High Differential Pressure Automatic Control Valve for Gas / Steam / Water Balanced

 

Pneumatic diaphragm intelligent pressure balanced high differential pressure control valve

 

 

General

     YSIQ(D) 24 series of intelligent pressure-balanced low noise control valve uses modular design to achieve a compact structure. The special symmetric holes on the valve trim are able to reduce the noise and further reduce the pressure in order to prevent the flashing and cavitation; and make it applicable in nay circumstances which contain high pressure difference and low noise; and to meet higher requirements from users. Double side usable valve seat and body are connected by pressing method, which effectively improved the valve sealing level and stability; and made usage and maintenance very convenient which greatly improved the general performance of control 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.
