Hi,
Necessary data for the design of on-off valve I think is below :
Max Shut-off Pressure
Design Pressure
Design Temperature
Piping Material Spec
Connected Line Size (valve size shall be same as line size)
Valve Type
Additional Process Data (Toxic, Acid, Containing Solid, etc.)
On the contrary, unnecessary data for the design of on-off valve I think is below :
Density
Specific Heat Ratid (Cp/Cv)
Viscosity
Operating Pressure
Operating Temperature
Flow Rate
Compressibility Factor, Z
Molecular Weight
etc.
I think fluid properties are not required to design on-off valves, but if they are needed, tell me some codes or standards like ISA 75.01.
I want to know how that property applies.
Thank you.
