Proportional control valve is the process of the implementation of the use of proportional and integral two calculations combined with the electric valve, the calculated value is farther away from the set value, the faster the stepping motor action, basically an attenuation of the sinusoidal waveform. Proportional control valve of the electric valve in addition to the valve body also have an actuator, because the installation of the reason, the equipment is generally lower into the upper out, so are installed in the return. Pneumatic control valve for continuous control with PID function Model 7000 is a control valve with intelligent positioner, through the position sensor on the valve, the electrical control system and microprocessor can do continuous position control, but also through the internal function to achieve continuous process control (PID function).
