chapter 9: relief and unloading pressure controls

in a hydraulic circuit a relief valve opens and bypasses fluid when pressure exceeds its setting. the valve then closes again when pressure falls. this means a relief valve can bypass fluid anytime . . . or all the time . . . without intervention by maintenance. it also means the system can run hot even with a heat exchanger installed.inquire now
