RAYS Triple Offset Metal Seated Butterfly Valve

Triple Offset Metal Seated Butterfly ValveTriple Offset Butterfly Seated Valves are a type of high-performance butterfly valve, also known as triple eccentric metal-seated butterfly valves. These valves are designed with a triple offset structure that provides tight sealing characteristics, making them excellent for high-pressure and high-temperature applications. Technical ParametersProduct Type: Triple Offset Metal Seated Butterfly ValveSize Range: DN50-DN1200 or 2″-48″Pressure Rating: From 150LB to 2500LBOperating Temperature: From -196C to 650CConnection Type:RF, BW, LUG,WaferMaterial: Carbon steel (such as WCB), stainless steel (such as CF8/CF8M), alloys (such as Monel), duplex steel, etc.Suitable Medium:Butterfly Valves are designed to control fluid types such as water, oil, gas, steam, etcOperation Mode: Handle, turbine, gas-hydraulic linkage, electric, pneumatic, electro-hydraulic linkage, etc Product FeaturesGood sealing performance: Due to their eccentric design, when the valve is closed, the disc can tightly fit against the seat, achieving metal-to-metal sealing and minimizing leakage.High temperature and pressure tolerance: Metal sealing components enable triple offset butterfly valves to withstand higher temperatures and pressures, making them more durable than ordinary rubber or PTFE sealed butterfly valves.Longevity and low maintenance costs: Reduced friction means less wear and tear, leading to an extended service life and lower maintenance costs. The three “offsets” implication:First offset: The disc is offset from the shaft axis, which allows for reduced friction between the disc and the seal during opening.Second offset: The shaft axis is offset from the pipe centerline, which further reduces friction and wear between the sealing surfaces.Third offset: The centerline of the sealing surface is offset, often with the disc sealing surface and seat sealing surface being conical. This conical configuration allows for a tighter seal upon closure. Because of these characteristics, triple offset butterfly valves are very popular in critical processes within industries such as oil and gas, chemical, heating, and water treatment.…
