Identify functions of the P, T, and X ports for an unloading valve Describe operation of this high-low pumping circuit making use of an unloading valve. Assume pump A is high flow/low pressure and pump B is low flow/high pressure. Assume set value of unloading valve is half that of the main pressure relief valve.

5/20 · The unloading valve is similar to a relief valve, but there's a check valve on the pilot line. Learn why in this quick Live Schematic screencast.Head over to

To add an unloading valve function to a cartridge valve, a special cover is required. The symbol and cutaway view in Figure 11-12 show the setup for an unloading valve that could be used for a hi-lo pump circuit. Chapter 9 provides a complete explanation of unloading valves. Fig. 11-12. 1:1 poppet-type slip-in cartridge valve as an unloading valve
