Selection of back pressure valve
We have many basic technologies that we need when selecting valves, so we need to pay attention to the following four points when selecting back pressure valves:
1. There are 12 types of pipeline diameters: DN6, 8, 10, 15, 20, 25, 32, 40, 50, 65, 80, and 100.
2. There are two series of inlet pressure, 0.3MPa and 1.0MPa, and the pressure difference between the inlet and outlet can be adjusted by adjusting the length of the spring.
3. The materials are PVC (P), SS304/316 stainless steel (S), carbon steel (A)
4. The inlet and outlet connection methods provide three options: internal thread, flange and hose joint.
The above four points are the things we need to pay attention to when selecting the back pressure valve. After reading the above content carefully, I believe it will bring you great help when selecting the back pressure valve.
