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.
