Hello, Need some help identifying the pictured remote valve. It is on my Ford 850. It has FOMOCO cast into it but no part numbers except on the handles. The part numbers are for the handles. I think I have a handle on how it works, but I cannot find any information on it at all. i.e. model number, documentation etc. Went to the New Holland dealer and they had nothing. It appears to me to be a dual action valve, ie in and out. One side is split on the output using one port. One side is plumbed for in and out using both ports. It has a float adjustment knob in the front. Not sure what its purpose is. Any help would be appreciated.
