What are the valves' lifecycle costs? How to choose the best-quality gate valve? Hawle answers your most frequently asked questions about valves and fittings.

The keys to choosing a gate valve [Part 1 of 2]

Compromising on quality when purchasing gate valves commonly leads to early replacement when the gate valve inevitably fails.  This two-part guide will help you to recognize what makes a quality product stand out among the many gate valve options on the market. Part 1 covers pre-purchase quality checks, valve body & coating checks, and checks related to the wedge, wedge nut, and wedge guides

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.

The hidden costs of gate valves

Gate valves may seem like a suitable area to reduce costs for water utilities, but the total lifecycle costs of low-grade gate valves can be more than you think... 
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.
Fittings

How to choose a fitting? [A Hawle guide to pipe connections]

Pipe fittings are a perfect solution for providing connections for pipelines. Additionally, they can modify pipeline systems by extending the run or altering the pipe flow direction. Various pipe fittings exist for different applications and industries, including water supply, pharmaceuticals, power generation, petrochemicals, pulp & paper, and others. Pipe fittings for water supply come in multiple materials, types, shapes, and sizes. Choosing the suitable pipe fitting is crucial to ensure the rigidity of the plumbing system. An incorrect pipe fitting can lead to flow restrictions, leakages, and additional costs.
