Sliding Face Seal
Sliding Face Seal
(OP)
I'm working on designing a rotary valve that is essentially one cylinder inside another. The inner cylinder rotates to align ports on both the inboard end of the cylinder and on the outer diameter of the cylinder. I know I've seen valves built like this before, so I was wondering if anyone had any tips on how to design the face seals that will go at the inboard end of the inner cylinder. Do I use o-rings or custom molded Viton washers around the ports? If I use o-rings, how much of a concern is there with the edge of the o-ring trying to stand-up out of the gland and getting caught on the edge of the opposing port? Thanks!

What pressure?
How fast and how often does the valve change position?

Better consult with a patent service before you spend a lot of resources.
Neles just introduced a control valve with the rotary cage within the last few months.
