Selection of steam pipeline valves
Thread Content
The design pressure of the steam pipeline is 3.9 MPa, the design temperature is 460 degrees, and the pipe diameter is DN150. What kilogram rating should the manual valve for this pipeline have, and what type of valve should be used?

Choose a gate valve; the pressure should be 4.2 MPa. If you’re not confident, go with 6.4 MPa
For PN64 DN150, choose a globe valve when high isolation requirements exist; choose a gate valve when such requirements are not high
I think it’s best to use a valve body weighing 64 kilograms!
Use PN64 DN150 stop valve
Pn 63 Plunger Globe Valve
