The Electric Hydraulic Sector Gate is an integrated high-performance industrial valve that combines electric control and hydraulic drive,also known as electro-hydraulic fan gate valve.It is specially designed for large-diameter ventilation ducts,flue gas pipelines,dust removal systems,and material conveying pipelines,integrating precise control,stable operation,and reliable sealing to meet the intelligent and heavy-duty operation needs of modern industry.

This valve adopts a scientific and robust structural design.The valve body is made of high-strength carbon steel,ductile iron,or stainless steel,with a streamlined inner cavity that minimizes flow resistance and reduces energy consumption of supporting equipment such as fans.The core component is the precision-machined sector gate,whose surface is treated with anti-wear and anti-corrosion coating,ensuring smooth rotation without jamming and tight fitting with the valve seat to achieve reliable sealing.

The electric hydraulic drive system is the core advantage of this valve,consisting of an electric control unit,hydraulic station,and hydraulic cylinder.The electric control unit realizes automatic control,remote operation,and stroke adjustment,while the hydraulic station provides stable and strong driving force,enabling the gate to start and stop slowly.This design effectively avoids impact and vibration on the pipeline system during operation,protecting the valve and pipeline from damage.In addition,the system is equipped with overload protection and manual emergency operation functions,ensuring safe and stable operation even in abnormal situations.

The sealing system of the Electric Hydraulic Sector Gate adopts high-temperature resistant,wear-resistant soft seals(silicone,FKM)or metal-to-metal seals,realizing bidirectional tight shut-off and preventing leakage of air,flue gas,dust,or materials.The seals are detachable and replaceable,which simplifies daily maintenance and extends the service life of the valve.The valve also features a compact structure,convenient installation,and strong adaptability,able to work stably in harsh environments with high temperature,heavy dust,and corrosive media.

Widely used in metallurgy,cement,thermal power,chemical,environmental protection,and mining industries,this valve is an essential equipment for pipeline shut-off,flow regulation,and flow switching.It is suitable for blast furnace ventilation,kiln flue gas treatment,boiler dust removal,industrial waste gas discharge,and bulk material conveying systems,providing reliable guarantee for the stable and efficient operation of industrial production.

In terms of technical parameters,the valve’s operating temperature ranges from-20℃to 400℃,operating pressure up to PN1.6 MPa,and connection methods include flanged and wafer types,which can be customized according to actual working conditions.Its design and manufacturing comply with relevant international and national standards,ensuring product quality and interchangeability.
