The series of five customizable miniature isolation valves available from Bio-Chem Valve and Omnifit feature a flexible "mix and match" construction that is determined by solenoid shell size, manifold mountability and flow configuration. Valve shell diameters are available in 0.38, 0.75 and 1.00 in. to correspond to orifice diameters from 0.032 to 0.125 in. within a broad range of applications. A selection of two-way normally open, 2-way normally closed and 3-way configurations is offered.
