Electric Actuated Resilient Seated Butterfly Valve

The electric actuated resilient seated butterfly valve is an intelligent and efficient fluid control device,widely applied in industrial,municipal,and commercial pipeline systems that require automatic or remote control.As a key variant of the resilient seated butterfly valve,it is characterized by its integrated electric actuator,which replaces manual operation with motor-driven control,realizing precise,labor-saving,and automated fluid regulation,making it ideal for large pipelines,high-control-frequency scenarios,and harsh operating environments.

The core structure of this valve consists of a robust valve body,a concentric rotating disc,a central stem,a high-performance resilient sealing seat,and an electric actuator.The valve body is typically made of cast iron,cast steel,or stainless steel,ensuring excellent structural rigidity,corrosion resistance,and durability to withstand diverse medium conditions and pressure impacts.The resilient seat,crafted from premium elastomers such as EPDM,NBR,or Viton,boasts superior elasticity,wear resistance,and aging resistance,achieving bubble-tight shut-off when the valve is closed and effectively preventing medium leakage.

The electric actuator is the core component that distinguishes this valve from manual or pneumatic types.It is equipped with a high-efficiency motor,gearbox,and control module,enabling automatic 90-degree rotation of the disc to open or close the valve.The actuator supports two control modes:on-off control(for simple opening and closing)and modulating control(for precise flow regulation),with adjustable torque and stroke to meet different control requirements.It also features overload protection,position feedback,and fault alarm functions,ensuring safe and reliable operation,and can be remotely controlled through a control system for convenient operation and monitoring.

This valve is compatible with wafer,lug,and flanged connection modes,suitable for pipelines with nominal diameters from DN50 to DN1500,and works stably under low to medium pressure conditions(PN10-PN25).Installation is convenient,and daily maintenance mainly involves checking the actuator’s power supply,lubricating the stem and gearbox,and inspecting the sealing performance.It is widely used in water supply and drainage,sewage treatment,petrochemical,power generation,HVAC,and fire protection systems,suitable for controlling clean water,sewage,mild corrosive liquids,and low-pressure gases.

In summary,the electric actuated resilient seated butterfly valve integrates automated control,precise regulation,reliable sealing,and strong adaptability.It effectively reduces manual labor intensity,improves control efficiency,and is an indispensable intelligent fluid control solution for modern pipeline systems,providing stable and efficient support for industrial and municipal operations.
