Its working principle is: set the target pressure difference value on the intelligent pressure difference electric actuator, detect the pressure difference value at both ends of the controlled load through two pressure sensors, and calculate the actual pressure difference value and the target pressure difference value through PID calculation. The actuator outputs the control signal to change the opening of the valve, thereby stabilizing the pressure difference between the two ends of the load. This product is suitable for heating and venting central air conditioning, building automation, chemical industry, energy, fire-fighting light industry, environmental protection, pharmaceuticals, etc. Balanced industries and occasions.
