Characterized control valves
WebA segmented ball valve is similar to a conventional ball valve, but with a contoured V-notch segment in the ball. This control valve has good rangeability, control, and shutoff capability. The V-notch ball provides positive shearing action and produces an inherent equal percentage flow characteristic. WebThis category contains a variety of 2-way and 3-way Characterized Control Valves manufactured by Belimo. In order to ensure good stability of control, it is essential for a control valve to have an equal percentage …
