Ask about the types and properties of ball valve seat materials
Thread Content
I hope experts can tell me about the various materials used for valve seats in commonly used ball valves, as well as their operating conditions and characteristics
This is selected based on operating conditions – what specific operating conditions?
Normally, we use PTFE, CPTFE, RPTFE, and PPL. I would like to know what materials are used in special operating conditions such as temperatures below -60°C, or above 200°C, or in other particular situations.
The valve does not have to be a ball valve; there are other options available. Every type of valve has its specific range of applications, and it cannot be generalized. For example, most low-temperature liquid valves use globe valves due to the structural limitations of ball valves.
Temperature is just one of the operating conditions; in addition to temperature, there should also be pressure and the properties of the medium.
LCB, CF8, F316, and so on
You need to choose the model based on your actual operating temperature and medium
TMF4215\TFM1600\PTFE\PPL\PEEK\modified with carbon fiber, modified with glass fiber, modified with metal powder. . . It depends on the working medium you have; it is necessary
:lol:lol Please don’t mislead people, okay?
Nonsense; even hard-sealed valve seats don’t use castings
