Introduction
In this article we will approach our selection and review from a different view point. All valves will fail at some point in time, either due to mechanical failure or poor quality system water. Some valves are more durable than others. There are however some valves that are repairable using a tool on the live system. It is these valves we will focus on, as well as combined with general reliability. We will also talk about market leaders, new innovative valves and overall best valves in our opinion going forward.
