The Motorized Sector Gate is a high-efficiency,automated industrial shut-off and regulating valve,also known as an electric fan gate valve.It is specifically designed for large ventilation ducts,flue gas pipelines,dust removal systems,and material conveying pipelines,integrating electric drive,precise control,and reliable sealing to meet the needs of intelligent industrial operation.

1.Core Structure&Components

-Valve Body:Adopts heavy-duty design,made of carbon steel,ductile iron,or stainless steel(customizable according to working conditions).The inner cavity is streamlined to reduce flow resistance,and the overall structure is compact to save installation space,suitable for large-diameter pipeline installation.

-Sector Gate:Precision-machined fan-shaped(sector)structure,with smooth surface and wear-resistant coating.The gate is connected to the rotating shaft,ensuring stable rotation without jamming,and its shape is perfectly matched with the valve seat to achieve tight sealing.

-Electric Actuator:Equipped with high-torque electric actuator(AC/DC optional),with overload protection,stroke limit,and manual emergency operation functions.It can realize precise control of the gate opening and closing,and support remote control and system linkage,adapting to intelligent control systems.

-Sealing System:Adopts high-temperature resistant,wear-resistant soft seals(silicone,FKM)or metal-to-metal seals,ensuring tight shut-off and preventing leakage of air,flue gas,dust,or materials.The seal is detachable and replaceable,facilitating maintenance.

-Control Panel:Equipped with a local control panel,which can realize on-site opening,closing,and position adjustment;it can also be connected to the central control system to realize remote monitoring and automatic control,with fault alarm function for easy operation and maintenance.

2.Working Principle

The Motorized Sector Gate is driven by an electric actuator:when the actuator receives a control signal,it drives the rotating shaft to rotate,and the fan-shaped gate connected to the rotating shaft rotates accordingly.When fully closed,the gate fits tightly with the valve seat,blocking the flow channel and achieving complete shut-off of media(air,flue gas,dust,etc.).When fully open,the gate rotates to be parallel to the flow direction,forming an unobstructed flow passage with minimal resistance.The electric actuator can precisely control the opening degree of the gate,realizing stepless regulation of flow,and the stroke limit function ensures that the gate does not overtravel,protecting the valve and pipeline.

3.Key Features

-Automated&Precise Control:Electric actuator realizes automatic opening,closing,and flow regulation,with high control precision and stable performance,reducing manual operation intensity.

-Low Flow Resistance:Streamlined valve body and fan-shaped gate design minimize flow resistance,reducing energy consumption of the supporting system(such as fans,pumps).

-Stable&Durable:Heavy-duty structure,high-quality materials,and wear-resistant coating ensure long service life,suitable for long-term continuous operation in harsh environments.

-Tight Sealing:Advanced sealing structure effectively prevents media leakage,avoiding environmental pollution and energy waste.

-Easy Operation&Maintenance:Local+remote dual control mode,with fault alarm and manual emergency operation functions;detachable seals and accessible components facilitate daily inspection and maintenance.

-Strong Adaptability:High-temperature,dust-proof,and anti-corrosion design,suitable for various harsh working conditions such as high temperature,heavy dust,and corrosive media.

4.Applications
