Hydraulic Flashcards Quizlet

If the primary port of this type pressure valve were connected to a system pressure, and the secondary port were connected to the tank, the flow from the pump could be directed back to tank when pressure applied by the pump becomes excessive. A normally non-passing pressure valve used in this manner is called a relief valve.

Unloading Valves LunchBox Sessions

Unloading valves are very similar to pilot operated, balanced relief valves. The only difference is where the pilot pressure comes from. In unloading valves when external pressure is applied to Port X that is greater than the pilot setting, the pilot poppet will crack open, allowing the main poppet to open.
