Applications

Fire Hydrants

Across the US alone there are nearly 9 million* fire hydrants, many of which are not operational due to their need for repair.

 

In many cases repairs to these vital resources are postponed time and time again as shutting off their water supply would lead to local businesses and homes, also losing their water supply. This leaves water districts and municipalities with the delicate balancing act of ensuring enough hydrants are in operation, should they be needed, while not disrupting their communities to carry out repairs.

 

Typically fire hydrants are supplied by a ‘T’ line. This is a small section of water line that is fed by the main line running along a street. Conventional water valves require a large section of pipe to be available when installed due to the need for at least two excavations for the fitting of line stops and a valve, but the AVT EZ Valve, an insertion valve, requires just one small excavation meaning they can be fit on this small ‘T’ line and isolate the hydrant without having any effect on the rest of the local water supply.

Municipalities and water companies must regularly exercsie the valves on their networks

Valve Exercise Programs

Municipalities and water companies have the responsibility of regularly exercising the valves on their networks to ensure they are operable. Valves are a vital piece of equipment when it comes to maintaining and repairing water systems, and in an emergency can be called upon to isolate a specific section of pipe enabling repairs and reducing the number of residences and businesses affected by the need to shut off the water flow.

If valves are not regularly exercised, or closed and opened, they can seize up making them inoperable. In this situation, the AVT EZ Valve, an insertion valve, can be fitting onto a live water main, close to the existing inoperable valve, or anywhere necessary to create a control point where required.

Many municipalities now have EZ Valves on hand to install should they find an inoperable valve on their network.

The AVT EZ Valve, an insertion valve, can be used within a range of applications across many industries such as oil refineries and water utility networks.
Control points create smaller areas of isolation should a valve need to be closed

Addition of Control Points

Many water networks are decades old and when originally created, were not designed to handle the new infrastructure that was added over the years.

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. These points enable water network operators to isolate small areas should they need to repair burst mains or carry out routine maintenance. 

The AVT EZ Valve, an insertion valve, is proving to be the valve of choice when it comes to creating these new control points as it can be installed with just one excavation being made, on a relatively short section of pipe and without the need to shut off the water supply.
