General:
YSIQ(D)10 Series of Intelligent Single-Seat Control Valve use modular design, with advantages of impact structure and wide varieties. The varieties combination of the trim components, make it applicable for high pressure difference, high precision and low noise conditions to meet the different usage for customers’ requirements. The modular design, double-sides valve seat and compressing tightly connection, all greatly enhance valve sealing grade and its service life, which make it easy to repair and greatly increase its general performance.
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.
