Looking into needle valves for PP blending, couple of concerns/questions.
After researching Parker and Hoke I see there there are different style tips on the needle (blunt, etc). Is one better than the other for blending?
If one is aquired, do parts need to be changed to be HP O2 compatible? Or is just a cleaning needed? I guess the better question would be do valves like Parker and Hoke already have the proper components in them, or separation of the incompatible components from the HP O2 area of the valve?
Having trouble determining how "slow opening" the different models are, not sure what to look for.
If another needle valve would be dedicated to continuous blending only, how big a concern is the valve design at the low pressure in that scenario?
Maybe some guru here can suggest a make/model?
