Talking about the Adjustment Performance of Pneumatic Actuator and Electro-hydraulic Actuator
Since the air is compressible, the stability of the pneumatic transmission system is poor, which has a great impact on the accuracy of position control and speed control. Therefore, the positioning signal of the pneumatic actuator usually produces an execution error with a resolution of about 3~5%. This leads to inaccurate valve positioning correction, the valve should be closed but not closed, and at the same time, it cannot be positioned due to the execution error caused by the resolution,

What should be paid attention to in the valve
In industries that require temperature, high and low temperature cycle temperature control system equipment has been widely used, which can realize two functions of heating and cooling. During cooling and heating, the temperature change in the thermostat can be realized by the circulation of the fluid medium (refrigerant), so as to achieve the temperature required by the process. 1. What is the function of the valve of the high and low temperature cycle temperature control
