Pneumatic diaphragm intelligent pressure-balanced low-noise single-seat control valve

YSIQ(D)24 Series of Intelligent Pressure-balanced Low Noise Control Valve uses modular design and impact structure. Through the special symmetric holes on the valve trim, it could reduce the noise and pressure, thereby preventing from flashing and cavitation,make it applicable for high pressure difference and low noise conditions to meet customers requirements. Double-sides valve seat and compressing connection of the valve body, greatly enhance the sealing grade and service life of the valve lead, which make it easy to repair and greatly increase the general performance of the regulating valve.

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.
