The Valbart Rising Stem Ball Valve (RSBV) is the oil and gas industry’s choice for applications requiring a mechanically energized metal seat or soft-seat to safeguard against losses from process contamination or leakage of material. Whether your needs call for molecular sieve switching, isomerization, thermal oil, high/low temperatures or critical services, the RSBV provides an unmatched level of robustness, reliability, and convenience.

Features & Benefits
- 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
- Combination of a quarter-turn ball valve with a linear movement of non-rotating stem
- Suitable for very high frequent cycling operations (switching valves)
- Metal to metal seat with stellite welding overlay (soft seat insert on request)
- Tight shut-off by means of application of external mechanical force and not dependent on differential pressure
- Protected lower trunnion against solid particles intrusion
