ESCRIPTION
The ERV-750 is an automated, medium-duty valve operator
mounted on an extension arm to reach valves up to 13 feet
from the pedestal mount. With the ERV-750 mounted on
your truck or utility trailer, you can reach many valves when
parked curbside. It operates on hydraulic power, using a
ruggedized, computer-based controller that can store and
transfer valve operation data.
The standard configuration is provided on a Wachs Swivel-
Vac
heavy-duty trailer; the system’s components can also be
mounted on a truck or pickup bed with the optional installa-
tion kit.
