Sectional design lets you get the exact valve components and configuration required for your application. Each section has load checks.
I've got a boom truck that's old electric over hydraulic. I need a six stack valve that will work to hold the loads of each function in the neutral position and also let the oil flow though the valve back to pump as it's a gear pump. I think this is called a tandem valve. I also want the levers to return to the neutral position when let loose. I don't understand all the different teminology.
A: Your description fits how this valve will function if all Double Acting Spring-to Center Cylinder spools are chosen (spool option B). The X in the part number denotes Open Center, or Tandem Center. We sell this particular valve as a quick-order kit under part number 9-7558.
