What is the difference between pneumatic ventilation control butterfly valve Hansen and electric control valve? a. The nonlinearity of the butterfly valve is used to compensate the nonlinearity of the process, so that the total gain of the system changes little and is stable; b. Process pipeline conditions, considering the resistance of process pipeline; c. Adapt to the load fluctuation of the system; d. Consider the working conditions and service life of the butterfly valve; e. The working characteristics of butterfly valve are improved.
、 Secondly, if it is installed on a horizontal pipe, the upper and lower parts should also be vertical to the pipe, but the lower part of the valve will be supported to ensure stability and reliability. For special occasions, the butterfly valve needs to be installed horizontally on the vertical pipeline, and also needs to be supported. Of course, during installation, it is also necessary to prevent some additional stress to the butterfly valve.
