Oil / Water / Steam Automatic Control Valve with Cast Stainless Steel JIS DIN GB
Pneumatic diaphram intelligent high differential pressure control valve
YSIQ(D)70 Series of Intelligent High DP Control Valve mainly used for power plant high pressure boiler occasions which feed water need to be regulated, in case cavitation, cavitation erosion happened when valve is on small opening.
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.
