Inert Diaphragm Valve handles aggressive fluids.

Press Release Summary:



Three-way IDV solenoid-operated diaphragm isolation valve works with fluids found in medical equipment, water purification and clinical chemistry industries. Materials of all surfaces in flow path are inert and impervious to many aggressive fluids. Valve is typically used in waste circuits where valve must tolerate high contaminant levels. Valve is rated 35 psi with Cv of 0.22 and is available in 2- and 3-way versions.

3-Way Inert Diaphragm Valve


The 3-Way Inert Diaphragm Valve (IDV) is a 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 valve is commonly used in waste circuits where the valve must tolerate aggressive fluids and high contaminant levels (solids).

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. The valve is available with 5/16" (8mm) quick disconnects for tool-less assembly and service. Numerous fluid and electrical connections are available. The valve life is in excess of 40 million cycles.

The valve is rated for 35 psi (bi-directionally) with a Cv of 0.22 and is available in 2-way and 3-way versions. For other pressure rating please call or e-mail South Bend Controls.
