Pneumatic control purpose and characteristics of pneumatic valve

the purpose of the pneumatic valve, pneumatic control and characteristics:
its utility is a quarter-turn structure, it has to do with pneumatic valve positioner, proportional control can be realized; V pneumatic valve core is the most suitable for all kinds of regulating occasions, with large rated flow coefficient, adjustable than large, good sealing effect, sensitive regulation performance, small size, can be installed in vertical lie. Apply to control gas, steam, liquid medium.
is characterized by a quarter-turn structure, by V pneumatic valve, actuator, positioner of and other accessories. There is a best than the intrinsic flow feature of such as approximation; With double bearing structure, small starting torque, has excellent sensitivity and speed of induction; Strong ability of shear.
, pneumatic piston actuators using compressed air as power source, through the movement of the piston drives the crank arm for degrees of rotation, to make the pneumatic valve open/close automatically. Part of it is: the adjusting bolt, actuator housing, crank arm shaft, piston, connecting rod, cylinder block, cylinder, cardan shaft.
the working principle of pneumatic valve, pneumatic control, pneumatic control pneumatic valve is made up of actuators and regulating mechanism. Actuator is adjust the thrust part of pneumatic valve, it according to the size of the control signal pressure produce corresponding thrust, promote regulating mechanism. Pneumatic valve body is the adjustment of the pneumatic valve pneumatic control components, it is directly contact with control agent, regulating the flow of the fluid.
summarizes characteristics: pneumatic control pneumatic valve control is simple, quick response, and intrinsically safe, do not need another explosion protection measures. Pneumatic control valve with compressed air as the power, realize the switch quantity or proportion type adjustment, based on cylinder actuators, industrial automation control system control reception to complete can regulate the flow of pipeline medium, pressure, temperature and other process parameters.
