Since the holidays are a time of reminiscing, let’s take a look back at the most popular articles read on EmpoweringValves.com this year! Don’t be afraid to use the comments section to request valve topics you’d like to see covered in 2018.

Why You Should Size Check Valves

Most check valves are selected by size and class to match the size and class of the pipe. This article looks to examine the consequences of selecting check valves the way most currently are and offers a different method of selection, why it can lead to far higher and longer performance and the supporting formulas and fluid dynamics that one can use to prove it yourself.

To Coat Valves or Not to Coat Valves… That is the Question!

Are you thinking about coating your valves? There are several options available – fusion bonded epoxy, liquid epoxy, thermoplastic, hard-coating, hard-facing – each of these is explained along with their “pros” and “cons”.

The Use of Thermal Spray Coatings for Metal Seated Valves

In the case of metal to metal sealing surfaces, coatings are designed to protect against wear due to galling of the sealing surfaces and coatings protect from corrosive, erosive and abrasive wear caused by the product flowing through them.

Finding the Right Severe Service Valve for LNG Applications

Shutdowns for valve maintenance or replacement are costly to plant capacity, and ultimately revenue. In this article, we will look at an application solution along with valve design to address challenges faced in process industries.

Valve Coatings Reference Chart

It’s no secret that the use of coatings in valves extends service life and helps improve operational efficiency as part of the pumping system, especially when used in conjunction with pump coatings. The issue, however, is that not all coatings are created equal – so the correct identification and specification of a coating based on system operating conditions is critical to its success. Download this Valve Coating Reference Guide to help you identify which coating should be specified for your specific valve operating conditions.

Repair or Replace? Considerations for Managing Aging Equipment

Plant systems and equipment cannot last forever, especially as new technology and regulations demand more from them. Some plants have increased their capacity and operating pressures which puts a strain on aging equipment, especially in the case of sensitive components like safety relief valves and rupture discs. It can be difficult to know when to continue maintaining or repairing aging equipment or when to replace.

Sealing and Containment Devices That Can Reduce Emissions and Increase Profitability

The role of sealing devices in reducing methane emissions has been a hot topic in our industry for some time, and we see that trend is continuing. Sealing and containment devices are an integral part of efforts to minimize emissions of volatile organic compounds (VOCs). Plants, refineries and other facilities have an increased incentive to ensure that valves and other rotating equipment operate to emissions-compliant levels.

How Do Check Valves Function, And Why Would They Be Selected Over Other Valve Types?

Also known as non-return, one-way, and clack valves, check valves are different from other types of valves in their ability to pass fluid in solely one direction. This sort of function is essential for a variety of safety applications, as well as for preventing overflow. With each industry needing different fluids and/or gases transported over different landscapes, lengths, and at different temperatures, check valves come in several designs and can have a various advantages.

What Is A Plug Valve And When Is It Used?

A plug valve is shaped like a cylinder or cone and can be rotated inside the valve body to control flow of fluids. Although there are many types of plug valves, there are four general categories, each with their own advantages.

Gasket Selection and Installation

Gaskets come in many shapes and sizes and are generally used to create a seal between two or more stationary parts of a mechanical assembly. In most cases, gasket selection and installation is done based upon temperature of the media, desired pressure, and the compatibility of the gasket material with the media as well as the application.
