  • What have I got here?
  • A friend gave me A HUSCO 3501 Duel control valve. I want to use it to put an angle cylinder(S) on my 8-N Dearborn loader that has a front mounted modern type snow plow on it. I can't find any specs on the valve. Does anyone have any info for it? Thanks in advance.

  • Re: What have I got here?
  • What sort of specifications are you looking for? All you need for the plow angle cylinders is a valve with one double acting cylinder spool. If you can't figure out the old HUSCO valve ditch it. You can buy a brand new compact single spool valve for $40 plus shipping

  • Re: What have I got here?
  • OldHokie, Thanks for the input. Have you got a recommendation for a Dual control Valve for this set up? I need one lever to lift the loader arms and the other to operate the angle cylinder. It would be be easier to re-plumb a dual valve then try to add on another single valve to the system. However if the cost of a dual valve is a lot higher, then that will be a consideration for me too. I've learned from seeing your advice to others on this Forum that your suggestions are always spot on. Your advice several years ago really helped me to re-plumb my loader with filters and a new control valve when my original control valve went belly up.

  • I assume the loader has single acting cylinders on it so if you use a valve with double acting spools you need to plumb the unused port on the loader spool back to the tank. Probably what we discussed before.

    Here is a link to a company that sells an inexpensive line of imported valves. The HCV 2x13 valve in the link should fit the bill and it is on sale right now for a very good price. In fact I have one in the shop right now that a customer purchased for his 8N - made in Bulgaria.

  • Re: What have I got here?
  • Got it, Yes the arms are single acting cylinders. It shouldn't be a problem to plumb the unused port of the valve back to the tank. I assume if I use a double action cylinder on the plow I just use both ports on one side of the valve. One to each side of the cylinder? Thanks for the link. I knew I could count on you for good advice.

  • Re: What have I got here?
  • How you plumb the plow cylinder(s) depends on what you have. Your original post indicated you have some sort of truck plow and I was assuming it already had hydraulic angle on it. This sounds like you are adding it. OEM setups commonly pair two single acting cylinders in opposed positions and use one to angle the blade while retracting the other. Additionally a cushion valve is mounted in the middle of the circuit to protect against damaging the plow and/or plow truck by hitting obstacles. The cushion valve allows the impacted cylinder to retract and the other to extend on extremely hard impacts rather than hold the blade hydraulically locked in a fixed position. I.E - it cushions the impact to prevent damage.

  • Re: What have I got here?
  • Yes, that type of blade is what I have but it has no angle cylinders attached. It is a manual postilion blade. So does adding two cylinders change what Valve you suggested? Does the cushion valve come separately or is it incorporated in another type of Control Valve I need to purchase?

  • Re: What have I got here?
  • The cushion valve is an additional item. You can get one for about $85 and it can be added after the fact if you decide to go without it initially. It has four ports - two are in from the control valve and the other two are out to the cylinders. As you can see in the last picture the cushion valve is mounted to the plow frame and two short hoses run from the OUT ports on the valve to the ports on the cylinder. Nice and neat - stays on the plow when it is dismounted.

    You can use one of the the DA spools on the valve I linked for the plow cylinders. You connect one port to each cylinder (or the IN ports on the cushion valve if you are using one). Typically the plow control valve would have quick connects on the work ports to make it easy to dismount the plow.

  • Re: What have I got here?
  • You are welcome and thanks for the kind words but you give me way too much credit. All I did was a little Google searching for valves and parrot what I learned here about cushion valves from fellow board member Mark (aka mhb@ufe). Now you are in a position to pass it forward 8-)

  • Re: What have I got here?
  • One more question for you. Thanks for your patience with me. If I use a cushion valve can I then use one single dual port cylinder and still be protected from hard impacts?

  • Re: What have I got here?
  • OTTOMH I cannot see why that would not work. The valve will simply bypass to the other side of the DA circuit. It may not be quite as effective since the displacements in the different sections of the cylinder are not equal but it won't be totally locked.

  • A picture of one such setup
  • Here is a picture of how it is commonly done:

  • Re: What have I got here?
  • A visit to the Husco web site might reveal what you need.
    I just replaced the Husco loader valve I had with something else that actually works.
