Valbart™ Type
Ball Valves SubType
Rising Stem Ball Valves- Extended service life and low maintenance costs due to unique helix coil stem design, which enables friction-free opening and closing
- Improved product quality, efficiency and safety with tightness performance up to ANSI FCI-70-2 Class VI
- Easy in-line inspection and maintenance enabled by top-entry design
- Reduced corrosion due to heavy wall thickness in excess to ASME/ANSI B16.34
- Improved personnel safety from blowout-proof stem that meets international standards of API 600 and 6D
Other Features:
- Combination of a quarter-turn ball valve with a linear movement of non-rotating stem
- Trunnion mounted design
- Reduced or full bore
- Single seat (no valve body cavity)
- Unidirectional or bidirectional
- Metal to metal seat with stellite welding overlay (soft seat insert on request)
- Outside screw and yoke for adjusting of stem packing
- Blowout proof stem
- Suitable for very high frequent cycling operations (switching valves)
- Tight shut-off by means of application of external mechanical force and not dependent on differential pressure
- Proper selection of materials to avoid galling and high friction
- Protected lower trunnion against solid particles intrusion
- Clearance control to consider high/low temperature shrinkages
- Self-cleaning closure member
