Here’s Your Guide To The Right Slurry Valve!

Operating time is a vital factor which affects the profit of various companies which has slurries involved in their processes. Slurry valves are real saviors which optimize the operating time of the processes. But, you can enjoy the benefits only if you select the right slurry valve. A wrong choice may not be effective in reducing the operation time. They may also require increased maintenance and cause less production. Check out the reviews of some Slurry Samplers here.
All slurry valves are not created equal, so you must be careful while selecting valves!

According to, slurry valves should be chosen depending upon the type of application. Here are some valve applications! Let us see the types of slurry valves required for each type!

Fertilizer processing for agriculture
Fertilizer production for agriculture is an area which is prone to scale build-up, hot-acid flushing, etc. Fertilizers like Diammonium phosphate is produced from marine fossils. During the process, scale gets continuously deposited on the valves and walls of the pipes thereby restricting the slurry flow. To remove the blocks, they have to be flushed with hot acid once in a few weeks. So valves which can work even in heavy scaling and which can withstand the hot acid should be chosen for these applications.

Power plants
Extremely high heat, gypsum and limestone slurries, unique and hot ash, chloride-rich fluids are all specialties of the power industry. In addition to this, those power plants where coal is burnt, require special methods for the removal of ash from exhaust gases. Dense as well as powdery ash needs to be separated from the gas before their release to the atmosphere. Following are the features required for valves that are used in ash flow process in power plants.
· Gate materials should be hard
· Chest liners which prevent buildup of ash in the chest area
· High temperature withstanding seal material (for example, Aflas)

Hydrocarbon engineering and mining
Excessive wearing down and severe pressure is what the valves used in mining and hydrocarbon industry should go through. Valves which are used in the bitumen extraction process has to deal with slurries including big stones and also clay and sand. Moreover, its long distance transportation needs high pressure and high temperature which the valves should be able to withstand.

Knife gate valves which have sharp blades to penetrate the gummy bitumen are the commonly used valves here. The material used in the valve is often stainless steel with tungsten carbide coats to enhance their life. Abrasion resistant push-through valves which are non-discharging are required in concentrator plants which deal with the mining of expensive metals.

Chemical engineering
Chemical engineering is a very broad field including diverse applications such as food processing, pharmaceuticals, treatment of unhealthy chemicals, etc. Hence the valve requirements in this field are also very broad. Highly abrasive titanium dioxide transport requires customized valves which are replaceable. Similarly, in paper processing application hardened valves with easily changeable seats are a must.

Conclusively, choose the slurry valves depending on your application and its special requirements and ensure that the production goals are met!
