“Based on the pressure rating, valves can be classified as follows according to their nominal pressure: 1. Vacuum valves: absolute pressure

Based on nominal pressure, 1.6 and 2.5 MPa are two adjacent pressure grades; there are no other nominal pressures in between. For example, within the range of PN2.5–6.4 MPa, there is also a value of 4.0, and within the range of PN10.0–80.0 MPa, there is a value of 20.0, and so on
