Vee-Notch Ball Control Valve
High-performance segmented vee-notch ball control valves designed for exceptional modulation accuracy, high flow capacity, and reliable bi-directional sealing in critical process applications.
Advanced Vee-Notch Ball Control Valve Solutions
Engineered for precise flow control and high efficiency, our vee-notch ball control valves feature a segmented ball design that provides superior modulation accuracy across a wide flow range. The one-piece straight-through body maximizes flow capacity while minimizing pressure drop, and the clamped-in self-aligned bi-directional seat ensures dependable shut-off (up to ANSI Class VI). Featuring a splined shaft to eliminate dead band, these valves are available with wafer and flanged end connections and integrate seamlessly with pneumatic cylinder rotary actuators for precise and reliable automated process control.
