Bio-Chem Valve and Omnifit’s new miniature isolation valves are a series of five quick-response valves for handling aggressive and high-purity fluids featuring a range of materials, configurations and performance characteristics. The valves have a flexible "mix and match" construction that is determined by solenoid shell size, manifold mountability and flow configuration. The isolation design restricts fluid contact to only the valve diaphragm and valve body, which are made of inert materials. The standard isolation valves are constructed with chemically inert PTFE wetted materials. For other mechanical and chemical compatibility requirements PEEK™, PPS or Tefzel® are available for the body material and EPDM, Viton® or perfluorelastomer are available for the diaphragm material. Valve shell diameters are available in 9.7mm, 19mm and 25mm to correspond to orifice diameters from 0.8mm to 3.2mm within a broad range of applications. A selection of two-way normally open, 2-way normally closed and 3-way configurations is offered. The isolation valves, designed for applications in which space is limited, are also available in manifold-mountable versions.
