Valve Maintenance Systems

Valve Maintenance Trailers


The GRAND LX with the optional ERV-750 and TM-7 onboard is the industry standard for a completely upgradable, versatile platform designed to transport all the valve maintenance and vacuum tools needed in the field. Built for years of reliable service, it’s the perfect solution for municipalities or contractors looking for a rugged, long lasting self-contained system.

Valve Exerciser Options
Most clients choose to equip their GRAND LX with the versatile ERV-750.
This combination allows a single operator to easily reach and turn most valves from the curbside, using the Intelligent Automation.

Many municipalities with big or older, stubborn valves will specify adding our TM-7 heavy duty exerciser. Cranking out up to an incredible 2500 ft-lbs of torque (3390 Nm), it’s compatible with the Intelligent Automation, Recon controller and VITALS software. Equipped with VITALS, the TM-7 will apply the minimum force needed, and trigger auto reverse or auto shut down to virtually eliminate valve breakage.

Every GRAND LX is constructed with:

  • Fully welded high strength steel box section frame
  • Dexter torsion axle rated @ 7000 lbs GVWR
  • Choice of ball or pintle hitch
  • Bulldog super duty platform jack stand (extendable by hand crank)
  • Painted steel road wheels and heavy duty tires

Completely Customizable
Designed to carry the ERV-750 and TM-7, the configuration that will work best for a client can be specified. Completely customizable, it’s built for the long haul and can be upgraded later as budgets allow.

Standard equipment on the GRAND LX includes a 27 horsepower gasoline or 29 horsepower diesel driven power supply, a powerful Utility Vac for cleaning out vaults and meter boxes, a high pressure Water

Jet system for additional vault cleaning and light excavation, a 250L water tank and a power tilting 946L spoils tank.

When ERV-750 equipped, the combination of Intelligent Automation, VITALS Mobile software and Recon controller offers unparalleled productivity, even for an inexperienced operator.

Valve Maintenance Trucks


Prior to the ERV-750 extended reach valve turning systems were fragile and could not develop the necessary torque to free stuck valves. The ERV-750 offers an easier, safer and more productive alternative – true hands free operation with Intelligent Automation. Extended Reach Valve turning and maintenance systems have been perfected with this model.

It allows a single operator to quickly and easily reach and turn any valve from 6” to 60” (DN150-1500), including inaccessible and obstructed valve boxes. With a 3.96m reach, it will apply up to 750 ft-lbs of torque (1015 Nm) in a graduated sequence, using patented Intelligent Automation.

The design offers flexibility without compromises, and far greater effective power.
The articulated ERV-750 arm is simply placed near the valve, the telescoping or jointed keyway inserted, and the valve is remotely and safely exercised using our handheld Recon controller.
The ERV-750 does not require the operator to physically hold it down on the valve.

For powering a pickup truck mounted ERV-750, the HPU-750 or a PTO are used.

There are four configurations to choose from:

  • Customer installed front bumper mount, where the entire truck bed is free for use.
  • Pedestal Mount, most space efficient of bed mounts, unit stows lengthwise along the bed sidewall
  • Bed Carriage Mount, allows unit to slide and store totally inside the bed. Its low profile design allows the use of a cap
  • Hitch Mount, entire truck bed is free for use.


  • Patented Intelligent Automation: With Intelligent Automation, only the minimum amount of torque necessary is applied, virtually eliminating valve breakage. It’s fully automated, so even inexperienced operators can quickly and safely free stuck and neglected valves. Using the industry leading VITALS software, users can obtain critical information on valve health, such as valve type, open/close status, turn direction and torque requirements. All of this information is easily logged, uploaded, stored and synchronized.
  • Truck or Trailer Mounting: The ERV-750 offers a wide range of trailer or truck mounting options. Trailers are self-contained with the power supply on board, while truck mounting can use a PTO for power. The ERV-750 is built to last a lifetime.


The TM-7 is ideal for valves that are old, corroded and resist turning by ordinary exercisers.
Using it with the patented Intelligent Automation, it can apply up to a massive 2500 ft-lbs (3390 Nm) of torque. With a large variety of truck and trailer mounting options to choose from, the TM-7 is the ultimate in power operated valve operators.

Tough but Smart
At its maximum torque output the TM-7 could easily break most valves, but the Intelligent Automation monitors torque gently applies the minimum force required in a gradual sequence. Equipped with a Recon handheld controller and VITALS software, the TM-7 will remotely exercise the valve, capture the data and activate auto reverse and auto shut down as needed, eliminating potential valve breakage completely.

Our Recon GPS handheld controller allows the user to stand clear of the keyway for safety. The operator can monitor the turning sequence on the VITALS Mobile screen in real time, while the Recon captures the information to synchronize with your water management system.

Designed for Stubborn Valves
Using a TM-7 to safely implement AWWA valve exercising procedures on large valves is easy, even for an inexperienced operator, as the TM-7 fully conforms to the AWWA Valve Exercising Standard.
Available with truck and trailer mounting options, the TM-7 is self-contained, modular and will fit almost any vehicle or trailer. Mounting a TM-7 to our GRAND LX Trailer offers a huge range of motion, for unparalleled productivity.
Designed for stubborn valves, even ones you may already have scheduled for replacement, if it’s not broken the TM-7 will likely turn it.
