I've just completed several illustrations of our valves. (+1 if you like !)

This four port diversion valve offers an alternative method to the three port valve we offer. Cold flow will enter port A and exit out of port D without flowing through B. Hot flow will activate the wax motor inside causing the internal valve to close forcing fluid through the system cooler and back into port C of the valve and ultimately out of port D.

The two images in this post feature our 4 port diverting valve, and its two states (hot and cold).  Keep in mind that the two positions shown here are at opposite sides of the thermal spectrum for this product; this valve will modulate positions between the two extremes shown to achieve the proper control required by your system.
