Piston-type pressure reducing valve: the outlet pressure after pressure reduction is unstable

The piston diameter is 16 mm, the spring is 20 mm long with a wire diameter of 1.1 mm, there are 4 effective turns of the spring, and the inner diameter is 10.2 mm. The inlet pressure is 8 MPa, while the outlet pressure varies between 0.5 and 1.0 MPa. How can the outlet pressure be reduced to around 0.4 MPa?
You are currently using primary pressure regulation; it is recommended to consider secondary pressure regulation, as this will make the pressure more stable
