Electric rotary or selector valve is a stepper motor driven fluid handling valve designed for fluid selection and distribution and automated fluidics injection applications. The precise rotary valve provides automated routing of fluidic volumes for aggressive or reactive fluids. The inert path is achieved by aligning holes in a PCTFE rotor with holes in the valve body. There is an optical encoder inside the valve to provide accurate information of the position of the rotor. Users can easily program the valve controller to perform desired position sequence via the communication interface. The package includes sample Teflon tubing, standard 1/4''-28 fittings/ferrules, and RS 232/485 to USB converter etc.
