| High Light | Zero Leakage Double Eccentric Butterfly Valve ，Double Eccentric Butterfly Valve 220V ，380V Double Offset Butterfly Valve | ||
Our Hydropower Butterfly Valve is specially engineered as core flow control and isolation equipment for hydropower stations, turbine inlet systems, reservoir dams, water diversion pipelines, and hydraulic engineering projects. Adopting advanced double-eccentric/triple-eccentric structure design, it integrates functions of cut-off, throttling, emergency shutdown, and pressure regulation.
With compact layout, low flow resistance, ultra-tight sealing, and stable operation, it perfectly adapts to high-flow, high-pressure, and complex water quality working conditions in hydropower industries, serving as the preferred solution for hydropower pipeline safety control.
Valve body adopts high-strength ductile iron QT450-10, cast steel WCB, or stainless steel. The streamlined butterfly disc is integrally cast with optimized fluid design, effectively avoiding water flow flutter and deformation under high velocity.
The whole body is treated with epoxy anti-corrosion coating, resisting erosion from clean water, sediment-laden water, and seawater, adapting to long-term outdoor and underground harsh working environments.
Optional soft seal (EPDM/NBR rubber) and metal hard seal solutions: soft seal achieves zero leakage (ANSI Class VI) for conventional hydropower systems; metal hard seal suits high-temperature and high-pressure working conditions, with wear resistance and long service life.
Eccentric structure reduces friction between seal and seat ring, lowering opening/closing torque and extending sealing lifespan.
The main shaft is made of stainless alloy steel, featuring high toughness, anti-rust, and anti-fatigue performance. Precision bearing and self-lubricating bushing design ensure flexible rotation, no jamming, and minimal maintenance.
| Applicable Medium | Clean water, sediment-laden water, seawater and other non-corrosive water media |
|---|---|
| Medium Temperature | ≤80℃ |
| Pressure Class | PN2.5 / PN6 / PN10 / PN16 / PN25 / PN40 |
| Driving Voltage | AC220V/380V, DC24V/110V/220V |
| Protection Grade | IP67, suitable for outdoor and humid working conditions |
| Sealing Standard | Soft seal zero leakage; metal seal low leakage, compliant with international hydropower valve standards |
Widely applied in hydropower station turbine inlet/outlet pipelines, reservoir sluice control, water conservancy diversion projects, municipal water supply and drainage, pump station systems, and large-scale hydraulic engineering.
It undertakes flow regulation, pipeline isolation, emergency cut-off, and overpressure protection tasks, ensuring safe and stable operation of the entire hydropower system.
We support customized design on structure, material, driving mode, and size according to project requirements. Strictly implemented ISO and national industry standards in production, with complete quality inspection system, stable product quality, and long service life.
Provide one-stop services including product selection, technical solution design, on-site installation guidance, and after-sales maintenance.
