What are the advantages of electric control valve and pneumatic control valve?

1. Electric regulating valve:
The electric actuator accepts 4-20mA current signal, changes the cross-sectional size between the valve core and the valve seat according to the relative displacement (straight stroke arrangement and angular stroke) caused by the forward and reverse rotation of the motor, and manipulates the total flow, temperature and working pressure of the pipeline material and other main processing parameters. Advantages of electric regulating valve: remote control, intelligent system operation, fast attitude, suitable for long-distance transmission; energy saving (only power consumption during operation), environmental protection (no carbon emission), easy installation (no complicated pneumatic pipelines and pumping platforms).

2. The pneumatic control valve:
Pneumatic control valve uses compressed gas as the power device, the cylinder as the electric actuator, and the gate valve is driven by accessories such as electric/pneumatic valve positioner, converter, vacuum solenoid valve, and retention valve. (relative movement of valve core and valve seat) to complete on-off or proportional adjustment, accept control signal: 4-20mA current signal and convert electrical signal into working pressure signal (through positioner or vacuum solenoid valve) to adjust the total amount of pipeline material The main parameters of various processing processes such as flow rate, working pressure, temperature, etc. Advantages of pneumatic control valve: simple structure, reliable and stable posture, large drawing force, convenient installation and maintenance, low price, fireproof and explosion-proof.
