Description

Valbart RSBV Rising Stem Ball Valves are the oil and gas industry’s choice for applications requiring a mechanically energized metal or soft seat to prevent losses from process contamination or material leakage. The are ideal for frequent cycling. 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 General Industries Other Industries Basic (Organic & Inorganic) Biofuels
