Gate valve

Gate valve

The keys to choosing a gate valve [Part 2 of 2]

Part 1 of this guide covered using standards compliance, materials selection, high-quality processing, and design value as indicators of valve quality and ultimately of the gate valve’s long term performance. The final part of this guide expands on those principles as they relate to the spindle and the seals of the gate valve, then delivers a brief summary of all the checks outlined in this guide so far.

non revenue water (NRW)

How to repair water main leaks

As mentioned in our previous article, real losses, or leakages, represent a substantial part of non-revenue water. Of course, every water supply network experiences some real losses. There is a minimum amount of water loss even in newly commissioned distribution systems, also called an unavoidable minimum. However, those losses should always remain within economic limits.
