No the valves are not spring loaded. They are basically friction fit, but they require a solid pull to open and solid push to close. There is no slop in the action. I think they are likely cheap (although they do the job) plus they work in tight plumbing spaces where you can operate them with the finger pull ring (if not jammed that is) and close with a simple but solid push down. The pictures in included previoulsy is the low point drain valve from the low pressure side of my water pump. I replaced it with a flex hose to minimize pump vibration; and also added a flex hose on the high pressure side too, but retained the drain valve on that side. Winters here are colder than a witches arm pit, so pink antifreeze is the plumbing cocktail of choice.
