Product description
The working principle of pneumatic pressure regulating valve is to use compressed gas as power source, air cylinder as actuator, and drive the valve with the aid of valve positioner, converter, solenoid valve, position maintaining valve, air tank, gas filter and other accessories to realize the on-off or proportional regulation.
Pneumatic control valve is a kind of right angle rotary structure, which is used with valve positioner to realize proportional adjustment; V-shaped valve core is most suitable for various adjustment occasions, with large rated flow coefficient, large adjustable ratio, good sealing effect, sensitive adjustment performance, small volume, and vertical and horizontal installation. Suitable for controlling gas, steam, liquid and other media.
The pneumatic piston actuator uses compressed air as the power source to drive the crank arm to rotate 90 degrees through the movement of the piston, so as to make the valve open and close automatically. Its components are: adjusting bolt, actuator box, curved arm, cylinder block, cylinder shaft, piston, connecting rod and cardan shaft.
