The S&S® RVB Series™ segmented V-notch ball control valve is designed for applications that demand very high flow capacity with reliable control.
Its straight-through flow path and segmented ball geometry deliver significantly higher Cv than globe valves, making the RVB Series ideal for high-flow, low pressure drop services in liquids, gases, and steam.
Available in ANSI Class 150 and 300 flanged configurations, the RVB Series supports both throttling and on/off service. Forward-flow sealing improves shutoff performance, while the compact body design simplifies installation and reduces potential leak paths.
Multiple seat and trim options allow the RVB Series valves to be configured for a wide range of process conditions.
High-Capacity Segmented Ball Design – Straight-through flow path and V-notch ball geometry provide significantly higher Cv than globe valves in a compact envelope
Stable Control Performance – Predictable rotary control characteristics deliver smooth throttling across a wide operating range for liquids, gases, and steam
Flexible Shutoff Options – Soft and metal seat constructions support ANSI Class IV or Class VI shutoff for control and tight isolation
Durable Construction – Robust body and trim materials withstand demanding service conditions and extend service life
Low Emission Packing Options – PTFE and graphite-based packing sets support fugitive emission and high-temperature requirements
Automation-Ready Platform – Splined shaft interface supports direct mounting of SPC’s RS, RC, and RE valve actuators with digital positioners
