YSIQ(D)50 series of intelligent 3-way control valve uses a structure with double plug, upper and lower guide. According to the path, it is divided into three-way diffluence valve (one inlet two outlet) and three-way confluence valve (two inlet one outlet) in order to achieve the fluid mixing heating or cooling, or not equivalent diffluence which would meet the requirements of users. It is especially suitable for fluid temperature regulation in the petroleum industry heat exchanger.
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 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.
