CBio-Chem - Electric Rotary Valves - Brochure

Our Electric Rotary Valve (ERV) is a stepper motor driven fluid handling valve. It provides an inert flow path for aggressive fluids. The inert path is achieved by aligning holes in a PCTFE rotor with holes in the PTFE body. ERVs are typically used in one of two main applications; port selection applications where one stream is diverted to one of multiple paths, and loop injection applications where the valve can be used to load and inject fluids into a sample loop in two discrete steps.
