The working principle of pneumatic control valve pneumatic characteristics and classification

Pneumatic pneumatic control valve is compressed air as power source, cylinder as actuator, and by means of electric valve positioner, converters, solenoid valve, a valve to drive the valve such as attachment, realize the switch quantity or proportion type adjustment, industrial automation control system receives the control signal to complete conditioning pipeline medium: flow, pressure, temperature and other process parameters. Pneumatic pneumatic control valve is to control the characteristics of simple, quick response, and intrinsically safe, do not need another explosion protection measures. Working principle of the pneumatic pneumatic control valve is compressed air as power source, cylinder as actuator, and by means of electric valve positioner, converters, solenoid valve, a valve to drive the valve such as attachment, realize the switch quantity or proportion type adjustment, industrial automation control system receives the control signal to complete conditioning pipeline medium: flow, pressure, temperature and other process parameters. Pneumatic pneumatic control valve is to control the characteristics of simple, quick response, and intrinsically safe, do not need another explosion protection measures. Classification according to the valve action mode can be divided into: straight stroke and stroke in two ways. Control simple quick response characteristics of intrinsically safe, do not need another explosion protection measures.
