Product Features
- Standard construction of body-bonnet connections are bolted bonnet or welded bonnet type.
- Full die forged structure for all pressure containing parts.
- Flanged valves are provided with flanges integral with the body forgings.
- Standard gasket design for bolted-bonnet valves is spiral wound type up to class ASME 1500. Ring Joint gaskets are standard for ASME 2500 and above. SPW/RJ are available on request for all pressure classes as option
- High quality packing (acc.to API 622) for reliable tightness and low emission performance in fully compliance with API 624.
- Standard seat design is screwed-in type, integral type is available as an alternative construction.
- High flow capacity port sizes and disc retraction minimize flow velocities and maximize valve service life.
- Outside Screw and Yoke (OS&Y).
- Low operation torque design.
- Self-aligning two-piece packing gland.
- Body-guided disc for prefect seat and disc alignment.
