• Medium pressure Proportional Regulator (0-30bar)
Medium Pressure Proportional Regulator (0-30bar)
Product Serial: QKL-B1S.B2S、B3H

This series is a complete closed loop servo system constransducer, and electronic controls. Based on analog signal, the pressure is controlled by two solenoidvalves to maintain precise pressure; one valve functions as inlet control, theoutput is measured by an internal or an external feedback pressure transducer that provides a feedbacksignal to the electronic controls. The regulator is suitable for industriesthat require precise pressurechanges at any time and monitor pressure values.Available with 3 selections of input sig4-20mA, or RS485 Modbus. Monitor signal can be chosen from 1transducer comes with B1S, B3H-1 series, whereas B2feedback (ideal for when the vessel is distant away from the regulator)
All our products have CE, SGS, RoHS certification with ISO13485 quality system.
