General
YSIQ(D)60 series of intelligent angle control valve uses modular design to achieve a compact structure. The varieties of combination of components make it applicable in any circumstances which contain high pressure difference, high-viscosity-like or granular-like fluid, as well as situations where there is serious flashing and cavitations or piping is required to be direction changeable.
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.
Control Mode
Control mode apply PWM (Puise Width Modulation) to drive:
Full speed: when control deviation is big, positioner output link signal.
Mid-speed: when control deviation is normal, output impulse signal.
Slow speed: when control deviation is small, output smaller impulse signal.
Keep orientation: when control deviation is smaller than valve control precision range, no output command signal.
