Where is the critical point for viscosity when selecting valves?
Thread Content
Are there any empirical data indicating at what viscosity level – generally, in terms of both dynamic and kinematic viscosity – it is more appropriate to start using eccentric rotary valves or V-ball valves?
What is your viscosity? I remember that dirt can also be dealt with using eccentricity.
There are values of 55 and also 77; both represent dynamic viscosity, with the unit being mm2/s
It doesn’t seem like anything has been decided yet! But generally, viscosity is taken into consideration; as for how much, I don’t know! !
