Import Flanged Concentric Disc Butterfly Valve — Buy in Bulk from Supplier in China

The flanged concentric disc butterfly valve from Luoyang Jinerjian Trading Co., Ltd. is a mid-line flow control device with a concentric disc design that aligns with the pipe centerline to reduce turbulence and pressure drop. It features a flanged end connection compatible with ANSI B16.5 Class 150 and Class 300 standards, with body materials typically cast iron or ductile iron, and disc materials including stainless steel 304 or 316 depending on fluid compatibility. The valve operates with a quarter-turn mechanism and is rated for pressures up to 16 bar and temperatures from -10°C to 120°C, suitable for water, oil, and compressed air systems.

Typical seat materials are EPDM or NBR rubber, providing a bubble-tight shut-off under low to moderate pressure. The stem is often made of stainless steel with a rising or non-rising design, and the valve may include a worm gear operator for larger sizes. In industrial applications, this valve type is preferred over gate or globe valves where space is limited and frequent cycling is required. The design avoids eccentricity, reducing seat wear and enabling consistent sealing performance across the full disc rotation.

This valve is commonly purchased by contractors in water treatment plants, HVAC installations, and chemical processing facilities that require reliable isolation with minimal maintenance. Buyers typically order in quantities of 10 to 50 units, with packaging in cartons or wooden crates for sea freight. Trade terms are commonly FOB Shanghai or CIF to major ports, with lead times averaging 25 to 40 days after order confirmation. Custom material upgrades or actuator integration can be requested but require direct supplier confirmation.
