Flange Slow Closing Check ValveIt Is An Automatic Check Valve That Adopts Flange Connection And Has A Slow Closing Function. Its Core Function Is To Prevent Fluid Backflow In The Pipeline, Slow Down The Closing Speed Of The Valve Disc Through A Slow Closing Structure, Eliminate Opening And Closing Noise And Water Hammer Impact. With The Firmness Of Flange Connection And The Advantages Of Slow Closing Protection, It Is Widely Used In Medium And High Pressure Pipeline Systems Such As Water Supply And Drainage, Fire Protection, And Industry. It Is The Core Protective Valve To Ensure The Safety Of Pipelines And Equipment.

Structurally, It Mainly Consists Of A Valve Body, Valve Disc, Slow Closing Device, Flange Interface, Guiding Mechanism, And Sealing Components. The Valve Body Is Mostly Made Of Cast Steel, Stainless Steel, And Other Materials, Which Are Corrosion-resistant And High-pressure Resistant. The Core Highlight Is The Flange Connection And Slow Closing Structure: The Flange Interface Can Be Precisely Connected To The Pipeline Flange Through Bolts, With Reliable Sealing, Anti Vibration, And Suitable For Large-diameter And High-pressure Working Conditions; Built In Hydraulic Slow Closing Or Spring Slow Closing Components, No Manual Operation Required, Relying On Fluid Pressure Difference To Automatically Open And Close. When Reverse Fluid Flows, The Slow Closing Device Controls The Valve Disc To Slowly Close, Avoiding Impact Damage.

The Core Features Are Distinct, With Stable And Sealed Flange Connections, Suitable For Medium And High Pressure (1.0~4.0MPa), Large-diameter Pipelines, And Easy Installation And Disassembly For Maintenance; The Buffering Effect Is Outstanding, Which Can Effectively Buffer The Impact Of Water Hammer, Eliminate The Noise Of Opening And Closing, And Protect The Water Pump And Pipeline From Damage; Excellent Sealing Performance, With A Tight Fit Between The Valve Disc And Seat, Achieving Zero Leakage; Temperature And Pressure Resistance, Adaptable To Various Fluid Media, Low Flow Resistance, Good Energy Saving, Compact Structure, Can Be Installed Horizontally Or Vertically, Easy Maintenance, And Low Failure Rate.

Widely Applicable Scenarios, Mainly Used For Fire Pump Outlets, Municipal Water Supply And Drainage Main Pipes, Industrial Circulating Water Pipelines, Petrochemical Medium Transportation Pipelines, Etc., Especially Suitable For High-pressure, Large-diameter Pipeline Scenarios With High Requirements For Waterproof Hammers And Backflow Prevention. Compared To Ordinary Check Valves, Its Flange Connection Adaptability Is Stronger, The Slow Closing Function Is More Protective, And It Can Effectively Extend The Service Life Of Pipeline Equipment. It Is An Indispensable Protective Check Valve In High-pressure Pipeline Systems.
