Cheminerts new C62 series liquid handling valve is our first integrated motor/valve assembly designed specifically to be built into an OEM system. Using the well-proven Cheminert LC valve design and the 24 volt motor from our popular microelectric actuators, the C62 needs only to be connected to the instruments power supply.

Control is simplified to require a single contact closure; the injectors position is determined by whether the closure is held high or low. Theres even an easy way for the instrument to confirm the valves position by sensing the output from a built-in sensor.

In the default control mode, a contact closure moves the valve from Position A to Position B, where it remains until the contact is broken. A simple jumper change shifts the mode to dual contact closure, in which one contact closure shifts the injector to inject and a second is required to shift it back to load. Jumper settings can also be modified to change the motors degree of rotation so it can be used with any of the valve models available.

All these features are built into a compact and lightweight package, available in 4, 6, 8, and 10 port configurations, with a choice of fittings.
