Product Description

Product Overview: Stainless Steel Triple Eccentric Butterfly Valve

The Stainless Steel Triple Eccentric Metal Seated Wafer Butterfly Valve is an advanced fluid control solution designed for high-temperature and demanding pipeline systems. Featuring a sophisticated triple offset structure, this valve minimizes friction between the disc and the sealing ring during operation. This innovative design not only ensures a reliable, tight seal but also significantly extends the service life of the internal components.

Equipped with a heavy-duty worm gear operator, it provides precise and labor-saving flow regulation, allowing operators to easily manage high-pressure conditions. The metal-to-metal seating mechanism is specifically engineered to withstand extreme temperatures and harsh media, offering enhanced durability compared to standard resilient seated alternatives. Its wafer-style body ensures a compact footprint, reducing overall weight and simplifying the installation process between standard pipe flanges. For procurement professionals, this translates to lower maintenance costs, reduced installation time, and long-term operational stability.

Flow Coefficients (Cv Values)

The flow coefficient is a critical technical index used to measure the flow capacity of a valve. The higher the flow coefficient, the lower the pressure loss upon fluid flowing through the valve. The values of the flow coefficient differ significantly based on the sizes, types, and structural designs of the valves. Valves of different types and specifications should be separately tested to determine their exact flow coefficient values. Even for valves of the same structure, the flow coefficient may vary depending on the direction of fluid flow through the valve. This difference is usually caused by variations in pressure recovery dynamics within the pipeline.

The table below illustrates the flow coefficients of double and triple eccentric butterfly valves. This data serves as a reliable reference for engineering and procurement teams to choose the appropriate valve flow capacity, ensuring optimal system performance and energy efficiency.

Cv represents the volume of water in US gallons at +60°F (+16°C) that flows through the valve per minute under a pressure drop of 1 pound per square inch (psi) or 0.003561424 MPa.

Main External and Connection Dimension

Accurate dimensional data is essential for ensuring reliable integration into existing piping infrastructure. The Main External and Connection Dimension chart below details the precise measurements of the wafer butterfly valve, including face-to-face dimensions, flange compatibility, and overall structural footprint. The compact wafer design is highly advantageous for space-constrained layouts, offering a streamlined profile without compromising structural integrity. By referencing these standardized dimensions, procurement specialists and technical teams can verify pipeline compatibility, mitigate installation risks, and ensure precise alignment with mating equipment.
