- Operation T18B-V2
General:
The inside of the bellows valve adopts a bellows structure, and the lower end of the stainless steel bellows is welded on the valve stem to prevent the process fluid from eroding the valve stem. The other end is placed between the valve body and the valve cover to form a static seal. Double seal design If the bellows fails, the stem packing will also avoid leakage. The bellows is welded to the valve stem to maintain stable running performance and avoid the valve stem vibration caused by the valve plug vibration. It is most suitable for pipelines of steam, flammable, explosive, heat transfer oil, high purity, toxic and other media.
Working principle:
The equipped smart positioner will convert to valve required settings when receive normal signal of electricity or signal of computer. Then the pneumatic actuator linear displacement will change to angular displacement by valve special connections, and tested by position transducer then feedback to microprocessor.
The microprocessor will compare the actual valve feedback with original settings and tested if there is any deviation. It will output pulse width modulation command(PWM) to piezoelectric valve according to the the size and direction of deviation. The piezoelectric valve will regulate the input or exhaust gas under the control command.
