Humphrey iDP 350 & 351 Serie

Humphrey 350 & 351 solenoid valve: Flexibele High-Flow Montage

The Humphrey 350 and 351 solenoid valve series offers powerful liquid control for applications that require high flow capacity. The crucial difference between these two models is the way they are integrated. The 350 is suitable for direct inline mounting, while the 351 fits specifically on a manifold. Inacom supplies both versions of this inert solenoid valve directly to the medical and analytical sector.

Smart mounting choices with the 350 and 351 series

When designing complex liquid systems, the available space often determines the choice of housing. That is why the Humphrey 350 solenoid valve is ideal for "direct piping" applications where you place the valve straight into the pipework. In addition, the Humphrey 351 solenoid valve with its manifold mount (subbase) offers the perfect solution for compact systems. This minimises the number of leak points and saves valuable space in your machine.

Key features of this high-flow series

Both models in the 350/351-serie use Humphrey's superior iDP technology. They also share the following advantages:

• High flow capacity: With an orifice of 3,1 mm, these valves offer excellent flow of up to 2,9 LPM (water).
• Complete media isolation: Thanks to the diaphragm-isolated design, the medium only comes into contact with the inert Radel® housing and FKM or EPDM seals.
• Inline vs. Manifold:
  • Type 350: Inline ports (1/8-27 NPSF) for easy direct connection.
  • Type 351: Manifold interface for fast mounting on a common block.
• Reliability: Built for millions of cycles, even when using aggressive cleaning agents or reagents.

Applications in industry

The choice between the Humphrey 350 and 351 often depends on the system architecture in sectors such as:

• Laboratory automation: The 351 (manifold) is widely used in compact analysis lines.
• Industrial cleaning: The 350 (inline) is a favourite for direct integration into supply lines for aggressive liquids.
• Medical dialysis: Safe and reliable liquid control in critical patient care equipment.
