Do you know about boiler blowdown?
It’s the process of removing water from a boiler, controlling the water parameters, minimizing scale, and avoiding other problems.
The rotating disc valve was the standard for the steam locomotive boiler blowdown. It was an integral part of the process. Now, it serves other purposes, as well.
However, how does it work? Why is it a crucial part of many industrial processes? Keep on reading to understand how rotating disc valves operate and their benefits.
How Rotating Disc Valves Operate
No other types of disc valves work similarly to how rotating technology operates. It starts with the actuator, which moves the stem and lever arm. Their movement drives the disc.
Throughout the process, the disc remains in contact with the seat or pad. The coiled springs cause it to move vertically, which allows it to compensate for thermal expansion and contraction. This design also helps overcome backpressure.
When the disc rotates on its seat, it shears and wipes away any accumulated process material. It prevents particles from lodging between the surfaces.
Benefits Of A Rotating Disc Valve
The Everlasting Valve Company has almost perfected the rotating-disc-valve technology. But, what makes it unique? Read on to find out how it can benefit you.
For Abrasive Material
Rotating valves specifically handle abrasive and erosive material, cycling heavy slurries without sticking. The shearing discs cut through solids, allowing for self-cleaning features.
The valves can handle scale, chemicals, boiler blowdown, and flashing condensate. They’re also suitable for processes with high pressure or temperature.
Long-Lasting
You regularly face issues like clogging and erosion with other disc valve options. Those problems are what the rotating technology solves.
Particulates are the primary cause of clogging of other designs. The disc and lever arm chop and churn these out with rotating valves. The result is little to no material that can clog up your machine.
As mentioned above, the rotating action also shears away any accumulated material. It spreads wear and tears evenly, leading to no erosion issues like in the other valves.
Less Maintenance
Maintenance is easy because of the flat seating surfaces and simple parts. The repairable seat allows for reduced expenses, too.
Versatility
The design’s simplicity makes for enhanced versatility. A rotating disc valve has minimal parts, which means it’s adaptable to any needs, as well.
Tight Seal
The manufacturing process produces a secure seal for the shutoff and isolation parts. Machine lapping with several light bands of flatness assures a tight fastening, while sealing improves with constant use of the valves.
Get A Rotating Disc Valve
The rotating disc valve technology benefits industrial processes no other valve can replicate. However, it’s worth learning more about them first before you commit.
Research more on how rotating valves work or ask for a demonstration. Don’t hesitate to contact the manufacturer if you have any questions.
