What valve should I choose to accurately adjust the gas flow in the pipeline? If you want to adjust the angle of the valve accurately, it is best to achieve a resolution of 0. 1.

If you want to adjust accurately, generally choose electric control valve, its accuracy is much higher than that of pneumatic control, and its sensitivity and response time are also better than that of pneumatic control. Therefore, if leakage is allowed in the application, you can choose electric actuator and low-load butterfly valve; if leakage is not allowed, you can choose V-ball valve. Of course, these all depend on the application temperature, so as to make a better choice.
