What type of on/off water valve?

Question

My wife and I bought a new dishwasher from Home D***t and it was delivered today. The problem is they did not install it because they claimed the on/off water valve/fixture was the wrong type. Rather than your typical on/off valve that you turn left or right to turn the water on and off, the fixture is a pull type -- push the k**b is for water, pull it out to shut it off. What type and what is the name of this on/off water valve fixture? Also, is this typically threaded or a compression type fitting?

Answer 1

It is a push/pull gate valve. As compared to the turn type valves, it is usually either on or off and nothing in between. Turn types come in these gate valve with a quarter turn between on & off. Depending on the dishwasher you purchased the incoming water line will either be a 3/8" or 1/2" NPT fitting.
