1、WORKING PRINCIPLE: The working principle of pneumatic pressure regulating valve is using compressed gas as power source, with the cylinder as the actuator, and with the help of valve positioner, converter, solenoid valve, holding valve, gas storage tank, gas filter and other accessories to drive the valve, to achieve switching volume or proportional regulation 2、RIGHT ANGLE PROPORTIONAL REGULATION: Pneumatic control valve is a right angle rotation structure, and the valve positioner matching use, can achieve proportional regulation 3、WIDE APPLICATION: V type valve core is most suitable for various adjusting occasion, with large rated flow coefficient, large adjustable ratio, good sealing effect, sensitive adjustment performance, small size, can be installed vertically 4、ADJUSTABLE MEDIUM: Air pressure regulator is suitable for controlling gas, steam, liquid and other media 5、STRUCTURE COMPOSITION: Pneumatic piston actuator adopts compressed air as power source, and drives the bending arm to rotate 90 degrees through the movement of the piston, so as to make the valve open and close automatically. The components include adjusting bolt, actuator box, curved arm, cylinder block, cylinder shaft, piston, connecting rod and cardan shaft
