Mounted valves

SmithCo works hand in hand with customers to make sure we’re giving them the right trailer for their needs. As part of the process, there are a number of choices that customers need to make to ensure their side dump trailer is the best possible fit for the job. This article series explains what customers should take into consideration when specing their trailer. See the series here.

Once our experts have collaborated with a customer to choose the right side dump trailer and tub style, the next step in the process of specing their trailer is determining the best placement of the hydraulic control valve. There are two options for customers: a truck-mounted valve, or a trailer-mounted valve. Consider the pros and cons below to think through the right choice for your situation.

Truck-Mounted Hydraulic Control ValveTrailer-Mounted Hydraulic Control Valve
  • Less expensive
  • Decreases troubleshooting time if there is a problem, since the only place you’ll need to investigate is the truck
  • Compatible with trucks that already have a wet kit and pull other hydraulically operated trailers; requires minimal changes to truck

  • Less flexible for situations where your truck pulls more than one hydraulically operated trailer
  • When troubleshooting, you may need to look at truck wiring, trailer wiring, or the air supply before locating the issue
  • Somewhat more expensive than mounting the valve on the truck

Your neighbor’s hydraulic valve placement may not be the one for you

Interestingly, we see regional trends in where our customers opt to place the hydraulic control valve. But we always work closely with customers to make sure they know both options, and that just because they’ve seen side dumps with one installation doesn’t mean that’s the best choice for their situation. It’s also reassuring to know the location of the valve can of course be adapted in the future if an operator’s situation changes.
