Original Press Release:


Inert Proportional Valve


The Inert Proportional Valve (IPV) is a proportional, solenoid-operated diaphragm isolation valve designed for use with corrosive or high-purity fluids commonly found in the medical equipment, water purification and clinical chemistry industries.

The IPV provides infinitely variable flow control in an economical package and is well suited for closed loop applications. Flow is proportional to the magnitude of the current input into this 24 VDC (nominal) valve driver. The poppet and seat are configured to provide bubble tight leakage characteristics. This valve is rated to 60 psi and is available with numerous porting and electrical connection options.

The materials of all surfaces in the flow path are inert and impervious to a wide range of aggressive fluids. Body material choices include Ultem® (polyetherimide) and Radel® R (polyphenylsulfone). The fluid path is isolated from the solenoid by a diaphragm constructed of either EPDM (ethylene propylene) or Viton® GF.
