available in 317SS and 420SS heat-treated and hardened to RC60

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

8. 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

9. Two-piece body design allows for the option to use the standard perimeter seat or replaceable cartridge seats depending on the requirements of the application
