Uses and features: 1. Uses: It is a right-angle rotary structure, which is used with the valve positioner, can achieve proportional adjustment; V-type valve is most suitable for a variety of regulatory occasions, with a large flow coefficient, adjustable ratio , Good sealing effect, zero adjustment performance, small size, can be installed vertically. Suitable for controlling gas, steam, liquid and other media. 2. Features: It is a right-angle rotary structure, which consists of a V-shaped valve body, a pneumatic actuator, a positioner and other accessories. It has an inherent flow characteristic of approximately equal to one hundred percent. It adopts a double-bearing structure with a small starting torque, Good sensitivity and speed of induction; Super shear capacity. 3. Pneumatic piston actuator uses compressed air as the power source, driven by the piston crank for 90 degrees 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 regulating 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. Working principle: When the air intake on the right side, the piston inside the actuator moves to both sides, driving the middle output shaft to roll, the stroke angle is exactly 90 degrees, making 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.
