This is a three-lever mechanical operator used to remotely actuate valves or linkages on commercial vehicles, most commonly cargo tank trailers with multiple compartments.
Confirm the part fits before you buy. Applications and interchange numbers are researched and audited per part.
We don't publish fitment for this part yet. Rather than guess, get it confirmed against your truck in under a minute.
The operator translates hand-lever movement into mechanical push/pull cable motion, allowing the driver to open, close, or divert product flow without climbing onto the trailer. It is typically replaced when internal bushings wear, linkages bind, or cable attachment points become sloppy, causing imprecise valve control.
