Pilot-operated pressure relief valve
A pressure relief valve that consists of two direct operated relief valves in series, an extremely small orifice, and a drain passage that passes through the center of the balanced spool. This is something you definitely have to see to understand.
This exquisite, fully-functional cutaway makes it possible for students to see in 3D exactly how a pilot- operated pressure relief valve functions.
