Help: Operating pressure of Q41F-64P valve at 150°C
Thread Content
As the title suggests, what is the operating pressure of the Q41F-64P valve at 150°C? Is this pressure value the same for all manufacturers? According to the **standards, what should it be?
Remember, there is a curve chart on the valve sample
GB/T 12237-2007 Steel ball valves for use in the petroleum, petrochemical, and related industries Table 1 PTFE seat: ≤DN50: 2.24 MPa; DN50–DN100: 1.54 MPa; >DN100: 0.61 MPa. RPTFE seat: ≤DN50: 2.83 MPa; DN50–DN100: 1.84 MPa; >DN100: 0.72 MPa
I don’t know much about valves; what do these terms mean? Our valve has a diameter of DN150; what is the operating pressure?
Standard PTFE valve seat: 0.61 MPa; Enhanced RPTFE valve seat: 0.72 MPa. It depends on the specific type of material used
Rubber-sealed valves at this temperature aren’t very durable, are they?
The F valve seat is at a too high temperature for this condition
It is recommended to use PPL or PEEK valve seat rings
