The Humphrey iDP inert Diaphragm-Poppet Solenoid Valves are specifically designed for control of difficult media, such as blood, cleaners, reagents, and aggressive fluids. Constructed of materials suitable for bodily fluids, aggressive chemicals & cleaners and elevated liquid temperatures, the iDP is perfect for equipment used for the life sciences, and on analytical devices and kidney dialysis. Other markets include clinical chemistry, agent detection, environmental monitoring, food and beverage, and gaseous flow control.

The engineered flexing diaphragm of FKM or EPDM is clamped between the molded inert body and the encapsulated coil. The diaphragm isolates the media safely from the solenoid element and provides rugged, durable performance for millions of cycles. The design produces high force to seal valve tight and incorporates encapsulated coil to withstand humid environments.

The iDP is offered in several models: 
      *  Compact 300 Series 2-Port Normally Closed, Inline or Sub-base ported,
      *   Compact 300 Series 3-Port Diverting Valve, Inline ported,
      *   High flow 350 Series 2-Port Normally Closed, Inline or Sub-base ported,
      *   High Flow 370 Series 3-Port Diverting, Inline or Sub-base ported,        
      *   New Proportional 390 Series 2-Port Normally Closed, Inline or Sub-base ported.  

Easy navigation to your inert solenoid valve selection and solid model CAD files, product specifications and support information is available via our Online Catalog.  Should assistance be needed, our application and engineering staff is ready to answer your questions, provide selection assistance and discuss any special requirements or modifications not found in the catalog.

Check your media versus compatibility charts for elastometers and body materials. Examples of liquid media Humphrey inert solenoid valves will control:
      *   human blood and biofluids
      *   lye
      *   bleach
      *   formaldehyde
      *   saline solutions
