●2-liquid mixture Mixes liquids A & B at a constant rate. The KFPV050 series and KFPV300 series allows seamless control of the flow rate in accordance with changes in the input signal size. Now a single control valve can perform multiple-level flow control that normally requires multiple ON/OFF type solenoid valves. - Page 4 4. Food and drink dispensers, and more shortened service life.
