Pneumatic diaphragm intelligent cage control valve

YSIQ(D)30 Series of Intelligent Cage Control Valve is a kind of pressure-balanced control valve. It uses cage oriented balanced plug type, double hard sealing and impact structure with S streamline flow type, make it applicable for high temperature, high pressure head and low noise condition, to meet customers operation requirements.

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.
