Handwheel Automatic Control Valve for Water / Oil / Steam Pressure Balanced

Pneumatic diaphragm intelligent high differential pressure cage control valve with handwheel

YSIQ(D)33 series of intelligent cage control valve is a pressure-balanced control valve which uses a cage guide balanced plug and a double hard sealing structure. It has a compact structure and its flow pipe is S streamline which make it applicable in any circumstances which contain high temperature, high pressure difference and low noise. This would meet the requirements from different users.

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.
