Industry make use of valves to begin, control and stop the flow a range of fluid compositions. Chemical plants use them to pour acidic and flammable solutions; oil sands use them for bitumen, agricultural industries need them for mixtures. Slurry valves make for an essential part of optimizing processes. Dual Valves have been offering for the best slurry pumps for decades that have increased production and uptimes. A right slurry valve can do wonders for optimization, but a wrong valve can mean continuous maintenance and slow production.
But even the best slurry valve will become useless in harsh conditions and seasons. Therefore, it is imperative to maintain the valves for efficient production says www.mining-technology.com/contractors/pumps/giw-industries/pressreleases/prepare-pumps-cold-winter-weather/. It is also vital to use the right valve for the proper system. Here is a breakdown of 3 industries and the kind of slurry valves they require.
• Power Plants
A power industry makes use of ash, high temperature and slurries of limestone and gypsum. This means that the valves they need are not used in any other conditions. To control the ash flow in power plants, the valve should have a hardened gate material. A ceramic overlay is essential. These valves also require particular features like chest liners. A chest liner ensures there is no ash buildup in the valve. Another requirement of power plant slurry valves is the ability to endure high temperatures like 400F. Therefore, they require unique sealing materials like Aflas.
• Chemical Engineering
A chemical engineering plant could be in a food industry or a pharmaceutical firm or even a hazardous material disposal firm. The core need for any chemical facility would be the specialty valves. Using conventional valves would lead to continuous changing of the part resulting in lower production time. A simple example would be slurry valves that carry titanium dioxide. This substance is used in paints and is the liquid version of sandpaper. Titanium dioxide is like sharply jagged cubes.
Now, think of this flowing in slurry inside a non-customized valve. It would abrade the valve regularly and need frequent replacement. To better production time a slurry valve with Inconel gates would be the best option. Similarly, a paper processing plant would need valves that have replaceable seats and flush ports. The reason being to make clean paper fiber contaminations need to be removed. These could be in the form of staples or wires. Using a valve that has been made for another function would be eroded quickly and not last long in the cleaning process.
• Mining Plants
A mining plant transport slurry that cause a lot of abrasion due to stones, coarse sand, and clumped clay. Furthermore, most substances, like bitumen, are very dense. Therefore, to transport them from point A to point B requires extreme pressure and temperature. This means a valve used in such industry would need to withstand the erosion and heat. A knife gate valve is one such slurry valve. With sharp blades to cut through the dense material, the valves can better the uptime. Coating of tungsten carbide can make the slurry valves resistant to abrasion and ensure quicker production.
