Product Details
MiDP S391 Series 2-port Stepper Operated Proportional Valve is ideal for precise control of bodily fluids, aggressive chemicals and cleaning fluids. The stepper motor design allows for precision variable flow control, excellent repeatability and the ability to hold a flow value with no/minimal power consumption. This new design utilizes the same industry leading media isolation of the field proven iDP 350 Series. The Radel™ body material and choice of FFKM, FKM or EPDM diaphragm-poppet elastomers allow for aggressive media use at elevated temperatures. Diaphragm-isolated design will not compromise performance or stepper motor. MiDP is also available in S390 inline / body ported configuration.
