Help with top link

[Stomper]

The check valve just prevents it from drifting but wont stop gravity from acting faster than the pump when the thing is cycled. The check valve also prevents it from ever being used with float

I doubt that you will find a double pilot operated check valve that will go onto your cylinder like the typical off-the-shelf top link units have as pictured in post #4. Those take 3/8" British pipe thread and your ports are most likely #6 oring boss.
I recommend putting .031 orifice fittings on each port and your issue should be resolved.

I will start there. Thanks

Any chance you sell them?

Both actually.

The orifice fittings are only in #6 oring boss-M/#6 JIC-M in straight or 45s or 90s.

The check valve for 3/8 British ports, #6 oring boss ports, and I have adaptors for #8 oring boss ports which raises the check valve higher off the cylinder ports.
The fittings that I have for the check valve are all for a #6 JIC hose connection.

I'm guessing you need something?

I'm thinking that I need the orifice fitting to slow my top link down and help fight gravity. The OP here seems to have problems similar to what I've had, he just knows enough about hydraulic to actually put it into words.

I recommend that both ports have the orifice fittings. I know that just 1 on the rod end is supposed to do the job, but too many times in the past it has taken 2 to do the job right. So 2 it is from me each and every time.

Now I build the orifice into the actual port adaptor fittings so that no additional fittings are used that create additional connection points as well as taking up more room. But what I have may not work for your application.
