The springs in spring-loaded safety valves designed for different pressures must be replaced.
Generally, a PN16 spring-loaded safety valve should be equipped with five springs.
The pressure ranges are specified as follows: 0 MPa to 0.3 MPa; 0.3 MPa to 0.6 MPa; 0.6 MPa to 0.9 MPa; 0.9 MPa to 1.2 MPa; 1.2 MPa to 1.6 MPa.
