Manufacturing Excellence Since 1931
It’s officially the holiday season! No matter how you choose to celebrate, we’d like to wish our partners, distributors, customers, and fellow Dwyer team members safe and happy holidays. Continue reading “Happy Holidays from the Dwyer Family”
Maintaining efficiency in wet chemical scrubbers has become one of the most important missions of current APC facilities due to urban growth and plant expansion/modernization projects as good stewards of the community. Systems often run above the 90% efficiency mark with the help of accurate make-up water control instruments. Continue reading “Sump Level Make-Up Water Controls in Wet Chemical Scrubbers”
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?”
As industries such as building automation and water/wastewater become more energy-efficient, powder and bulk is also increasing energy efficiency using pressure transmitters and variable frequency drives. Pressure transmitter demand is also growing due to more stringent regulations in hazardous environments, where remote control and specialty housings must be available.
With a typical dust collection system, a pressure sensor (such as our Series A3000 or Series DHII) can measure differential pressure across filter bags. The sensor then sends a switched signal to a timer board (such as the Series DCT500A or DCT1000) to signal a filter cleaning. Pressure in the system is created by a blower, typically positioned near the filter banks on top of the hopper. The system can also use a level switch (like our Series PLS and Series CLS2) to signal a full hopper and possibly open a valve to empty the hopper. So how do pressure transmitters reduce energy consumption? And how can you prevent an explosion in a hazardous environment without the additional cost of specialty enclosures?

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. Continue reading “Product Highlight: Hi-Flow™ Control Valves”
