The series of five fully customizable miniature isolation valves 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 .38 in., .75 in. and 1 in. to correspond to orifice diameters from .032 in. to .125 in. within a broad range of applications. A selection of two-way normally open, two-way normally closed and three-way configurations is offered.
