Product Features

1. One-piece forged construction with a capless valve body design reduces leakage points between the valve body and cap, enabling online maintenance without removing the cap

2. Compared to vertical shut-off valves, the 60° angle design offers lower pressure drop

3. Non-rotating valve stem undergoes hardening and grinding polishing to minimize torque and prevent torsional damage to packing

4. Polished packing chamber and pre-compressed composite graphite rings ensure tighter sealing

5. Tungsten-chromium-cobalt alloy disc, seat, and back seat ensure extended service life even in demanding applications

6. Fully guided disc ensures seat-disc alignment remains unaffected by lateral thrust from high-velocity fluids, preventing body scoring, stem scratching or bending, and extending disc seal and body life

7. The back seat chamfer is located on the stem rather than the disc, complying with API-600 and API-602 requirements.

8. A larger clearance between the stem and disc allows the disc to move freely.

9. The intermediate material beneath the valve disc interior ensures non-rotational sealing between the plug and seat

11. Fully enclosed, lubricated stem drive system with dual needle bearings to minimize operating torque

12. Dust cap and sleeve protect the stem from contamination by dirt, dust, and sand

13. Excellent resistance to thermal expansion and contraction

14. Suitable for sewage and discharge applications

15. Optional dynamic packing load

16. Valve disc types include plug, needle, or globe check disc

17. Optional handwheel colors
