In a hydraulic circuit, a hydraulic pressure regulator opens and bypasses fluid when pressure exceeds its setting. The valve then closes again when pressure falls. The valve acts as a pressure relief valve and can bypass fluid anytime without intervention.

How does a hydraulic pressure reducer work?

A pressure-reducing valve maintains lower pressures in branches of hydraulic systems. … A pressure-reducing valve is normally an open, 2-way valve that allows system pressure fluid to flow through it until a set pressure is reached downstream. It then shifts to throttle flow into the branch.

How is hydraulic pressure regulated?

Pressure control is achieved in hydraulic systems by metering the flow of a fluid into or out of a constrained volume. Pressure control is achieved in hydraulic systems by metering the flow of a fluid into or out of a constrained volume. Relief valves and pressure-reducing valves are not pressure controllers.
