The AVT EZ Valve® 4" to 14" (100mm to 350mm) is the most popular range of EZ Valves.

Ideal for use in a range of locations and applications such as municipal water networks, transmission and distribution lines, wastewater treatments plants, sewer force mains, high-rise buildings, and refining and petrochemical plants.

The AVT EZ Valve 4" to 14" is an inline insertion valve that can be installed on water lines and depending on the pipe material, installation takes anywhere from 45 minutes for our smaller valves to 3 hours for our larger range.

The valve uses an integral isolation gate, which when operated after the slot has been milled into the pipe, allows the EM machine to be removed and the resilient wedge installed. This process means the valve can be installed on a live line while the water is flowing. The resilient wedge needs to be lowered just 2/3 of the way into the pipe to commission the install meaning users have the choice of when to turn off their water.

The AVT EZ Valve 4" to 14" installs on an active line, so there is no need to turn off the water flow. This means fixing a line is fast, with fewer disruptions to businesses and residents and less cost and risk for owners and operators.

Ranked among the industry’s most innovative solutions, the light and compact AVT EZ Valve is designed with a built-in isolation gate that allows the valve to be installed under pressure, a design feature that permits flow through the line while the repair is being made. It is durable, reliable, and certified to industry standards.
