TheHydraulic Fan Gate Valve is a heavy-duty,high-performance industrial shut-off and regulating valve,specifically engineered for large-scale ventilation,dust removal,flue gas,and air duct systems.Also commonly referred to as hydraulic fan damper or hydraulic sector gate valve,it relies on a hydraulic drive system to deliver stable,reliable operation in harsh industrial environments with high temperature,heavy dust,and corrosive flue gas.

1.Core Structure&Components

-Valve Body:Made of high-strength carbon steel,ductile iron,or stainless steel(customizable for corrosion resistance),with a compact,heavy-duty design to withstand high pressure and temperature fluctuations.The body is integrated with a streamlined flow channel to minimize wind resistance.

-Fan-Shaped Gate:Adopts a sector(fan-like)structure,precision-machined for tight fitting;the gate surface is treated with anti-wear,high-temperature resistant coating to enhance durability and extend service life.The fan shape ensures smooth opening and closing without jamming.

-Hydraulic Drive System:Equipped with a professional hydraulic station,hydraulic cylinder,and control valve group.It provides stable lifting force,realizing slow start and slow stop to avoid impact and vibration on the pipeline system during operation,protecting the valve and pipeline from damage.

-Sealing System:Adopts high-temperature resistant,wear-resistant soft seals(silicone,fluorine rubber)or metal-to-metal seals,ensuring tight shut-off and preventing air,flue gas,or dust leakage.Seals are replaceable for easy maintenance.

-Control System:Supports three control modes—manual,electric,and system linkage.It can be equipped with a remote control module to realize automatic switching,monitoring,and fault alarm,adapting to intelligent industrial control needs.

2.Working Principle

The Hydraulic Fan Gate Valve operates based on hydraulic transmission:the hydraulic station provides stable hydraulic pressure to drive the hydraulic cylinder,which in turn drives the fan-shaped gate to rotate or lift(depending on the installation type)along the rotating shaft.When fully closed,the fan gate fits tightly with the valve seat,blocking the flow channel and achieving complete shut-off of air,flue gas,or dust.When fully open,the gate rotates to be parallel to the flow direction,forming an unobstructed flow passage with minimal wind resistance.The hydraulic drive ensures smooth,uniform movement,avoiding the impact caused by rapid opening and closing,and ensuring stable operation of the entire pipeline system.

3.Key Features

-Stable&Reliable Operation:Hydraulic drive provides strong,stable power,with slow start/stop function to reduce pipeline impact and vibration.

-Low Wind Resistance:Streamlined flow channel and fan-shaped gate design minimize air resistance,reducing energy consumption of fans and ventilation systems.

-High Temperature&Wear Resistance:High-quality materials and surface treatment enable the valve to work stably in environments with temperatures up to 400℃(customizable for higher temperatures)and resist wear from dust and particles.

-Tight Sealing:Advanced sealing structure ensures zero leakage,effectively preventing the escape of flue gas,dust,or harmful gases.

-Easy Maintenance:Simple structure,replaceable seals,and accessible hydraulic components make daily inspection and maintenance convenient,reducing downtime.

-Strong Adaptability:Dust-proof,anti-corrosion design,suitable for harsh working conditions in metallurgy,cement,power,and chemical industries.

4.Applications

The Hydraulic Fan Gate Valve is widely used in large-scale industrial pipeline systems that require shut-off,regulation,and switching of air flow,flue gas,or dust,including:

-Metallurgical industry:Blast furnace ventilation,flue gas treatment,and dust removal systems.
