How does Pneumatic valve work
- Apr 05, 2018 -

Pneumatic valve How to work: Pneumatic valve is a kind of air compression to control the valve of the metal pneumatic valve, it has greatly facilitated the relevant industry engineering operations, but also for enterprises to save a lot of energy costs. Useful to the pneumatic valve of the enterprise staff must understand its working principle, as well as the correct method of operation, can be accurate to carry out the operation. Pneumatic piston actuator using compressed air as power source, through the movement of the piston to drive the curved arm 90 degrees of rotation, to achieve the valve automatic opening and closing.

Its components are: adjustment bolts, actuator body box, curved arm, cylinder body, cylinder shaft, piston, connecting rod, universal axis small and beautiful, lightweight JIS standard stainless steel cut-off valve

Range migration function, range migration ratio 100:1

Damping: 0-32 seconds adjustable, step in 0.1 seconds

0 Point ﹑ Full degree compensation correction function

Output current multi-point correction

Display multiple monitoring variables, pressure units optional

Output current root function.

With self-diagnosis and fault alarm output function.

With EEPROM nonvolatile memory, not afraid to lose the power loss of data and the original calibration data recovery function. 

Through Hart communication hand operator and is the button to realize remote ﹑ is the parameter setting and function configuration. Pneumatic piston Actuator for dual function: The gas source signal pressure which is output by the double acting locator is input to the left and right two gas chambers of the actuator piston respectively, because the gas source pressure of the left and right two gas chambers of the input piston is different, the pressure difference is formed, the piston is driven straight, and the gear and rack drive

The piston's linear movement is converted into the rotating motion of the actuator spindle, until the left and right gas chamber pressure is balanced, the movement stops, the valve stem and the spool are rotated while the actuator rotates, and the circulation area between the valve core and the valve seat is changed to achieve the regulating purpose; Pneumatic piston Actuator For single action: The gas signal pressure input from the single acting locator is entered into the gas chamber without the spring side of the actuator, and the gas signal pressure acts on the difference between the thrust and the spring force formed on the piston, the cylinder piston acts as a straight line movement through the gear, the rack drive, Until the gas signal pressure to form the thrust and the spring force balance, the movement stops, in the execution mechanism spindle rotates the valve stem, the valve core makes the rotation movement, thus changes the valve core, the valve seat between the circulation area, achieves the adjustment goal.
