  • Micrometric valve actuator device for gas pressure control
    Patent number: 12049964
    Abstract: The present invention addresses to a device that allows the control of the gas pressure at the outlet of a fixed bed adsorption equipment operated at high pressures, by means of the actuation of a micrometric valve (6), wherein the valve must be located downstream of the equipment. The valve actuation takes place by means of a stepper motor (1), controlled by a microcontroller board (22), which connects to the valve shaft by means of a system of pulleys (2, 5) and belt (3). The present invention is applied in adsorption units, in which other gases are present, by altering the tuning parameters of the PID controller or even being used in a liquid medium or gas-liquid two-phase flow.
