Hydraulic top link help needed

[S-G-R]

I have a hydraulic top link that I would like to add a check valve to. Would one of these work?

You want a double pilot check valve for your cylinder like the one in the link below. @TheOldHokie can confirm but that's my understanding. The link has some good information on how it works.

Double Pilot Operated Hydraulic Check Valve, #6 SAE Ports, 11 GPM

the double for sure though no real need for 11GPM.
it's a small cylinder,ain't moving far and only for a few seconds.....

That one is a bit rich for me. About $208 Canadian and then duty on top.

I only meant that it's the type of check valve you need, not that you should by that particular one. My apologies for the confusion.

Gotcha, that stuff is out of my area of expertise.
