control valve are:

❑ Pressure regulator valve which is used to prevent pressure fluctuation in the circuit and control the

❑ Pressure limiting valve or pressure relief valve to ensure the inlet pressure below a certain
pressure and

❑ Pressure sequence valve which generates control signal when the valve reaches a certain
pressure limit..
