<p>A rotating flow control valve has at least two concentric sleeves (5, 8), preferably cylindrical, rotating inside an outer housing (2). The sleeves and the housing are provided with apertures and the inlet to the valve is axial with the outlets radial. The sleeves are set using control grips (13, 14) on concentric shafts (10, 11). The overall flow settings are a combination of the relative settings of the apertures in the sleeves and housing.</p> |
