Humphrey MiDP solenoid valve: Uiterst Nauwkeurige Proportionele Regeling
The Humphrey MiDP solenoid valve represents the next step in the evolution of liquid control. Unlike traditional valves, this series uses an advanced stepper motor for stepless and extremely accurate control of aggressive media. Inacom supplies this innovative MiDP technology to engineers who demand full control over their liquid flows.
Revolutionary control with the Humphrey MiDP solenoid valve
In complex analytical and medical processes, simple on/off control is often not enough. That is why the Humphrey MiDP solenoid valve offers a proportional solution in which you can match the flow exactly to your needs. Because the stepper motor opens or closes the valve in very small steps, you achieve a repeatability that is impossible with standard solenoid technology. In addition, the low hysteresis of less than 2% guarantees an extremely constant flow.
Key features of MiDP technology
The MiDP series (S390 and S391) combines the advantages of chemical isolation with the precision of digital control. You also benefit from the following advantages:
- Stepless flow control: The stepper motor ensures a smooth transition between different flows, which is ideal for mixing processes.
- Maximum chemical resistance: Thanks to the Radel® housing and FKM or EPDM diaphragms, the medium stays fully separated from the drive.
- High flow at high pressure: This valve easily handles liquid flows of up to 8,5 LPM at pressures of up to 4,1 bar.
- Inline and manifold: As with the standard iDP series, you choose between an inline (S390) or manifold-mount (S391) version for your system.
Applications in innovation hubs
The Humphrey MiDP solenoid valve solves complex challenges in various high-end sectors:
- Analytical instrumentation: Exact dosing of reagents for liquid chromatography and precision analyses.
- Process control: Accurate mixing ratios of different liquids in laboratory setups.
- Medical technology: Advanced flow control in dialysis equipment and patient support systems.
