ASTM A351 CF8M 316 Triple Eccentric Disc Butterfly Valve supppliers in india

Triple Eccentric Butterfly Valve is a gate valve. The gate is in the shape of a butterfly with a central axis and a disc that connects to the axis. The disc is seated in the body and the axis is connected to the handle outside the valve body. The Triple Offset Eccentric Butterfly Valve is also known as centered axis valve with three offsets. These valves are used to perform at high opening and closing frequency applications and in severe applications. The Triple Eccentric Metal Seated Butterfly Valve can be operated with low torque forces and thermal shocks and pressure peaks can be handled by these valves. A composite stainless steel sealing ring mounted on the disc allows for leak proof design.

The zero friction right angled rotation is possible with the triple eccentric principle. The Three Eccentric Butterfly Valve comes in different standards such as API, ASME and GB standards. The sizes of the valves range from 2 inches to 48 inches. The pressure numbers vary from PN6 through PN64 with different pressure capacities needed for different application types. The Triple Eccentric Butterfly Valve Manufacturers produce these valves for mineral processing applications, oil and gas industries, petrochemical plants, petrochemicals, water distribution, wastewater management and for use in pollution control systems. The triple eccentric valves are used in applications and conditions where the ordinary butterfly valves cannot handle the parameters.
