Butterfly Check ValveIt Is An Automatic Check Valve That Uses A Clamp Connection And A Butterfly Plate As The Opening And Closing Element. Its Core Function Is To Prevent Fluid Backflow In The Pipeline. With The Convenience Of Clamp Connection And The Flow Resistance Advantage Of Butterfly Structure, It Is Widely Used In Medium And Low Pressure Pipeline Systems Such As Water Supply And Drainage, Fire Protection, HVAC, Etc. It Is A Basic Protective Valve That Balances Installation Efficiency And Protective Performance.

Structurally, It Mainly Consists Of A Valve Body, Butterfly Plate, Valve Seat, Shaft, And Sealing Components. The Valve Body Adopts A Thin Design, Mostly Made Of Ductile Iron Or Stainless Steel Materials, Which Are Corrosion-resistant And Lightweight In Structure. The Core Highlight Is The Clamp Connection Design, Which Eliminates The Need For Flanges And Directly Clamps The Valve Between Two Pipeline Flanges Using Bolts. It Is Easy To Install And Disassemble, Greatly Saving Installation Space And Costs; As An Opening And Closing Component, The Butterfly Plate Is Connected To The Valve Body Through A Rotating Shaft, Without The Need For Manual Operation. It Automatically Opens And Closes By Relying On The Fluid Pressure Difference. When The Forward Water Flow Pushes Open The Butterfly Plate, It Automatically Resets And Fits The Valve Seat When The Reverse Water Flow Occurs, Blocking Backflow.

The Core Features Are Distinct, With Compact And Lightweight Clamp Connections, Suitable For Medium And Low Pressure (0.6~1.6MPa), Various Pipe Diameters, High Installation Efficiency, And Saving Pipeline Space; The Butterfly Structure Has Extremely Low Flow Resistance, And When Fully Opened, The Butterfly Plate Is Flush With The Inner Wall Of The Pipeline, Reducing Transportation Energy Consumption; Excellent Sealing Performance, The Valve Seat Is Made Of Rubber Or Polytetrafluoroethylene Material, And The Butterfly Plate Is Tightly Attached To The Valve Seat, Achieving Zero Leakage; Quick Opening And Closing Response, Capable Of Effectively Buffering Minor Water Hammer Impacts, Simple Structure, No Complex Moving Parts, Easy Maintenance, Low Failure Rate, And Can Be Installed Horizontally Or Vertically.

Widely Applicable Scenarios, Mainly Used For Municipal Water Supply And Drainage Pipelines, Fire Protection Pipelines, HVAC Systems, Industrial Circulating Water Pipelines, Etc., Especially Suitable For Medium And Low Voltage Scenarios With Small Space And Convenient Installation Requirements, Such As High-rise Building Water Supply And Drainage Pipelines, Small Factory Circulating Water Pipelines, Etc. Compared To Flange Type Check Valves, It Has A Smaller Volume, More Efficient Installation, Lower Cost, And Is Suitable For Medium And Low Pressure Conditions. It Is An Ideal Check Valve That Balances Practicality And Economy.
