Product Details (Woods BH65)
There's a "load check valve" between the control valve working ports for every DA cylinder's ports, can't you just follow the hoses from the port pair adjacent to each LCV to see which cylinder / function it serves (i.e. trace the hoses to see the control valve port assignments) or even easier just see what moves when you actuate the lever on each section of the control valve and look at the LCV aligned with that lever?
Noting that these LCV's only serve to prevent cylinder drop while the spools are
intentionally actuated in the brief transition between pressuring one port and pressurizing the other for a given cylinder - they are not to be confused with "load
hold valves" which, if you have them, would be external to the control valve and serve to prevent cylinder drop over time absent any intentional control valve actuation (or the neutral position leakage rate spec'd for the control valve).
IF you have the latter, they should be obvious as a fitting or 'block' between the control valve and the cylinder they "hold" .... again easily determined by just following the route of the hose to the cylinder (and function) they serve to "hold".
If I'm missing something in your question, please accept my apology and perhaps try restatement to explain more clearly what you're looking for and/or the problem you're trying to address?
