1, Uses: Pneumatic V-shaped control valve is a kind of right-angle rotary structure, which is used with the valve positioner to achieve proportional adjustment; V-type valve is most suitable for a variety of regulatory occasions, with a large rated flow coefficient, adjustable ratio Large, good sealing effect, zero adjustment performance, small size, can be installed vertically. Suitable for controlling gas, steam, liquid and other media. 2, Features: Pneumatic V-type control valve is a kind of right-angle rotary structure, by the V-valve body, pneumatic actuators, locators and other accessories; there is an inherent equal flow characteristics of the same ratio; Small torque, with excellent sensitivity and induction speed; Super shear capacity. 3, Pneumatic piston actuator uses compressed air as the power source, through the movement of the piston crank to carry out 90-degree rotation, so that the valve automatically open and close. Its components are: adjusting bolt, actuator box, crank arm, cylinder block, cylinder shaft, piston, connecting rod and cardan shaft. 4, pneumatic control valve works: Pneumatic control valve by the implementing agencies and regulatory agencies. Actuator is the thrust member of the regulating valve, which generates the corresponding thrust according to the magnitude of the control signal pressure and drives the adjusting mechanism to act. The valve body is the regulating part of the pneumatic control valve which is in direct contact with the regulating medium to regulate the flow of the fluid. The right of the stomatal intake, the actuator internal piston to move on both sides, driven by the middle of the output shaft rolling, travel angle just 90 degrees, the valve fully open. The left of the stomatal intake, the actuator internal piston to move to the middle, driven by the middle of the output shaft rolling, travel angle is 90 degrees, the valve is fully closed. Simply put is on the right hole vent valve open, on the right of the vent hole valve, if the scene of gas source failure, sudden gas, the valve to maintain its original position.
