The comparison of pneumatic valves and other valves

in the field of industrial pipes, valves and valve actuators is pipes that are widely used in the control equipment. Currently widely used in chemical industry, water and electricity, etc. Distinguish it from all kinds of situation, pneumatic valves and other valves have their own characteristics. Pneumatic high-pressure ball valve, pneumatic valve, the use of gas as a driving force, relative power drive, reduce the accident from power supply, so is relatively safe. But because of its simple mechanism, control accuracy will decrease slightly. Compared with the pneumatic high-pressure ball valve, electric valve, accuracy and stability. And because the electric drive, relatively easier to operate. But due to the complicated structure, service life will be relatively short. Relative pneumatic pressure, hydraulic control valve ball valve and the electric valve, higher accuracy and stability. And safety performance is also higher. But the cost will be more expensive, relatively and will be more complicated to use. If not high accuracy and high security requirements, cost performance is not as good as the former two.
