Hydraulic valves | Pressure control valve

What are sequence and unloading valves, and for which hydraulic application do you need one?

A change in position of the pressure control valve (i.e. open or closed) occurs either gradually (by control) or suddenly (by switch). Pressure valves with a switching task are referred to as pressure valves with fixed throttle: sequence valves and unloading valves.

Sequence valves are used to direct the flow to a secondary circuit. When the primary hydraulic circuit reaches a preset pressure, flow is permitted to the secondary circuit. Unloading valves are remotely-piloted pressure shut-off valves that direct flow to the tank when the preset pressure in a particular location of the hydraulic circuit has been reached.
