Gate valves are essential components in pipeline systems, used to control the flow of fluid by opening or closing a gate mechanism. Among the various types of gate valves available, the two most common are the ওএস&Y (বাইরে স্ক্রু এবং জোয়াল) gate valve and the এনআরএস (Non-Rising Stem) গেট ভালভ. While both valves serve the same purpose, they differ significantly in their design, নির্মাণ, and application. এই অনুচ্ছেদে, we will explore the differences between OS&Y and NRS gate valves in detail.
Automated production will eventually eliminate manpower, as is the case with valves, and other production industries. We will eventually free our hands.
This is actually a good thing in the long run, and there may be worker unemployment in the short term. But in the long run, efficient production capacity will lead to higher social output and building capacity. Thus allowing everyone to be more productive with less work.

One-way valves also called ভালভ পরীক্ষা or non-return valves. It is a valve where the fluid can only flow along the inlet and the medium at the outlet cannot flow back.
It use in hydraulic systems to prevent the reverse flow of oil, or in pneumatic systems to prevent the reverse flow of compressed air. They play a crucial role in various industries by ensuring the unidirectional flow of substances in pipelines, systems, and equipment, thereby enhancing safety, efficiency, and performance.
According to the global industrial statistics of developed countries, the gross product of valves is the sum of compressors, fans and pumps, accounting for about 5% of the output value of the entire machinery industry. একই সময়ে, as … বিস্তারিত পড়ুন
