For Difficult Gases and Liquids, Use Humphrey’s Compact, High-Flow iDP Models
Humphrey iDP inert Diaphragm-Poppet Solenoid Valves are designed to control difficult media, including bodily fluids, cleaners, reagents, and aggressive fluids. Our iDP is constructed of materials suitable for fluids at elevated liquid temperatures as well.
The iDP is perfect for life science equipment, analytical devices, and kidney dialysis. It’s also adaptable for clinical chemistry, agent detection, environmental monitoring, food and beverage, and gaseous flow control.
Engineering Behind The iDP Diaphragm-Poppet Solenoid Valves
The engineered flexing diaphragm of FKM, FFKM, or EPDM is clamped between the molded inert body and the encapsulated coil. The coil design produces a high force to create a tight valve seal and is encapsulated to withstand humid environments. The diaphragm safely isolates the media from the solenoid element and provides rugged, durable performance for millions of cycles.
Controllable Liquid Media
Check your media compatibility charts for elastomers and body materials before investing in iDP. Humphrey inert solenoid valves can control:
- human blood and bodily fluids
- saline solutions
- citric acid
- ethyl and methyl alcohols
- ethylene glycol
- acetic acid
- hydrogen peroxide
- Others, consult factory
