Here is a New Diamond valve bock to run a v plow with dual acting cylinders. Information on these is almost impposible to find. These were used with both under hood electric pumps and belt drive pumps from the engine. This replaced the old cable operated valve body. Diamond stoped using V plow and these blocks in the summer of 1989. The blocks have been on the shelf for a long time the block has been discontinued for around 15 years it makes a great convertion if you have a pump. These work great for a V plow with Dual acting culinders. Or you can use this on a skid steer this has 6 ports the in and out and then 4 for your dual acting cylinders. Let me knosw if you have any questions.
