A manual control valve is a device that regulates fluid or air pressure through direct operator adjustment rather than automated signals. In plastic tubing extrusion, manual pressure control valves like OLC's MicroAir I series use a precision 30-turn knob to set and maintain ultra-low air pressure levels inside extruded tubing, ensuring consistent outside diameter and wall structure.
