Improving Access to At-Home Dialysis Treatment

Humphrey Products has expanded its diaphragm isolated iDP Series 2- and 3 port solenoid valves used successfully in kidney dialysis equipment over the past 30 years. Added to the line-up is the unique MiDP (motorized inert diaphragm poppet), a proportional valve that provides consistent variable flow performance and with improved features to maximize function.

We’re committed to producing top-rated medical device valves that deliver on our promise of providing our customers with the latest solenoid valve technology. Our valves are compact and durable, making them appropriate for repetitive functions and dialysis treatment applications.

iDP Kidney Dialysis Valve Features

The diaphragm isolated solenoid valve has recently added FFKM elastomers to the Radel and EPDM or VitonGF wetted materials, improving its range of chemical compatibility. In addition, it can withstand fluid temperatures up to 203° Fahrenheit, and the encapsulated coil allows for reliability in wet environments.

The iDP valve can meet the demands of diverse dialysis applications. It’s built and tested to achieve a minimum of 5.3 SLPM at 40 psid for liquids.

Additional features include:

  • Loctite impregnated coils that tolerate saline submersion
  • 2- and 3-way valve types
  • Manifold mount option
  • Servo valve driver for unmatched proportional control (MiDP)
  • New FFKM premium elastomer for extreme chemicals and temperatures

The unique design of our hemodialysis valves provides better response times, lower temperature ratings, improved temperature ranges, and market-leading reliability and elastomer options.
