baat karte hain process piping ke aik aur ahem rotary motion valve ki. Jise Plug Valve kaha jata hai. Iska technical short code VR hai. Yeh valve system mein tight isolation aur high sealing efficiency ke liye install kiya jata hai. Iski pehli specification iska Closure Member hai. Is valve ke andar cylindrical ya tapered shape ka plug hota hai. Yeh plug valve body ki cavity ke andar rotate karta hai. Doosra technical feature iski Sealing Efficiency hai. Plug ka surface area ball valve ke muqably mein kafi bada hota hai. Is badi surface area ki wajah se yeh valve tight aur behtreen shut-off faraham karta hai. Iska teesra sab se bada advantage Slurry Service hai. Yeh valve sludge, solids, aur viscous fluids ke liye behtreen perform karta hai. Aise gande aur gaarhe fluids mein yeh ball valve se bhi zyada kamyab rehta hai. Fitters ke liye technical point yeh hai, ke is valve ki maintenance ke doran plug aur body cavity ki seat par scratch nahi aana chahiye. Agar iski seat damage ho jaye, to iska tight shut-off fail ho jata hai. Aur line mein passing ka khatra barh jata hai.
