High Pressure Proportional Regulator QKL-B1S.B2S/QKL-B3H 、 Industrial application ◆ Compact ◆ High Precision ◆ High Sensitivity ◆ Wide Pressure Range ◆ Laser Cutter ◆ Leak Tester ◆ Tension Control ◆ PET bottle molding machine ◆ Multi-Stage Pressure Control Product Description 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 ISO134

High Pressure Proportional Regulator QKL-B1S.B2S/QKL-B3H Product Precautions The valve can be mounted in any position. For very low pressure control, works best when mounted upright. And Ensure a minimum closed end volume of 40c.c. to allow proper functioning. Before piping is connected, it should be thoroughly blown out with air (flushing) or washed to remove chips, cutting oil and other debris from inside the pipe. Wrapping of Sealant Tape When screwing together pipes and fittings, etc., be certain that chips from the pipe threads and sealing material do not get inside the piping.
