A high pressure 6-port/2-position-valve to direct streams of mobile phase and
sample to different directions (e.g. via loop to column or directly to column).
The two-position 6-port injection valve is driven by a stepper motor. Only five
of the six ports are used (port 3 is not used). A lever/slider mechanism
transfers the movement of the stepper motor to the injection valve. Two
microswitches monitor switching of the valve (bypass and mainpass end
positions). The injection valve has a ceramic stator, Vespel rotor seal (Tefzel
seal available), and stainless-steel head. Three screws hold the head and
internal components in place. No valve adjustments are required after
replacing internal components.
