let it flow

Does a thermostatic valve control the hot flow and let the cold flow freely, or does it control the cold flow and let the hot flow freely? Or does it close one off as it opens the other?
And while I have the attention of you thermostatic experts; How fast is a "fast" responding thermostatic valve? Several seconds?, about 1 second?, small fraction of a second? Do all thermostatic valves also incorporate a pressure balance to handle the sudden changes while the thermostat slowly adjusts for the long term temperature?
