Butterfly Valve HandleIt Is A Butterfly Valve That Is Directly Controlled By A Manual Handle. Its Core Function Is To Control The Flow Of Pipeline Fluid. With The Advantages Of Simple Structure, Convenient Operation, And Low Flow Resistance, It Is Widely Used In Medium And Low Pressure Pipeline Systems Such As Fire Protection, Water Supply And Drainage, Industry, HVAC, Etc. It Is A Basic Control Valve That Balances Practicality And Economy.

Structurally, It Mainly Consists Of A Valve Body, Butterfly Plate, Handle Control Mechanism, And Sealing Components. The Valve Body Is Mostly Made Of Ductile Iron And Stainless Steel Materials, Suitable For Various Working Conditions Such As Water, Air, And Ordinary Industrial Media. The Core Highlight Is The Direct Transmission Of The Manual Handle, Which Is Rigidly Connected To The Valve Stem Without The Need For A Worm Gear Reduction Structure. The Operation Is Direct And Efficient, And The Valve Can Be Quickly Fully Opened Or Closed By Rotating The Handle 90 °. The Compact Structure And Small Size Save Installation Space.

The Core Features Are Distinct, With Convenient And Intuitive Operation, Direct Manual Control, No Need For Complex Transmission Mechanisms, Suitable For Small-diameter Valves, And Moderate Operating Force; Simple Structure, Economical Cost, No Redundant Components, Easy Maintenance, Low Failure Rate; Low Flow Resistance, When Fully Opened, The Butterfly Plate Is Flush With The Inner Wall Of The Pipeline, Reducing Transportation Energy Consumption; The Sealing Performance Is Reliable, And The Butterfly Plate Is Tightly Attached To The Valve Seat. There Are Two Types Of Seals: Soft Seal And Hard Seal, With Small Leakage. It Is Suitable For Media With A Nominal Pressure Of 1.0~1.6MPa And ≤ 80 ℃, And Can Be Installed Horizontally Or Vertically.

Widely Applicable Scenarios, Mainly Used For Small Caliber Medium And Low Pressure Pipeline Systems, Such As Building Water Supply And Drainage Branch Pipes, Small Fire Protection Pipelines, Industrial Circulating Water Branch Pipes, HVAC Pipelines, Etc., Suitable For Manual Control, Situations With Certain Requirements For On-off Speed And Simple Working Conditions. Compared To Turbine Butterfly Valves, It Has A Simpler Structure, Lower Cost, And More Direct Operation, Making It One Of The Widely Used Manual Control Butterfly Valves In Small-diameter Pipelines.
