• 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 consisting of two solenoid valves, an 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 or an external feedback pressure transducer that provides a feedback signal to the electronic controls. The regulator is suitable for industries that require precise pressure changes at any time and monitor pressure values.Available with 3 selections of input signal: 0-10VDC, 4-20mA, or RS485 Modbus. Monitor signal can be chosen from 1-5V, 0-10V, or 4-20mA. Internal pressure transducer comes with B1S, B3H-1 series, whereas B2S and B3H-2 uses an external pressure transducer for feedback (ideal for when the vessel is distant away from the regulator)
 All our products have CE, SGS, RoHS certification with ISO13485 quality system.
