This series is a complete closed loop servo system consisting of two solenoid valves, internal pressure transducer, and electronic controls. Based on analog signal, the pressure is controlled by two solenoid valves to maintain precise pressure; one valve functions as inlet control, the other as exhaust. The pressure output is measured by an internal pressure transducer of B1S or B3H-1 series and provides a feedback signal to the electronic controls. As for B2S or B3H-2, there is an extra piece of external pressure transducer for feedback to maintain higher accuracy.
This series of proportional valve input signal has a selection of 0-5VDC, 0-10VDC or 4-20mA, and also has RS485 ModBus communication output that is used to output the monitor signal required for data acquisition or quality assurance to the panel or controller; and the monitor output has a selection of 0-10V or 4-20mA.
