Applications

Insertion Valve Solutions for Mechanical Contractors

Mechanical contractors who are responsible for the heating or cooling systems, refrigeration, piping, HVAC, and plumbing of a building regularly need to install valves on in-situ water lines. The AVT EZ Valve is installed without shutting off the water and is the ideal option for this application.

Fire Hydrants and how Insertion Valves aid repair

In many cases repairs to fire hydrants are postponed as shutting off their water supply would lead to local businesses and homes also losing their water supply. This leaves authorities with the balancing act of ensuring hydrants are operational, while not disrupting their communities.

Fire hydrant
Industrial and Mechanical Solutions

Refineries, tank farms, process plants, and many other industrial and mechanical operations require a constant supply of running water. If a break or leak occurs or a piece of equipment fed by water, such as booster pumps, require repair or maintenance, many times, operations must be halted.

Addition of Control Points

Many water networks are decades old and when originally created, were not designed to handle the new infrastructure. This issue affects thousands of communities around the world and in many cases, water companies choose to insert new valves to create control points around their networks.
