Pressure rating of the valve
Thread Content
In the samples of high-pressure gate valves from TYCO in the United States, the following information is provided: Technical data – Sizes: 5” – 24”; ASME standards: B16.34 – 1996. The overall length of the valves is specified according to ASME B16.10 – 1992. Pressure classes: 1000, 1690, 1715, 2260, 2500, 2850. What’s unclear is that these pressure classes such as 1000, 1690, and 1715 are unfamiliar to me; could someone with expertise explain what these mean? ?
For restricted or special grades, the values can be calculated using the insertion method; what we usually encounter are standard pressure grades such as CL150LB/300LB/600LB/900LB/1500LB/2500LB/4500LB, which are specified in ASME B16.34.

Then why isn’t 1500 in that book?
The maximum amount in our company is 1500. So, what are 2500 and 4500 used for?
2500 is used in high-pressure steam pipelines!
4500 is roughly equivalent to a pressure level slightly higher than the national standard of 420…… It is generally used in boilers, steam turbines – in short, in any application related to electricity·····
LS is incorrect, right? CL4500LB corresponds to 77.6 MPa, while CL2500LB corresponds to 42 MPa. CL4500LB is generally used in power plants for ultra-supercritical applications.
