Low Pressure Proportional Regulator(0-8bar)
Product Serial: QKL-B1T.B2T/QKL-B3-1.B3-2/QKL-B3-1A

This series is a complete closed loop servo system consisting of two solenoid valves, an internal pressuretransducer, and electronic controls. Based on analog signal, the pressure is controlled by two solenoidvalves to maintain precise pressure; one valve functions as inlet control, the other as exhaust. The pressureoutput is measured by an internal or an external feedback pressure transducer that provides a feedbacksignal to the electronic controls. The regulator is suitable for industries that require precise pressurechanges 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 pressuretransducer comes with B1T, B3-1, and B3-1A series, whereas B2T and B3-2 uses an external pressuretransducer 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.
