Single Seat Pneumatic Control Valve is composed of new multi-spring pneumatic actuator and top-oriented straight through low-flow single seat valve. Equipped with pneumatic control valve positioning or control valve positioned, with electrical signals and compressed air as the driving force to accept the control system input 0-10mA DC or 4-20mA DC current signal, the regulator will transfer compressed air into air pressure signal to input or output, can achieve split control(segment signal), thus changing the valve opening displacement, to precise control and adjust the fluid medium process parameters.
