Pressure-limiting
valves are a type of pressure control valve.
They safeguard the system against excessive system pressure or limit the operation pressure. Pre-load valves, also called sequence valves are a type of pressure control valve.

function:
The pressure sequence valve (sequence valve) is reversed once the pilot pressure has been reached at port 12, and switched to the initial position via return spring after the signal has been removed. The pressure of the control signal is infinitely adjustable by means of a pressure adjustment screw.

A pressure regulator is a valve that controls the pressure of a fluid or gas to a desired value, using negative feedback from the controlled pressure

Pressure regulators are valves that automatically cut off the flow of a gas or liquid when it is at a certain pressure. Regulators are also used to allow high-pressure fluid supply tanks or lines to be reduced to a usable and safe pressure for different applications.
