A Dwyer Guide to the Digital Catalog

In this age of virtual meetings and online connections, to “Google” something has become synonymous with quickly looking up information. For some, bookshelves are more for decor than they are functional, and trends are leading to becoming more environmentally-friendly and saving paper. Print media is not necessarily “dead,” but it is becoming much less prevalent as we journey forward in this digital age.

When speaking on digital resources, we have to take this chance to talk about some of the benefits that our digital catalog can offer. Available on both desktop (via our website) and mobile (via the app), the digital catalog allows you instantaneous access to application guides, selection guides, and product specifications.  Continue reading “A Dwyer Guide to the Digital Catalog”

Why Choose a 38R Self-Acting Control Valve?

There are several reasons why a 38R is a great choice in your heating or cooling applications, with the most obvious being that there is no power required. The 38R temperature regulator is a fully self-contained unit, requiring no external power source. This could mean substantial savings over the operation of other types of valves.

Regulation takes place when the sensing bulb  is exposed to changes in temperature. The thermal system is charged with a predetermined amount of vapor fill, which, when heated, will cause a bellows within the unit’s actuator housing to expand. As the bellows expands, it compresses a return spring while simultaneously moving the valve stem downward to stroke the valve.
When the process temperature decreases or in the event of thermal system failure, the return spring will move the valve stem upward to the “out” position. Continue reading “Why Choose a 38R Self-Acting Control Valve?”

Product Highlight: Hi-Flow™ Control Valves

Hi-Flow™ Control Valve

Hi-Flow™ control valves are single seated, top or cage guided globe valves – probably the simplest, from a construction standpoint, yet most versatile control valve in use. The Hi-Flow™ valve can fit applications with a smaller size valve since the valve has a greater flow capacity than most conventional valves of the same size. Coupled with a high flow capacity, the Hi-Flow™ valve maintains a wide rangeability of 50:1 to ensure precise control.

Certificates of Calibration Explained

Dwyer Instruments, Inc. offers a variety of calibration services for new or previously purchased products. In 2019, the Dwyer Instruments, Inc. – Engineering Laboratory, located in Michigan City, IN, gained accreditation to ISO/IEC 17025:2017 through the ANSI National Accreditation Board. The Dwyer lab now offers two different types of calibration certificates for our products: a certificate of NIST calibration and an ISO/IEC 17025:2017 accredited certificate of calibration. Now that accredited calibration services are available for select Dwyer products, it is important to know the differences between these two different calibration certificates. Knowing these differences will allow you to understand which calibration certificate will best suit your needs. Continue reading “Certificates of Calibration Explained”
