Product Introduction:
Flange triple eccentric metal seated butterfly valve adopts triple offset wedge metal hard sealing structure.
The valve body comes with integral flanges for bolt connection with pipelines.
The disc rotates 0°~90° for fluid shut-off and flow regulation.No friction between sealing surfaces during opening and closing.
It achieves bi-directional tight shutoff, with outstanding performance of high temperature resistance, high pressure resistance, abrasion resistance and fire safety.
Flange connection provides stable installation. Widely used in power plants, district heating, petrochemical, metallurgy for steam, thermal oil, flue gas, fuel gas and high-temperature fluid pipelines.
Main Features:
1.Triple Offset Metal Hard Seal.
Three offset geometry ensures instant separation between disc and seat when opening without scraping.
Wedge self-tightening sealing realizes bi-directional bubble-tight shutoff.
Stainless steel laminated metal seal keeps stable performance under high temperature.
2.Integral Flange Connection
Direct bolt connection with pipeline flanges. Firm and safe.
The valve will not fall off when pipelines are disassembled, suitable for vibrating pipelines and high-risk working sites.
3.Multiple Actuator Options
D343H: Worm gear handwheel operation with position indicator.
D643H: Pneumatic actuator (double acting / spring return), support on-off or modulating control.
D943H: Electric actuator for remote automatic control, equipped with manual override.
4.Diversified Material Selection
WCB carbon steel, 304, 316 stainless steel optional for different media and temperature.
