Bellow Sealing Automatic Control Valve Single Seat Pneumatic Pressure Balanced
Pneumatic diaphragm intelligent pressure balanced bellow sealing single-seat control valve
General
YSIQ(D) 20V series of intelligent pressure-balanced single-seat control valve uses modular design to achieve a compact structure. Valve plug with balance holes and imported sealing ring together made a special double sealing realized; and make it applicable for high differential pressure occasions in order to meet users’ requirements. 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 size and direction of deviation. The piezoelectric valve will regulate the input or exhaust gas under the control command.
