“BUTTERFLY VALVE” is a hydro-mechanical device to isolate/control the flow medium in both directions & also typically used to regulate a fluid. In a robust construction of double flanged body one Stainless steel seat ring is fitted in the flow path. A robust circular disc is positioned in the centre of the body. The disc is mounted on two hub stub shaft which is swing through both end body housing. A resilient/stainless steel seat ring moves inside the disc & one disc seat retainer is placed to retain it. A Gear/hand lever operated drive shaft. At the time of sealing action the contracting seating surface effect the sealing and ensuring leak proof sealing. In full open position it facilitate low interrupted reduce bore flow path resulting minor / low headloss.
