Different Valve Maintenance Systems Explained


The difference between preventative and reactive maintenance lies in how they approach valve maintenance. Preventive maintenance is meant to avoid problems and prevent them from occurring in the first place. For example, a deteriorated seal will eventually flake and break down, introducing particles into the process. Therefore, a proactive approach is more effective than reactive maintenance because it is preventative.


The ERV-750 valve maintenance system is fully mobile and mounts to flatbed trucks. It comes with a hydro-vac system, a a purpose-built storage body, and the essentials for operating and exercising valves. CUDRC installed the first Valve Maintenance Trailer in April 2013 and is currently evaluating a second. The company is also considering purchasing another VMT-1 Valve Maintenance Trailer.

It uses WAVE technology to ensure the requisite torque and virtually eliminates valve breakage. In addition, it uses advanced software to calculate valve size, position, and turning direction to improve productivity. The powerful machine also stores and uploads data to an online system that allows operators to monitor and track their work. For the maximum efficiency and reduced risk of damage, the Wachs ERV-750 Valve Maintenance System comes with a three-inch square steel tubular arm.


The TM-7(TM) Valve Management System is designed for various valve types and mounted on various flatbed trucks. This system is complete with a hydro-vac system, telescoping valve key, excavating wands, wash-down wands, and all the essentials for exercising and operating valves. It also comes with full training on valve maintenance and valve exercises.

The TM-7 features patented Intelligent Automation, which allows a single operator to exercise stubborn valves without damaging them. It is designed to provide the ultimate valve operator performance with a single drive, torque accepting construction, and adjustable torque. In addition, it has an optional docking station and a a three-year warranty. You’ll love its compact dimensions and powerful torque-absorption capabilities. And its high-quality hydraulics allow for maximum productivity and safety.

With the ERV-750 extended reach valve operator, even the most inexperienced operator can perform valve maintenance tasks successfully. This fully automated system requires no operator effort and has twin arms that reach up to 13′ in 270 degrees. The hydraulic disc brakes, path-of-least resistance, and “no-assumptions” automation technology minimize valve breakage. In addition, the ERV-750’s integrated sensors ensure safe operation and provide vital information about the health of each valve.


The GRAND LX(TM) Valva-Maintenance System features a twin-turner valve maintenance trailer, a class-leading ERV-750 extended-reach operator, and a powerful TM-7 SD Plus swivel valve operator. It also comes with a Kubota 1.1L I-3 4-stroke diesel to power the system’s contained functions. In addition, the GRAND LX includes an HTMA Class-II circuit with a ten-gallon reservoir and a fan-cooled heat exchanger. As a result, it’s a fully-compliant valve maintenance trailer for contractors and municipalities.

It is a trailer-mounted valve exerciser with a three-inch-tall main frame and integrated 8-inch fork-slotted tubes extending the unit’s entire length. This fully automated valve exerciser features a HD TM-7 valve exerciser, an ERV-750 actuating system, and an HC-100 VITALS controller.

This advanced valve exerciser is equipped with patented Intelligent Automation. It can apply up to 2500 ft-lbs of torque and has many mounting options. It’s the ultimate power-operated valve operator, featuring a single drive, patented Intelligent Automation, and torque-accepting construction. And with a three-year warranty, it’s an investment you’ll be happy to make. Once you have installed the GRAND LX(TM) Valve Maintenance System, you’ll never look back.
