Flange Butterfly ValveIt Is A Butterfly Valve That Adopts Flange Connection Method. Its Core Function Is To Control The Flow Of Pipeline Fluid. With The Firmness Of Flange Connection And The Small Flow Resistance Advantage Of Butterfly Valve, It Is Widely Used In Medium And High Pressure Pipeline Systems Such As Fire Protection, Water Supply And Drainage, Petrochemical, And Industry. It Is A Core Control Valve That Balances Sealing And Practicality.

Structurally, It Mainly Consists Of A Valve Body, Butterfly Plate, Control Mechanism (handle Or Turbine), Flange Interface, And Sealing Components. The Valve Body Is Mostly Made Of Ductile Iron And Stainless Steel Materials, Suitable For Various Media Working Conditions. The Core Highlight Is The Flange Connection Design. The Valve Body Comes With Flange Plates At Both Ends, Which Are Precisely Connected To The Pipeline Flange Through Bolts, Ensuring Reliable Sealing And Vibration Resistance. It Is Suitable For Large-diameter, Medium High Pressure Working Conditions. The Valve Stem Is Rigidly Connected To The Butterfly Plate, And Can Be Fully Opened Or Closed By Rotating 90 °. The Structure Is Compact And The Installation Is Standardized.

The Core Features Are Distinct, With Stable And Sealed Flange Connections, Suitable For Media With Nominal Pressures Of 1.0~6.4MPa And ≤ 120 ℃, Which Can Effectively Prevent Fluid Leakage And Facilitate Installation, Disassembly, And Maintenance; Low Flow Resistance, When Fully Opened, The Butterfly Plate Is Flush With The Inner Wall Of The Pipeline, Reducing Transportation Energy Consumption; Excellent Sealing Performance, Divided Into Soft Seals (rubber, Polytetrafluoroethylene) And Hard Seals, With Small Leakage And Suitable For Different Sealing Requirements; Flexible Control, Can Be Paired With A Handle Or Turbine Transmission, Easy Maintenance, Low Failure Rate, Can Be Installed Horizontally Or Vertically, And Suitable For Various Pipe Diameters.

Widely Applicable In Various Scenarios, Including Municipal Water Supply And Drainage Main Pipes, Fire-fighting High-pressure Pipelines, Petrochemical Medium Transportation, Industrial Circulating Water Pipelines, Etc., Especially Suitable For Large-diameter, Medium And High-pressure Pipeline Scenarios With High Requirements For Connection Firmness And Sealing. Compared To Clamp Type Butterfly Valves, It Has A More Stable Connection, Stronger Pressure Bearing Capacity, And Easier Maintenance, Making It A Widely Used Control Valve In Various Medium And High Pressure, Large-diameter Pipeline Systems.
