YSIQ(D)10J Series of Intelligent Jacketed Insulation Control Valve mainly applied to the occasions of thermal insulation, full the heat medium into the gap between valve body and metal jacket to keep thermal insulation and prevent fluid crystallization occurs, as well as the increase of viscosity, which due to the temperature reduction.
?
ZM10 series multi-springs pneumatic reinforce actuator, makes the valve realize the conversion of normal close and normal open on site easily, the spring can be effectively protected from the corrosion to prolong the service life of actuator and convenient for customers operation. The actuator and the intelligent valve positioner are connected pipeless to strengthen the antisemitic performance,stability and precision adjustment, to meet to exactly control of the working conditions.
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.
