YSIQ(D)50 Series of Intelligent Three-way Control Valve uses double plug, upper and lower guide structure. According to the path, they are two types, which are three-way diffluence valve (one inlet port two outlet ports) and three-way confluence valve (two inlet ports one outlet port), to achieve the fluid mixing heating, cooling and un-equivalent diffluence purpose to meet the customers operation requirements. This series valves are specially suitable for fluid temperature regulation on heat exchanger of petroleum industry .
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.
